Answer:

The plane was 923.5 feet high after 10 seconds.

Step-by-step explanation:

Angle made by plane with ground during take off = x = 20°

Average speed of plane = 270 ft/s

Let the height of Plane after 10 seconds from the takeoff = H

Distance covered by plane in 10 seconds = 270 ft/s × 10 sn= 2700 ft

According to trigonometric ratios:

$\Sin \theta=\frac{Perpendicular}{Hypotenuse}$

Here , perpendicular = H

Hypotenuse = 2700 ft

$\Sin 20^o=\frac{H}{2700 ft}$

$H=0.342020\times 2700 ft=923.45 ft\approx 923.5 ft$

The plane was 923.5 feet high after 10 seconds.

I’m not sure how to do this. Plz help and show the work

3. 65x5= 325
she traveled 325 feet in 5 minutes
4. 3(6) +5 = 23
6cube - 10 =206
5. area of the triangle is 1/2x base x height
so 1/2 x 15 x 10 = 75
7. they'll have 6 sections. 3/4 divided by 1/8 is 6

hope this helps :)

Answer:

(A) $H_0$ : μ = 22 ; $H_A$ : μ ≠ 22

(B) Value of the test statistic = -2.69

Step-by-step explanation:

We are given that a local bottler in Hawaii wishes to ensure that an average of 22 ounces of passion fruit juice is used to fill each bottle. He takes a random sample of 65 bottles. The mean weight of the passion fruit juice in the sample is 21.54 ounces. Assume that the population standard deviation is 1.38 ounce.

We have to test the accuracy of the bottling process.

(A) Let, NULL HYPOTHESIS, $H_0$ : $\mu$ = 22 ounces {means that an average of 22 ounces of passion fruit juice is used to fill each bottle}
