A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 50% of this population prefers the color green. If 15 buyers are randomly selected, what is the probability that exactly a third of the buyers would prefer green?
Answer:
0.09
Step-by-step explanation:
Given that 50% of this population prefers the color green.
Let p the probability that one person selected from the population prefer the green color of the car. So,
p=0.05
There is only two chance, any person either prefer the green color or not, assuming this holds true for every person, so the mentioned population can be assumed as Bernoulli's population.
By using Bernoulli's theorem, the probability of exactly r success of n randomly selected from the Bernoulli's population is
[tex]P(r)=\binom{n}{r}p^{r}{(1-p)}^{n-r}\cdots(i)[/tex]
Here, 15 buyers are randomly selected, so, n= 15 and
[tex]r= \frac1 3 \times 15=5[/tex]
So, by using equation (i), the probability that exactly 5 buyers would prefer green out of 15 randomly selected buyers is
[tex]P(r=5)=\binom{15}{5}(0.5)^{5}{(1-0.5)}^{15-5}[/tex]
[tex]=\binom{15}{5}(0.5)^{5}{0.5}^{10}[/tex]
[tex]=\binom{15}{5}(0.5)^{15}[/tex]
=0.0916
Hence, the probability that exactly 5 buyers would prefer green out of 15 randomly selected buyers is 0.09.

Step-by-step explanation:
If the height of an equilateral triangle ABC is 5/ 3 cm. Let us write by calculating the area
of this triangle
• Height of the equilateral triangle = 5/3 cm .
To find :• The area of the triangle .
Solution:• First find side :
As we know that:
• Height = √3/2 (side)
=> 5/3= √3/2 (side)
=> side = 10/3√3 cm
• Area of equilateral triangle = √3/4 (side)².
=> Area = √3/4(10/3√3)²
=> Area = √3/4(100/27)
=> Area = 25√3/27
=> Area = 43.30/27
=> Area = 1.60 cm².
Hence, the area of equilateral triangle is 1.60cm²

At a local pizza shop, large pizzas cost $14.50 and small pizzas cost $9.00. On Thursday, the number of large pizzas sold was 3 less than twice the number of small pizzas sold. The total value of all pizzas sold was $640.50. How many of each type of pizza did the pizza shop sell?
Answer:
Small pizzas = 21
Large pizzas = 39
Step-by-step explanation:
The number of small pizzas sold be x
So, the number of large pizzas sold be 2x - 3
And the total value is $640.504
Now the equation would be
$14.50x + $9 × (2x - 3) = $640.50
$14.50x + 18x - $27 = $640.50
$32.50 = $640.50 + $27
$32.50x = $667.50
x = 21
Now the large pizzas is
= 2 × 21 - 3
= 39

Answer:
x=-10
Step-by-step explanation:
15-2(x+5)=25
multiply the 2 by the x and 5 and you get
15-2x-10=25
since the 15 and the negative 10 are on the same side you add them together and get
5 -2x= 25
-5 -5
-2x =20
Then divide the -2/20= -10
Answer:
x = -10
Explanation:
15 - 2 ( x + 5 ) = 25
Distribute 2 through the parentheses
15 - 2x - 10 = 25
Subtract the numbers
5 - 2x = 25
Move constant to the right-hand side and change its sign
-2x = 25 - 5
Subtract the numbers
-2x = 20
Subtract both sides
x = -10

-1 + 4 (6x + 3) = 1/2 (-10x - 10) -5
Answer: x = 60/11
Step-by-step explanation:
-1 + 4 (6x + 3) = 1/2 (-10x - 10) -5
Multiply the 1/2 with -10x, and -10.
Let's look on the side that we are working on now.
New equation:
- 1 + 4 (6x + 3) = -5x - 5 - 5
-5-5= -10
-1+4(6x+3)=-10-5x
Next we remove the brackets.
-1 + 4 * 6x + 3 = -10x -5
Now we bring the x's on one side and the non-x's on the other. When we bring a positive x on the other side of an equal sign, it becomes negative. If we bring a negative x on the other side of an equal sign, it becomes positive.
10x * 6x = 1 - 4 - 3 - 5
60x = 1 - 12
60x = -11
x = 60/11

Jane and her friends are going on a hiking trip. Jane wants to make snack packs to take on a trip. She has 24 apples and 36 small bags of trail mix. Each snack pack must have the same number of apples and the same number of bags of trail mix. What is the greatest number of snack packs Jane can make? Explain.
Answer:
The greatest number of snack packs Jane can make is 12 snack packs
Step-by-step explanation:
We solve this question using the greatest common factor method
First step would be to find the factors of 24 and 36
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
Then the greatest common factor amongst the above factors for 24 and 36 is 12.
Therefore, the greatest number of snack packs that she can make is 12 packs.

which could be the function graphed below?
f(x) = √x - 5+1
f(x) = √x-2
f(x) = √x
f(x) = √x+4
Answer:
Option (4)
Step-by-step explanation:
Parent function of the graph attached,
f(x) = [tex]\sqrt{x}[/tex]
If the given function is shifted by 'a' units to the left,
Rule for the transformation is,
g(x) = f(x + a)
So the transformed function will be in the form of g(x) = [tex]\sqrt{x+a}[/tex]
Therefore, from the given options, f(x) = [tex]\sqrt{x+4}[/tex] will match our requirements.
Option (4) will be the answer.

The points A, B, and C lie on a line so that AB = 12 cm and BC = 13.5 cm. Find the length of segment AC. Give all possible answers.
Give two possible answers. Not just one please.
Answer:
25.5 and 1.5
Step-by-step explanation:
AC = 12 cm
BC = 13.5 cm
12 + 13.5 = 25.5 cm
13.5 - 12 = 1.5 cm
The possible length of segment AC is 25.5 cm and 1.5 cm.
What is a line segment?A line segment is a part of line that is bounded by two distinct end-points. A line segment has a fixed length. Figures such as a triangle, polygon, hexagon, square are made of different numbers of line segments.
For the given situation,
The points A, B, and C lie on a line.
Length AB = 12 cm
BC = 13.5 cm
The possible length of segment AC can be found by adding and subtracting the lengths of AB and BC.
a) Length of AC = [tex]13.5+12[/tex]
⇒ [tex]25.5[/tex] cm
b) Length of AC = [tex]13.5-12[/tex]
⇒ [tex]1.5[/tex] cm
Hence we can conclude that the possible length of segment AC is 25.5 cm and 1.5 cm.
