Answer:

The answer is 2 and 8

Step-by-step explanation:

First let us find the value of 8*4

8*4 = 32

Second let us find two numbers that we can correctly multiply to give half of 32 I.e 16.. Say 8 and 2

Hence 8*2=16

So that when we double 16 we have 32

I.e

16*2=32

The director of admissions at Kinzua University in Nova Scotia estimated the distribution of student admissions for the fall sem

Naily [24]

Answer: 1406

Step-by-step explanation:

Given Table :

Admissions Probability

1,040 0.3

1,320 0.2

1,660 0.5

Now, the expected number of admissions for the fall semester is given by :-

$E(x)=p_1x_1+p_2x_2+p_3x_3\\\\\Rightarrow\ E(x)=0.3\times1040+0.2\times1320+0.5\times1660\\\\\Rightarrow\ E(x)=1406$

Hence, the expected number of admissions for the fall semester = 1406

If the tan of angle x is 22/5 and the triangle was dilated to be two times as big as the original, what would be the value of th

KATRIN_1 [288]

Trigonometric values (sin, cos, tan etc.), represents the ratio between two sides.

In this case the triangle is dilated, which means the size will change but the shape will stay proportional.

Because the sides grew proportional their ratio stays the same; so, the tan in the second triangle is 22/5 too.

Moreover, because the sides grew/shrunk proportional, the angles stay the same.

Because same angles have the same trigonometric values, tan(x) in second triangle becomes 22/5.
