The weight of football players is normally distributed with a mean of 180 pounds and a standard deviation of 20 pounds. what is the probability of a player weighing less than 215 pounds?

Answers

Answer 1

Answer:

Given:

mu = 200 lb, the mean sigma = 25 the standard deviation

For the random variable x = 250 lb, the

z-score is z = (x - mu) / sigma = (250 - 200) / 25 = 2

From standard tables for the normal distribution, obtain

P(x < 250) = 0.977

Answer: 0.977

If AB is 16, then AD is 8.

If AB = 12 and CB = 10, then the height of the triangle is 8.

Step-by-step explanation:

AD = [tex]\frac{AB}{2}[/tex], so AD is equal to 8.

Use the Pythagorean Theorem, [tex]\sqrt{10^{2} - 6^{2}}[/tex] equals 8, so the height of the triangle is equal to 8.

Oranges (lb) Price ($)

2--------- $3

3--------- $4.50

5--------- $7.50

Answer:

proportional relationship. Exist

Step-by-step explanation:

To check for propottionality:

2 = 3k

Solve for k = constant of proportionality

2/3 = 3k/3

2/3 = k

Quantity at price = 4.50

Price * k = quantity

4.50 * 2/3 = 3

Quantity at price = 7.50

Price * k = quantity

7.50 * 2/3 = 5

Hence, proportional relationship. Exist

Answer:

Step-by-step explanation:

Let's fill x and y and we'll see which one is right

a) 0 = -3(-7+7)(-7+4)

<=> 0 = 3 * 0 * -3

<=> 0 = 0 => true

b) 0 = -0.5(-7-7)(-7+4)

<=> 0 = -0.5 * -14 * -3

<=> 0 =  -21 => false

c) 0 = (-7-7)(-7-4)

<=> 0 = -154 => false

d) 0 = 2(-7+7)(-7-4)

<=> 0 = 0 => true

so both a and d are right for (-7,0). Now let's for (-4,0)

a) 0 = -3(-4+7)(-4+4)

<=> 0 = 0 => true

d) 0 = 2(-4+7)(-4-4)

When two angles of an isosceles triangle are given in the form of x, then the value of a single angle can have two possible outcomes those are:

X can be [tex]56.66^\circ[/tex]X can be [tex]53.33^\circ[/tex]

Given,

Two angles: X and [tex]\rm{X}+10[/tex]

As we know in an Isosceles triangle, the sum of all the angles is equal to[tex]180^\circ[/tex] and any of the two angles can be equal.

There can be two possible outcomes:

Case 1. When the two equal angles are X

[tex]\begin{aligned}\text{X}+\text{X}+(\text{X+10})&=180\\3\text{X}+10&=180\\3\text{X}&=180-10\\\text{X}&=\dfrac{170}{3}\\\text{X}&=56.66^\circ\end{aligned}[/tex]

Case 2: When the two equal angles are [tex]\rm{X}+10[/tex]

[tex]\begin{aligned}\text{X}+(\text{X}+10)+(\text{X}+10)&=180\\3\text{X}+20&=180\\3\text{X}&=180-20\\\text{X}&=\dfrac{160}{3}\\\text{X}&=53.33^\circ\end{aligned}[/tex]

Therefore, the two possible values of X can be [tex]56.66^\circ[/tex] and [tex]53.33^\circ[/tex]

A linear equation is an equation in which each term has at max one degree. The correct option is D, y = -x + 56.

What is a linear equation?

A linear equation is an equation in which each term has at max one degree. Linear equations in variables x and y can be written in the form,

y = mx + c

Linear equation with two variables, when graphed on the cartesian plane with axes of those variables, give a straight line.

Given that the temperature was 56 degrees this morning but dropped one degree per hour through the rest of the day. Therefore, an equation in slope intercept form to represent the temperature of the day at any given hour is,

y = 56 - x

y = -x + 56

Hence, the equation in slope intercept form to represent the temperature of the day at any given hour is y = -x + 56.

a woman is 5 times as old as her daughter in 15 years time to be two times as old as her daughter to find a mother's presentsage​

Answers

Answer:

25 years.

Step-by-step explanation:

Given that a woman is 5 times as old as her daughter, while in 15 years time it will be two times as old as her daughter, to find a mother's presents age the following calculation must be performed:

5 x 5 = 25

25 + 15 = 40

40/2 = 20

5 + 15 = 20

Thus, the present age of the mother is 25 years, while that of her daughter is 5 years, with which the mother is five times the age of her daughter. In 15 years, the mother will be 40 and her daughter 20, with which she will only be twice her age.

Mary's dog weights 185 pound. Her dog needs to lose between 9 and 15 pounds. Between what two percentages rounded to the nearest whole number, should Mary's dog lose weight with respect to its current weight 185 pounds.

Answers

Answer:Mary' s dog should loose weight between  92%-95%

Step-by-step explanation:

Step 1

Mary's dog current  weight=  185 pound

weight to loose =Between  9 and 15 pounds

 Loosing 9 pounds , the dog"s new weight will be = 185- 9= 176 pounds

also

 Loosing 15 pounds , the dog"s new weight will be = 185- 15= 170pounds

Step 2

Percentage  of weight loss to current weight when he looses 9 pounds=

= 176/185 x 100

=0.95 x100=95%

Percentage  of weight loss to current weight when he looses 15 pounds=

= 170/185 x 100

=0.9189 x100

=91.89= 92%

Therefore Mary' s dog should loose weight between  92%-95%

Answer:

Step-by-step explanation:

Steve is turning half his backyard into a chicken fan. His backyard is a 24 m x 45 m rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. How many meters of fencing will Steve need?

We are to find the meters of fencing for the diagonal.

We solve the question using Pythagoras Theorem

= c² = a² + b²

Where

c = Diagonal

a = Width

b =Length

Diagonal² = Width² + Length ²

Hence:

Diagonal ² = 45² + 24²

Diagonal = √45² + 24²

Diagonal = √(2601)

Diagonal = 51 m

Therefore, the meters of fencing for the diagonal that Steve would be needing = 51 meters

Forman1911THE MATCH(There never was a time when the world was without fire, but there was a time when men did not know how to kindle fire; and after they learned how to kindle one, it was a long, long time before they learned how to kindle one easily. In these days we can kindle a fire without any trouble, because we can easily get a match; but we must remember that the match is one of the most wonderful things in the world, and that it took men thousands of years to learn how to make one. Let us learn the history of this familiar little object, the match.)Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In the early history of the world, nature had to kindle all the fires, for man by his own effort was unable to produce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by natureby a volcano, perhaps, or by a stroke of lightning. These firebrands were carried to the home and used in kindling the fires there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would sometimes be extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble.In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar. Which line from the parentheses paragraph shows the value of the match?A. but there was a time when men did not know how to kindle fireB. it was a long, long time before they learned how to kindle one easilyC. There never was a time when the world was without fireD. In these days we can kindle a fire without any trouble, because we can easily get a match
