Answer:

sin q = 14/50

cos q = 24/25

tan q = 7/24

sin r = 24/25

cos r = 7/25

tan r = 24/7

Answer:

12 seconds.

Step-by-step explanation:

Let t represent time taken by code to sort an array of 24 elements.

We have been given that an algorithm takes 4 seconds to sort an array of 8 elements. We are asked to find the time it will take for same code to sort an array of 24 elements.

We will use proportions to solve our given problem.

$\frac{\text{Time}}{\text{Array of elements}}=\frac{4}{8}$

$\frac{t}{24}=\frac{4}{8}$

$\frac{t}{24}\cdot 24=\frac{4}{8}\cdot 24$

$t=\frac{4}{1}\cdot 3$

$t=12$

Therefore, it will take 12 seconds for the same code to sort an array of 24 elements.

Colton makes the claim to his classmates that less than 50% of newborn babies born this year in his state are boys. To prove thi

alexdok [17]

Answer:

Null hypothesis: $p \leq 0.5$

Alternative hypothesis: $p > 0.5$

The statistic is given by:

$z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}$ (1)

Replacing we got:

$z=\frac{0.512-0.5}{\sqrt{\frac{0.5(1-0.5)}{344}}}=0.445$

Step-by-step explanation:

Information given

n=344 represent the random sample taken

X=176 represent the anumber of boys babies

$\hat p=\frac{176}{344}=0.512$ estimated proportion of boys babies

$p_o=0.5$ is the value that we want to check

z would represent the statistic

$p_v$ represent the p value

Hypotheis to verify

We want to check if the true proportion of boys is less than 50% then the system of hypothesis are .:

Null hypothesis: $p\leq 0.5$

Alternative hypothesis: $p > 0.5$

The statistic is given by:

$z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}$ (1)

Replacing we got:

$z=\frac{0.512-0.5}{\sqrt{\frac{0.5(1-0.5)}{344}}}=0.445$

In triangle ABC△ }∠B=90∘ If sin A= 5/13, what is cos C?

KiRa [710]

this problem is tricky, if you actually draw it out you will see the side opposite to A is the adjacent side to C which means sin(A)=cos(C)=5/13

Hope this helped!
