What is the surface area of this right rectangular prism?

tiny-mole [99]

Answer:

32 yd^2

Step-by-step explanation:

Ignore rounded approximations (i.e. 2.66, 1.33). For all calculations, use fractions and EXACT values.

This prism has 6 surfaces:

Front: 3 x 2.66 = 8
Back: 3 x 2.66 = 8
Top: 3 x 1.33 = 4
Bottom: 3 x 1.33 = 4
Side: 1.33 x 2.66 = 4
Side: 1.33 x 2.66 = 4

Total SA: 8(2) + 4(4) = <u>32 yd^2</u>

In a large population, about 10% of people do not like the taste of cilantro, an herb used in cooking. A researcher takes a rand

bogdanovich [222]

Answer:

0.0019390

Step-by-step explanation:

10% of people do not like the taste of cilantro

A researcher takes a random sample of 15 people and surveys whether they like cilantro

Use the binomial distribution to compute the probability that exactly 6 of the people in the sample do not like cilantro.

Probability of success = 0.10 = p

Probability of failure = 0.9 =q

n = 15

r = 6

Formula : $P(X=r)=^nC_rp^r q^{n-r}$

$P(X=6)=^{15}C_6 (0.1)^6 (0.9)^{15-6}$

$P(X=6)=\frac{15!}{6!(15-6)!} (0.1)^6 (0.9)^{15-6}$

$P(X=6)=0.0019390$

Hence the probability that exactly 6 of the people in the sample do not like cilantro is 0.0019390

. Which equation represents the line that passes through the points (3.7) and (-1.-1)

kondaur [170]

Answer:

$y=2x+1$ or $y+1=2(x+1)$

Step-by-step explanation:

step 1

Find the slope of the line

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$A(3,7)\ B(-1,-1)$

Substitute the values

$m=\frac{-1-7}{-1-3}$

$m=\frac{-8}{-4}=2$

step 2

Find the equation of the line into slope point form

$y-y1=m(x-x1)$

we have

$m=2$

$pointB(-1,-1)$

substitute

$y+1=2(x+1)$ -----> equation of the line into point slope form

$y=2x+2-1$

$y=2x+1$ -----> equation of the line into slope intercept form

Please solve<br> 8.722÷(−3.56)

melomori [17]

Answer:

-2.45

Step-by-step explanation:

You are asked to EVALUATE 8.722÷(−3.56). Here you are dividing a positive number by a negative one, and so you expect that the result (quotient) will be negative.

Thus, 8.722÷(−3.56) becomes -8.722÷(3.56) = -2.45
