Answer:

y ----→  <u>-1</u> , 1 , <u>3</u> , <u>5</u> , 7 , <u>9</u>

Step-by-step explanation:

<u>LINEAR EQUATION GIVEN IN THE QUESTION</u> :-  y = 2x + 3

In the question , some values of variable 'x' are given. Lets put each value of 'x' in the equation.

  • When x = -2 ;  y = 2(-2) + 3 = -4 + 3 = -1
  • When x = -1 ; y = 2(-1) + 3 = -2 + 3 = 1
  • When x = 0 ; y = 2(0) + 3 = 0 + 3 = 3
  • When x = 1 ; y = 2(1) + 3 = 2 + 3 = 5
  • When x = 2 ; y = 2(2) + 3 = 4 + 3 = 7
  • When x = 3 ; y = 2(3) + 3 = 6 + 3 = 9

Thus , we got all the required values of y.

Chris mixes 4cups of cereal 3cups of pecans 2 cuos of raisins how can you use ratios to compare quantities of each ingredient an
andrew11 [14]

Answer:

cereal : pecans : raisins = 2 : 1.5 : 1

Step-by-step explanation:

Given:

The amount of cereal in snack mix = 4 cups

The amount of pecans in snack mix = 3 cups

The amount of raisins in snack mix = 2 cups

Therefore,

The total amount of snack = 4 cups + 3 cups + 2 cups = 9 cups

Now,

The ratio is given as:

= \frac{\textup{Amount of a substance in a mix}}{\textup{Total amount of mix}}

therefore,

Ratio of cereal in snack mix = \frac{\textup{4 cups}}{\textup{9 cups}}

and,

Ratio of pecans in snack mix = \frac{\textup{3 cups}}{\textup{9 cups}}

Ratio of raisins in snack mix = \frac{\textup{2 cups}}{\textup{9 cups}}

Now,

we have ratio as:

4 : 3 : 2

i.e cereal : pecans : raisins

taking 2 common

we get

2 : 1.5 : 1

therefore,

the maximum amount

You have just used the network planning model and found the critical path length is 30 days and the variance of the critical pat
ollegr [7]

Answer: The probability that the project will be completed in 33 days or less is equal to<u> </u><u>0.73</u> .

Step-by-step explanation:

We assume that this is a normally distribution.

Given : The critical path length is 30 days .

i.e. Population mean = \mu=30

Variance : \sigma^2=25

Then, standard deviation : \sigma=\sqrt{25}=5

Z-score :  z=\dfrac{x-\mu}{\sigma}

The value of z corresponding to 33 = z=\dfrac{33-30}{5}=0.6

Now, the p-value = P(x\leq33)=P(z\leq0.6)=0.7257469\approx0.73

Hence, the probability that the project will be completed in 33 days or less is equal to 0.73.
