2/3 = 0.66
7/6 = 1.166
1/8 = 0.125
9/10 = 0.9

least to greatest : 2/3, 1/8, 9/10, 7/6

$slope = \frac{ - 5 - 4}{6 - 3} \\$

$slope = \frac{ - 9}{3} \\$

$slope = - 3 \\$

frozen [14]

Answer:

352 divided by 40 is 88

Step-by-step explanation:

lets put this in another form 352/40 so now you have 352 uh cheetos. You wanna share with your lunch table so you divide them into 40 groups. each person gets 88.

A particular brand of dishwasher soap is sold in three sizes: 25 oz, 45 oz, and 60 oz. Twenty percent of all purchasers select a

Verdich [7]

Answer:

(a) <u>Sampling distribution </u>

P(25) = 0,04

P(35) = 0.1 + 0.1 = 0,2

P(42,5) = 0.06 + 0.06 = 0,12

P(45) = 0,25

P(52,5) = 0.15 + 0.15 = 0,3

P(60) = 0,09

(b) E(X) = 45.5 oz

(c) E(X) = μ

Step-by-step explanation:

The variable we want to compute is

$X=(X1+X2)/2$

For this we need to know all the possible combinations of X1 and X2 and the probability associated with them.

(a) <u>Sampling distribution </u>

Calculating all the 9 combinations (3 repeated, so we end up with 6 unique combinations):

P(25) = P(X1=25) * P(X2=25) = p25*p25 = 0.2 * 0.2 = 0,04

P(35) = p25*p45+p45*p25 = 0.2*0.5 + 0.5*0.2 = 0.1 + 0.1 = 0,2

P(42,5) = p25*p60 + p60*p25 = 0.2*0.3 + 0.3*0.2 = 0.06 + 0.06 = 0,12

P(45) = p45*p45 = 0.5 * 0.5 = 0,25

P(52,5) = p45*p60 + p60*p45 = 0.5*0.3 + 0.3*0.5 = 0.15 + 0.15 = 0,3

P(60) = p60*p60 = 0.3*0.3 = 0,09

(b) Using the sample distribution, E(X) can be expressed as:

$E(X)=\sum_{i=1}^{6}P_{i}*X_{i}\\E(X)=0.04*25+0.2*35+0.12*42.5+0.3*52.5+0.09*60 = 45.5$

The value of E(X) is 45.5 oz.

(c) The value of μ can be calculated as

$\mu=\sum_{i=1}^{3}P_{i}*X_{i}\\\mu=0.2*25+0.5*45+0.3*60=45.5$

We can conclude that E(X)=μ

We could have arrived to this conclusion by applying

$E(X)=E((X1+X2)/2)=E(X1)/2+E(X2)/2\\\\\mu = E(X1)=E(X2)\\\\E(X)=\mu /2+ \mu /2 = \mu$

Which linear inequality is represented by the graph?

vodka [1.7K]

The correct answer is B. I figured this out by testing out coordinates into each equation. I am only going to show my work for equation B though... if you want to see the rest of my work, message me.

(0,0) ⇒ this point is within the shaded part of the graph

0 ≤ 1/2(0) + 3
0 ≤ 0 + 3
0 ≤ 3
True

(1,4) ⇒ this point is within the unshaded region

4 ≤ 1/2(1) + 3
4 ≤ 1/2 + 3
4 ≤ 3.5
False

This proves that equation B matches the graph shown.
