Answer:

Option B - 65%

Step-by-step explanation:

Given : Suppose the x-axis of a density graph represents someone's height in inches. If the area under the density curve from 60 inches to 70 inches is 0.65.

To find : What is the probability of someone's height being anywhere from 60 inches to 70 inches?

Solution :

The probability percentage of a curve is defined  as the area under the density curve as

P=\int\limits^a_b {e^{f(x)}} \, dx =A

The area under the density curve from 60 inches to 70 inches is 0.65.

So,The probability is equal to the area = 0.65

Therefore, The probability of someone's height being anywhere from 60 inches to 70 inches is 65%.

Hence, Option B is correct.

Convert both 1/5 and 1/4 to 20ths to get 4/20 and 5/20. From there just add the two together getting 9/20 of the trip done and 11/20 to go. Hope this answers your questions.

If a bird is on the ground, 7 ft away from a 10 ft tall tree, then what is the angle (to the
iren2701 [21]

Answer:

The angle is 55°

Step-by-step explanation:

To find the angle at which a bid is looking up on top of a tree that is 10feet tall if the bird is on the ground 7 feet away from the tree, we will follow the steps below:

we will use trigonometric ratio to find the angle

SOH CAH TOA

sinФ = opposite / hypotenuse

cosФ = adjacent / hypotenuse

tanФ = opposite /adjacent

from the diagram below, opposite = 10 feet   and   adjacent = 7 feet

the best trig.ratio to use is tan

tanФ = opposite /adjacent

tanФ = 10 /7

tan Ф =1.42857

to get the value of  Ф, we will take the tan⁻¹  of both-side

tan⁻¹ tan Ф = tan⁻¹ 1.42857

Ф= tan⁻¹ 1.42857

Ф≈55°

Therefore, the angle is 55°
