If two fair dice are rolled what is the probability that the sum of the dice is 10, given the sum is greater than 4

1 answer:

7 0

Sum is 10 = (4, 6), (5, 5), (6, 4) = 3
sum is greater than 4 = 30
<span>P(the sum of the dice is 10 | the sum is greater than 4) = 3/30 = 1/10</span>

Liliana is making a vase with a circular base. She wants the area of the base to be between 135 cm2 and 155 cm2. Which circle co

Umnica [9.8K]

Answer:

(b) Circle C is shown. Line segment A C is a radius with length 7 centimeters.

Step-by-step explanation:

Given

$Minimum\ Area = 135cm^2$

$Maximum\ Area = 155cm^2$

$\pi = 3.14$

Required

Which circle could she use

To do this, we simply calculate the areas of all the given circles

The area of a circle is:

$Area = \pi r^2$

Where

$r = radius$

$a.\ r = 6cm$

The area is calculated as thus:

$Area = \pi r^2$

$Area = 3.14 * (6cm)^2$

$Area = 3.14 * 36cm^2$

$Area = 114.04cm^2$

$b.\ r = 7cm$

The area is calculated as thus:

$Area = \pi r^2$

$Area = 3.14 * (7cm)^2$

$Area = 3.14 * 49cm^2$

$Area = 153.86cm^2$

$c.\ r = 8cm$

The area is calculated as thus:

$Area = \pi r^2$

$Area = 3.14 * (8cm)^2$

$Area = 3.14 * 64cm^2$

$Area = 200.96cm^2$

$d.\ r = 9cm$

The area is calculated as thus:

$Area = \pi r^2$

$Area = 3.14 * (9cm)^2$

$Area = 3.14 * 81cm^2$

$Area = 254.34cm^2$

<em>From the calculations above; only the circle in option (b) has an area within the required range of 135 to 155cm^2</em>

Which of these strategies would eliminate a variable in the system of equations? 8x+8y=2 8x+5y=1 Add the equations. (Choice B

harkovskaia [24]

Answer:

B. Subtract the bottom equation from the top equation.

Step-by-step explanation:

When looking at the two equations:

8x + 8y = 2

8x + 5y = 1

We can easily get rid of the x variable by subtracting the two equations from each other since the terms are equivalent. This would allow us to solve for the y value, which we could plug into the an equation to solve for the x value.

Which is the best linear model for the data shown in the scatter plot?

Studentka2010 [4]

The best linear model for the data that's illustrated will be y = 10x + 5

<h3>What is a linear model?</h3>

It should be noted that a linear model simply means model where the terms are added. It should be noted that this can be used in connection with the regression model.

Here, the best linear model for the data will be:

= (10 × x) + 5

= 10x + 5

Therefore, the best linear model for the data that's illustrated will be y = 10x + 5.
