Eighty percent of the students graduating from high school in a small Iowa farm town attend college. The town's chamber of comme
anyanavicka [17]

Answer: 0.6368

Step-by-step explanation:

Given : The proportion of z-test for population mean : \hat{p}= 0.80

Sample size : n=45

We assume that this is normally distributed.

The test statistic for population proportion :-

z=\dfrac{\hat{p}-p_0}{\sqrt{\dfrac{p_0(1-p_0)}{n}}}

Now, for p_0=0.82, we have

z=\dfrac{0.80-0.82}{\sqrt{\dfrac{0.82(1-0.82)}{45}}}\\\\\approx-0.35

By using the standard normal distribution table , the probability that at least 82% of the surveyed students will be attending college will be :-

P(p\geq0.82)=P(z\geq-0.35)\\\\=1-P(z

Hence, the probability that at least 82% of the surveyed students will be attending college = 0.6368

Beth is flying a kite with 300 feet of string. The kite gets stuck in a tree, so she ties the other end of the string to a rock
Paraphin [41]

Answer:

\displaystyle 172.1 ft

Step-by-step explanation:

<u>refer </u><u>the</u><u> attachment</u>

let the string be hypotenuse and

the height be h And the angle be 35°

given that,

  • hypotenuse:300ft
  • angle:35°

since we are given the hypotenuse and want to figure out the opposite side we'll use <u>sin</u><u> </u>function

so our equation would be

\displaystyle  \sin( {35}^{ \circ} )  =  \frac{h}{300}

cross multiplication:

\displaystyle h= 300 \sin( {35}^{ \circ} )

by using calculator we obtain:

\displaystyle h = 172.1

hence,

about <u>1</u><u>7</u><u>2</u><u>.</u><u>1</u><u>f</u><u>t</u><u> </u><u> </u>far up the tree is the kite
