Math need help. K12 I don’t understand. Book and lesson no help
REY [17]

Answer:

Figure 3

Figure 1

Step-by-step explanation:

Figure 1 is the pre-image

The side length is 2.  We multiply the side length by the scale factor.

2 * 4 = 8

The new figure will have a side length of 8.  That will be Figure 3

Figure 2 is the pre-image

The side length is 4.  We multiply the side length by the scale factor.

4 * 1/2 = 2

The new figure will have a side length of 2.  That will be Figure 1

How do I write an inequality?
g100num [7]
It is a lot like an equation but instead of and equal sign you put < > ≤ or ≥

For example

X>5 says x is greater than five. Meaning this is only true when x is any number larger than 5 like 7 but not 2.

Let me know if you need more help

PLS ANSWER QUICK LOL
Setler [38]

(3j, 3k) and (3/j, 3k)

So if their x values have the same signs and their y values have the same signs, they are in the same quadrant.

If j is negative, both 3j and 3/j would be negative. If j is positive then both 3j and 3/j are positive.

And 3k is the same as 3k.

An airliner carries 150 passengers and has doors with a height of 78 in. Heights of men are normally distributed with a mean of
iogann1982 [59]

Answer:

Step-by-step explanation:

x, height of men is N(69, 2.8)

Sample size n =150

Hence sample std dev = \frac{2.8}{\sqrt{150} } =0.229

Hence Z score = \frac{x-69}{0.229}

A) Prob that a random man from 150  can fit without bending

= P(X<78) = P(Z<3.214)=1.0000

B) n =75

Sample std dev = \frac{2.8}{\sqrt{75} } =0.3233

P(X bar <72) = P(Z<9.28) = 1.00

C) Prob of B is more relevent because average male passengers  would be more relevant than a single person

(D) The probability from part (b) is more relevant because it shows the proportion of flights where the mean height of the male passengers will be less than the door height.
