Note that A=lw, where A is the area, l is the length, and w is the width.  Substituting our values in, we have:

\frac{5w}{9} = \frac{25}{54}

Multiplying by \frac{9}{5} gives:

w=\frac{5}{6}

So the width is \frac{5}{6} miles.

Math SAT: Suppose the national mean SAT score in mathematics was 510. In a random sample of 50 graduates from Stevens High, the
sukhopar [10]

Answer:

Mean SAT score for Stevens High graduates are not the same as the national average.    

Step-by-step explanation:

We are given the following information in question:

Population mean, μ = 510

Sample mean, \bar{x} = 501

Sample size, n = 50

Alpha, α = 0.10

Sample standard deviation, s = 30

First, we design the null and the alternate hypothesis

H_{0}: \mu = 510\\H_A: \mu \neq 510

We use Two-tailed t test to perform this hypothesis.

Formula:

t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n-1}} } Putting all the values, we have,

t_{stat} = \displaystyle\frac{501 - 510}{\frac{30}{\sqrt{49}} } = -2.1 Now,

t_{critical} \text{ at 0.10 level of significance, 49 degree of freedom } = \pm 1.6765 Since,              

t_{stat} < t_{critical}

We reject the null hypothesis and fail to accept it.

We accept the alternate hypothesis and mean SAT score for Stevens High graduates are not the same as the national average.

How do you write 32,005,008 in expanded form
Karolina [17]
To write 32,005,008 in expanded form, you write it out like this: <span>32,005,008 = 30,000,000 + 2,000,000 + 5,000 + 8.

I know this because I learned it in 3rd grade at school.

Hope I helped!

What is the center? (X-0.5)^2+(y-3.5)^2=16
pantera1 [17]

Answer:

(.5,3.5) is the center and 4 is the radius

Step-by-step explanation:

(X-0.5)^2+(y-3.5)^2=16

This is written in the form

(x-h)^2 + (y-k)^2 =r^2

where (h,k) is the center and r is the radius

(X-0.5)^2+(y-3.5)^2=4^2

(.5,3.5) is the center and 4 is the radius
