Answer:

The dimensions of the enlarged poster are 6\ ft  by  15\ ft

Step-by-step explanation:

we know that

The scale factor is equal to the measure of the corresponding side of the enlarged poster divide by the the measure of the corresponding side of the original poster

Let

z-----> scale factor

x------> the measure of the corresponding side of the enlarged poster

y------> the measure of the corresponding side of the original poster

so

z=\frac{x}{y}

In this problem we have

z=\frac{3}{2}=1.5

Step 1

Find the length of the enlarged poster

x=zy

we have

z=1.5

y=10\ ft

substitute

x=1.5(10)=15\ ft

Step 2

Find the width of the enlarged poster

x=zy

we have

z=1.5

y=4\ ft

substitute

x=1.5(4)=6\ ft

therefore

the dimensions of the enlarged poster are 6\ ft  by  15\ ft

Choose the correct simplification of f^9 h^23/f^3 h^17
Tanzania [10]

Answer:

f6h40

Step-by-step explanation:

Step  1  :

           h23

Simplify   ———

           f3  

Equation at the end of step  1  :

         h23

 ((f9) • ———) • h17

         f3  

Step  2  :

Multiplying exponential expressions :

2.1    h23 multiplied by h17 = h(23 + 17) = h40

Final result :

 f6h40

Suppose that the probability that a person books an airline ticket using an online travel website is 0.72. Consider a sample of
ExtremeBDS [4]

Answer:

0.183

Step-by-step explanation:

This is a question on Binomial Probability

Formula =nCx × p^x × q^n - x

p = 0.72

q = 1 - p

= 1 - 0.72

= 0.28

x = number of successes = 9

n = 10

The probability that at least nine out of ten people used an online travel website when they booked their airline ticket

At least 9 out of 10 means

x ≥ 9 = x = 9 and x = 10

Hence,

P(x ≥ 9) = 10C9 × (0.72^9 × 0.28^10 - 9) + 10C10 × ( 0.72^10 × 0.28^10 - 10)

P(x ≥ 9) = 0.14559635388 + 0.0374390623

= 0.18303541631

≈ 0.183

1. copying

4. ridgid motion

5. Distance Formula

6. image

7. transformation

8. translation

I don't really know if these are correct because I have never had to define any of those words or know a lot of these. But some of them I am pretty sure are right. I hope I helped some. I am sorry if I didn't. But this is my best guess.
