PLEASE HELP! The AHS Football Team Did A Weigh-in At The Start Of Training Camp. The Weights Of The Players

Answers

Answer 1

Answer:

2.28% of players are under 86kg

Step-by-step explanation:

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 zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

The weights of the players were distributed normally with a mean of 98kg and a standard deviation of 6kg.

This means that [tex]\mu = 98, \sigma = 6[/tex]

What percentage of players are under 86kg?

The proportion is the pvalue of Z when X = 86. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{86 - 98}{6}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a pvalue of 0.0228

0.0228*100% = 2.28%

2.28% of players are under 86kg

34. CONSTRUCTION A construction worker is working on the roof of a
building. A drop of paint falls from a rafter that is 225 feet above the
ground. After how many seconds does the paint hit the ground?

Answers

Answer:

t = 6.77 s

Step-by-step explanation:

Given that,

A drop of paint falls from a rafter that is 225 feet above the  ground.

We need to find the time when the paint hit the ground. Let the time be t.

Using the second equation of kinematics i.e.

[tex]s=ut+\dfrac{1}{2}at^2[/tex]

Where

u = 0 (initial velocity is 0 as it was at rest)

a = g

So,

[tex]225=\dfrac{1}{2}\times 9.8t^2\\\\t=\sqrt{\dfrac{2\times 225}{9.8}} \\\\t=6.77\ s[/tex]

So, it will hit the ground at 6.77 s.

Step-by-step explanation:

Please, What is the answer?

Answers

Answer: You have the correct answer. It's choice A.

Explanation:

You can verify this by plugging each root into the equation.

So for instance, plug in x = -2 and we get

f(x) = -3*(x+2)*(x-sqrt(3))*(x-4)

f(-2) = -3*(-2+2)*(-2-sqrt(3))*(-2-4)

f(-2) = -3*(0)*(-2-sqrt(3))*(-2-4)

f(-2) = 0

This verifies x = -2 is a root.

All that matters is that zero buried in there in the second to last step. Multiplying 0 by anything leads to 0. The other roots are verified in the same manner. The -3 out front is the leading coefficient.

----------------

Extra info:

Choice B is eliminated because (x+3) being a factor implies that x = -3 is a root. But this isn't listed in the instructions.Choice C is a similar story to choice BChoice D is eliminated since -sqrt(3) is not one of the listed roots, so (x+sqrt(3)) is not a factor.
X = -2 because is a root

Solve for x.

Azim wants to buy a tablet computer that is priced 180.50 if the sales tax rate on the computer is 8% how many dollars and cents will Azim spend on the sales tax only

Answers

Answer: 98.1%

Explanation:

A 10% sale means that the post-sale price of the item is now 90%, or 0.9 of the original cost of the item. We then apply 9% sales tax by multiplying the 0.9 by 109%, or 1.09. 0.9 * 1.09 = .981, so the total cost of the item is 98.1% of the original pre-sale sticker price.

For percentage problems that do not deal with a specific starting number, it is always helpful to plug in 100 for the starting number. Here, we would then have a post-sale price of 90 dollars, and if we calculate the sales tax for the 90-dollar item it would be 90 * 0.09 = $8.10. THis gives us a total cost of 90 + 8.10 = $98.10, or 98.1% of the original 100-dollar price.

Answer: 98.1 % (other answer above got it as well but hope this helps anyway :)

Answers

Answer:

209 robberies

Step-by-step explanation:

Robberies last year =348

Robberies has reduced by 40% which means there are (100-40)% = 60% robberies this year.

Number of robberies this year= 60% of 348 = 60/100 × 348 = 208.8

To the nearest whole number = 209

There are 209 robberies this year.

Henry constructed circle A with a radius of 4 units. He then created a sector
as shown in the figure below. Which of the following expressions would help
him find the area of the shaded sector?

Answers

Answer:

C

Step-by-step explanation:

area of circle is found by [tex]\pi[/tex][tex]r^{2}[/tex]

r=4 so 4*4=16

so A=16[tex]\pi[/tex]

we are finding area of shaded part so 45/360(16[tex]\pi[/tex])

The area of the shaded sector is (45/360)16π square units if Henry constructed circle A with a radius of 4 units option (C) is correct.

What is a circle?

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

It is given that:

Henry constructed circle A with a radius of 4 units.

Henry then created a sector as shown in the figure below.

As we know, the area of the sector can be find using the formula:

Area of the sector = (θ/360)πr²

Here, θ is the central angle

r is the radius

π = 3.141

r = 4 units

θ = 45 degrees

A = (45/360)π(4)²

A = (45/360)16π square units

Thus, the area of the shaded sector is (45/360)16π square units if Henry constructed circle A with a radius of 4 units option (C) is correct.

nine more than the product of 22 and Gordons height​

Answers

Answer:

9 + 22h

Explanation:

The question is incomplete as Gordon's height is not given. To solve further, we will represent this height with h

So, we have:

nine more than the [tex]product[/tex] of 22 and [tex]Gordons\ height[/tex]

More than, in this case means plus (+)

nine + the [tex]product[/tex] of 22 and [tex]Gordons\ height[/tex]

Rewrite nine as 9 and substitute h for Gordons height

9 + the [tex]product[/tex] of 22 and h

product, in this case means multiplication (*)

9 + 22 * h

So, the expression is:
