[tex]s\geq 36[/tex]
Step-by-step explanation:
Step 1, how many knives to buy?
The restaurant already has 262 knives. We can subtract this number from their needed 694 knives to find how many they still need:
[tex]694-262=432[/tex] knives.
Step 2, how many sets of knives?
The restaurant needs to buy 432 knives. We know the knives come in sets of 12, so we can divide to find the # of packs she needs to buy, determined by variable s.
Notice how the restaurant needs to buy a minimum of 694 knives, hence we use a greater or equal than symbol:
[tex]\fbox{\frac{432}{12} \geq s}\\[/tex][tex]s\geq \frac{432}{12}[/tex]
[tex]s\geq 36[/tex]
I hope this helps! Let me know if you have any questions :)
The inequality that can be used to determine s, the minimum number of sets of knives Savannah should buy is 694 ≥ 262 + 12s.
Given that;
The restaurant needs at least 694 knives. There are currently 262 knives.
Here, each set on sale contains 12 knives.
Let us assume that;
The minimum number of sets of knives Savannah should buy = s
Hence the inequality for the given condition is,
694 ≥ 262 + 12s

An angle measures. What is the measure of its complement? (b) An angle measures 48 . What is measure 26 of its supplement?
The amounts of nicotine in a certain brand of cigarette are normally distributed with a mean of 0.974 g and a standard deviation of 0.325 g. The company that produces these cigarettes claims that it has now reduced the amount of nicotine. The supporting evidence consists of a sample of 48 cigarettes with a mean nicotine amount of 0.918 g. Assuming that the given mean and standard deviation have NOT changed, find the probability of randomly seleting 32 cigarettes with a mean of 0.917 g or less.
P(M < 0.917 g) = __________
Answer:
P(M < 0.917 g) = 0.1611.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 0.974 g and a standard deviation of 0.325 g.
This means that [tex]\mu = 0.974, \sigma = 0.325[/tex]
Sample of 32:
This means that [tex]n = 32, s = \frac{0.325}{\sqrt{32}}[/tex]
Fnd the probability of randomly selecting 32 cigarettes with a mean of 0.917 g or less.
This is the p-value of Z when X = 0.917. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.917 - 0.974}{\frac{0.325}{\sqrt{32}}}[/tex]
[tex]Z = -0.99[/tex]
[tex]Z = -0.99[/tex] has a p-value of 0.1611.
So
P(M < 0.917 g) = 0.1611.

1. Leo ran around the track three times. The track was 400 meters. How many kilometers did he run altogether?
Noel and Casey both start at the same place. Noel walks due south and Casey walks due east. After some time has passed, Noel is 6 miles south and Casey is 8 miles east. At this time, Noel is walking at a rate of 2 mph and Casey is walking at a rate of 1 mph. How fast is the distance between them increasing at this time
Answer:
2.04 miles per hour
Step-by-step explanation:
Given
Noel
[tex]n_1 =6miles[/tex]
[tex]r_1 = 2mph[/tex]
Casey
[tex]c_1 = 8miles[/tex]
[tex]r_2 =1mph[/tex]
Required
The rate at which the distance increases
Their movement forms a right triangle and the distance between them is the hypotenuse.
At [tex]n_1 =6miles[/tex] and [tex]c_1 = 8miles[/tex]
The distance between them is:
[tex]d_1 = \sqrt{n_1^2 + c_1^2}[/tex]
[tex]d_1 = \sqrt{6^2 + 8^2}[/tex]
[tex]d_1 = \sqrt{100}[/tex]
[tex]d_1 = 10miles[/tex]
After 1 hour, their new position is:
New = Old + Rate * Time
[tex]n_2 = n_1 + r_1 * 1[/tex]
[tex]n_2 = 6 + 2 * 1 = 8[/tex]
And:
[tex]c_2 = c_1 + r_2 * 1[/tex]
[tex]c_2 = 8 + 1 * 1 = 9[/tex]
So, the distance between them is now:
[tex]d_2 = \sqrt{n_2^2 + c_2^2}[/tex]
[tex]d_2 = \sqrt{8^2 + 9^2}[/tex]
[tex]d_2 = \sqrt{145}[/tex]
[tex]d_2 = 12.04[/tex]
The rate of change is:
[tex]\triangle d = d_2 -d_1[/tex]
[tex]\triangle d = 12.04 -10[/tex]
[tex]\triangle d = 2.04[/tex]

