Answer:

In Right Δ ABC with right angle B,

∠A=(3 x -8)°, ∠B=90°, ∠C=(x-2)°

∠A+∠B+∠C=180°[∠ sum property of triangle]

3 x-8+90 + x-2=180

Adding and subtracting like terms

4 x-10+90=180

4 x+80=180

4 x=180-80

4 x=100

x=100/4

x=25°

∠A=3×25-8=75-8=67°

This figure shows the nose cone of a rocket used for launching satellites. The nose cone houses the satellite until the satellit

Elena-2011 [213]

see the attached figure to better understand the problem

we know that

The volume of the cone is equal to

$V=\frac{1}{3} \pi r^{2} h$

in this problem

$r=\frac{6}{2} =3\ ft\\ \\ h=15\ ft$

Substitute the values in the formula above

$V=\frac{1}{3}* \pi* 3^{2}* 15\\ \\ V=45\pi \ ft^{3}$

therefore

the answer is

The volume of the nose cone is $45\pi \ ft^{3}$

Eric is studying people's typing habits. He surveyed 525 people and asked whether they leave one space or two spaces after a per

hichkok12 [17]

Answer:

The confidence interval is (0.81, 0.87).

Step-by-step explanation:

There's 90% confidence that population proportion is within the interval obtained from the following formula:

$\hat{p}\pm z_{\alpha/2}\sqrt{\frac{\hat{p}*(1-\hat{p})}{n}}$

Knowing that the sample size, $n=525$ we obtain the proportion of people from the sample who leave one space after a period as $\hat{p}=\frac{440}{525}=0.8381\approx 0.84$ .

We then look for the critical value:

$z_{\alpha/2}=1.645$

Now we can replace in the formula to obtain the confidence interval:

$0.84\pm 1.645\sqrt{\frac{0.84*(1-0.84)}{525}}= (0.8137; 0.8663)$

Therefore we can say that there's 90% probability that the population proportion of people who leave one space after a period lies between the values (0.8137; 0.8663).

Grandpa ernie is shrinking! Over the past 4 years, his hight decressed by a total of 2.4cm. It decresed by the same amount each

dolphi86 [110]

Answer: 0.6 cm

Step-by-step explanation:

Given : Over the past 4 years, Grandpa Ernie's height decreased by a total of 2.4 cm.

If the height is decreased by the same amount each year.

Then, the change in Grandpa Ernie's height each year will be =

Total decrease in height ÷ 4

= 2.4 cm ÷ 4 = 0.6 cm

Hence, the change in Grandpa Ernie's height each year = 0.6 cm
