Answer:

7.3

Step-by-step explanation:

In order to find the hypotenuse, we just need to use the Pythagorean Theorem.

Remember, that this theorem only works for right triangles.

This theorem states that a^2+b^2=c^2

This is where a and b are legs of the triange, and c is the hypotenuse.

Knowing this, we can plug our values in.

6.4^2+3.5^2=c^2

Simplify.

41.344+12.25=c^2

53.594=c^2

Root both sides.

c=7.32 (about)

Round that to tenths.

c=7.3

A tennis player keeps track of the number of successful first serves he makes. During the first 8 service points of a game, only
Andru [333]

Answer:

He needs 7 more consecutive successful first serves to raise his first serve percentage to 60%.

Step-by-step explanation:

After n consecutive serves, his total number of serves is going to be n+8, since he has already served 8 times. In the best case, his number of successful first serves is n+2.

His percentage of succesful first serves is the division of the number of succesful first serves divided by the total number of serves. So

P = \frac{n+2}{n+8}

We want P = 0.60. So

0.6 = \frac{n+2}{n+8}

n+2 = 0.6*(n+8)

n + 2 = 0.6n + 4.8

n - 0.6n = 4.8 - 2

0.4n = 2.8

n = \frac{2.8}{0.4}

n = 7

He needs 7 more consecutive successful first serves to raise his first serve percentage to 60%.

The area of Erin's circle to the nearest hundredth is 50.24 in².

<h3>What is the area of the circle?
</h3>

A circle is a bounded figure which points from its center to its circumference is equidistant.

Area of a circle = πr²

Where :

  • π = pi = 3.14
  • R = radius

3.14 X 4²

(3.14) (4) (4) = 50.24 in²

A random sample of 400 items from a population shows that 160 of the sample items possess a given characteristic. A random sampl
Free_Kalibri [48]

Answer: (0.04,\ 0.21)

Step-by-step explanation:

The confidence interval for population proportion is given by :-

p_1-p_2\pm z_{\alpha/2}\sqrt{\dfrac{p_1(1-p_1)}{n_1}+\dfrac{p_2(1-p_2)}{n_2}}

Given : Significance level : \alpha=1-0.99=0.01

Critical value : z_{\alpha/2}=2.576

n_1=400 ;\ p_1=\dfrac{160}{400}=0.4

n_2=400 ;\ p_2=\dfrac{110}{400}=0.275

Then a 99% confidence interval is constructed to estimate the difference in population proportions which possess the given characteristic will be :-

0.4-0.275\pm (2.576)\sqrt{\dfrac{0.4(1-0.4)}{400}+\dfrac{0.275(1-0.275)}{400}}\\\\\approx0.125\pm0.085=(0.125-0.085,0.125+0.085)=(0.04,\ 0.21)

Hence, the resulting confidence interval is (0.04,\ 0.21) .
