Since this is a right triangle, you can use the main trig functions sin, cos, and tan. We must use sin for this problem because sin= opp/hyp. Plug in the numbers to this function. Sin (53) = a/25. Thus when you cross multiply, you get a= sin (53) x 25. When you plug it into a calculator the answer should come out to 19.97

Eddie walks 450.25 feet in 2.5 minutes. Which value is closest to the number of yards Eddie walks in 1 minute?

Anna71 [15]

Eddie walks 60.03 yards in 1 minute using proportion.

What is proportion?

The term proportionality refers to any relationship that has the same ratio every time. The proportional relationship between the two supplied ratios is defined by an equation. In other terms, the proportion declares that the two fractions or ratios are equal. For instance, the average number of apples per tree determines the proportionality between the quantity of apples in a crop and the number of trees in the orchard.

Here let us take time and distance as proportional values,

=> $\frac{distance}{Time}$

=> 450.25/2.5 = x/1

=> x = 180.1 feet.

To convert feet to yards divide the length by 3. then

=> 180.1/3=60.03 yards,

Therefore Eddie Walks 60.03 yards in 1 minute.

I need help breaking this down

sergeinik [125]

Answer:

see explanation

Step-by-step explanation:

Given

2cosΘ - $\sqrt{2}$ = 0 ( add $\sqrt{2}$ to both sides )

2cosΘ = $\sqrt{2}$ ( divide both sides by 2 )

cosΘ = $\frac{\sqrt{2} }{2}$

Since cosΘ > 0 then Θ is in first and fourth quadrants, hence

Θ = $cos^{-1}$ ( $\frac{\sqrt{2} }{2}$ ) = $\frac{\pi }{4}$

Θ = 2π - $\frac{\pi }{4}$ = $\frac{7\pi }{4}$

solutions are Θ = $\frac{\pi }{4}$ , $\frac{7\pi }{4}$

A random sample of n D 225 and xN D 21 was drawn from a normal population with a known

Rainbow [258]

Using the z-distribution, the 95% confidence interval of the population mean is: (17.5, 24.5).

<h3>What is a z-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm z\frac{\sigma}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

z is the critical value.

n is the sample size.

$\sigma$ is the standard deviation for the population.

In this problem, we have a 95% confidence level, hence $\alpha = 0.95$ , z is the value of Z that has a p-value of $\frac{1+0.95}{2} = 0.975$ , so the critical value is z = 1.96.
