Explain how you used the bar model in exercise 2 to solve the problem
lutik1710 [3]

We are given that Grandma has 14 red roses and 7 pink roses.

In order to represent them on bar modal, we need to make a bar with 14 identical sections for 14 red roses.

And for pink roses, we need to make a bar with 7 identical sections for 7 pink roses.

<em>From the bar graph, we can see that bar for red roses have 7 more boxes than bar of pink roses.</em>

<h3>Therefore,  she have 7 more red roses than pink roses.</h3>

love history [14]

Answer:

From the Pythagorean Theorem we know:

hypotenuse^2 = side^2 + side^2

hypotenuse^2 = 36 + 36

hypotenuse = square root (72)

hypotenuse = 8.48528... feet

Crackers come in packages of 24. Cheese slices come in packages of 18. Andy wants one cheese slice for each cracker. Patrick mad
ANEK [815]

Patrick's statement is incorrect.

Explanation:

Crackers come in package of = 24

Cheese slices come in package of = 18

As given, Andy wants one cheese slice for each cracker so we will find the least common multiple of 24 and 18.

The L.C.M is 72.

So, Andy needs 72 crackers and 72 cheese slices.

Number of cracker packages needed=\frac{72}{24}=3

Number of cheese slice packages needed=\frac{72}{18}=4

Hence, Patrick's statement is incorrect. Andy needs 3 packages of crackers and 4 packages of cheese slices to make them even.

A soda factory has a special manufacturing line to fill large bottles with 2 liters of their beverage. Every process is computer
Drupady [299]

Answer:

z= \frac{2.1-1.98}{0.08}= 1.5

And we can use the normal standard table and the complement rule and we got:

P(z>1.5)= 1-P(Z

And the best answer would be:

C 0.07

Step-by-step explanation:

Let X the random variable who represent the amount of soda filled in large bottles and we know this:

\mu = 1.98, \sigma =\sqrt{0.0064}= 0.08

And we want to find this probability:

P(X> \mu +1.5 \sigma = 1.98 +1.5*0.08 =2.1)

And for this case we can use the z score formula given by:

z=\frac{X -\mu}{\sigma}

And replacing we got:

z= \frac{2.1-1.98}{0.08}= 1.5

And we can use the normal standard table and the complement rule and we got:

P(z>1.5)= 1-P(Z

And the best answer would be:

C 0.07