Step-by-step explanation:
In a triangle, the largest angle is opposite the longest side. The smallest angle is opposite the shortest side.
This triangle has 2 given angles, 50° and 60°.
We can find the measure of the third angle, x.
50 + 60 + x = 180
x + 110 = 180
x = 70
The three angles have measures 50°, 60°, and 70°.
The shortest side is opposite the smallest angle. That is side a.
The longest side is opposite the largest angle. That is side b.
The order from longest to shortest is

A group of campers is going to occupy campsites at a campground. There are 16 campsites from which to choose. In how many ways can the campsites be chosen?
Answer:
The campsites can be chosen in 5,765,760 different ways.
Step-by-step explanation:
Given that a group of campers is going to occupy 6 campsites at a campground, and there are 16 campsites from which to choose, to determine in how many ways the campsites can be chosen, the following calculation must be performed:
16 x 15 x 14 x 13 x 12 x 11 = X
240 x 182 x 132 = X
240 x 24,024 = X
5,765,760 = X
Therefore, the campsites can be chosen in 5,765,760 different ways.

Answer:
The height is 8 cm
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
72 = 1/2 (18)h
72 = 9h
Divide each side by 9
72/9 = 9h/9
8 = h
The height is 8 cm
Answer:
8cm
Step-by-step explanation:
let y represent height
Area of a triangle=½base×height=72cm²
72cm²=½×18cm×y
72cm²=9cmy
72cm²/9cm=9cmy/9cm
8cm=y

The resting heart rate for an adult horse should average about µ = 47 beats per minute with a (95% of data) range from 19 to 75 beats per minute. Let x be a random variable that represents the resting heart rate for an adult horse. Assume that x has a distribution that is approximately normal.
Required:
a. What is the probability that the heart rate is less than 25 beats per minute?
b. What is the probability that the heart rate is greater than 60 beats per minute?
c. What is the probability that the heart rate is between 25 and 60 beats per minute?
Answer:
a. 0.0582 = 5.82% probability that the heart rate is less than 25 beats per minute.
b. 0.1762 = 17.62% probability that the heart rate is greater than 60 beats per minute.
c. 0.7656 = 76.56% probability that the heart rate is between 25 and 60 beats per minute
Step-by-step explanation:
Empirical Rule:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean:
[tex]\mu = 47[/tex]
(95% of data) range from 19 to 75 beats per minute.
This means that between 19 and 75, by the Empirical Rule, there are 4 standard deviations. So
[tex]4\sigma = 75 - 19[/tex]
[tex]4\sigma = 56[/tex]
[tex]\sigma = \frac{56}{4} = 14[/tex]
a. What is the probability that the heart rate is less than 25 beats per minute?
This is the p-value of Z when X = 25. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{25 - 47}{14}[/tex]
[tex]Z = -1.57[/tex]
[tex]Z = -1.57[/tex] has a p-value of 0.0582.
0.0582 = 5.82% probability that the heart rate is less than 25 beats per minute.
b. What is the probability that the heart rate is greater than 60 beats per minute?
This is 1 subtracted by the p-value of Z when X = 60. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{60 - 47}{14}[/tex]
[tex]Z = 0.93[/tex]
[tex]Z = 0.93[/tex] has a p-value of 0.8238.
1 - 0.8238 = 0.1762
0.1762 = 17.62% probability that the heart rate is greater than 60 beats per minute.
c. What is the probability that the heart rate is between 25 and 60 beats per minute?
This is the p-value of Z when X = 60 subtracted by the p-value of Z when X = 25. From the previous two items, we have these two p-values. So
0.8238 - 0.0582 = 0.7656
0.7656 = 76.56% probability that the heart rate is between 25 and 60 beats per minute

Write the equation of the line passing through the point (6,-9) with slope -5/6.
Answer:
The equation is y = -5/6 x-4
Step-by-step explanation:
The equation of a line in slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = -5/6 x+b
Substitute in the point
-9 = -5/6(6) +b
-9 = -5+b
Add 5 to each side
-4 = b
The equation is y = -5/6 x-4

Write an equation and solve for angle G? Show work
Answer:
50
Step-by-step explanation:
Complementary angles mean that the sum of the angles given is 90°. Therefore, as G and H are complementary, this means that G+H=90
G+H=90
(2x+10) + (x+20) = 90
Add values on left side
3x+30=90
Subtract 30 from both sides
3x=60
Divide both sides by 3
x=20
Since we now know the value of x, we can plug that in to G (2x+10) to get 2(20)+10 = 50 = G
