Answer:1/10

Step-by-step explanation:so easy

The probability that the students she selects are both boys is 1/10.

Given is that a math class has 4 girls and 1 boy in the seventh grade and 5 girls and 5 boys in the eighth grade. The teacher randomly selects a seventh grader and an eighth grader from the class for a competition.

The probability that the students she selects are both boys -

P{E} = P{1} x P{2}

P{1} : randomly selecting a seventh grader as a boy.

P{2} : randomly selecting a eight grader as a boy.

We can write -

P{1} = n{f}/n{s} = 1/5

P{2} = n{f}/n{s} = 5/10 = 1/2

P{E} = P{1} x P{2}

P{E} = 1/5 x 1/2

P{E} = 1/10

Therefore, the probability that the students she selects are both boys is 1/10.

The more convenient method to solve the given system of equations is by elimination.

From the question, we are to determine whether it would be more convenient to solve the system of equations by substitution or elimination

The given system of equations is

2 = 4y - 10     ----------- (1)

7x +12y = 7    ----------- (2)

In equation (1), we can see that there is no variable x in the equation. Thus we can solve for y and then substitute the value of y into equation (2).

That is,

From equation (1)

2 = 4y - 10

2 + 10 = 4y

12 = 4y

12/4 = 4y/4

3 = y

∴ y = 3

Now, we can substitute the value of y into equation (2) to determine the value of x

Hence, the more convenient method to solve the given system of equations is by elimination.

Step-by-step explanation:

the price of:

3.17 pounds of pears = 3.17 × 0.99

= $3.14

1.45 pounds of oranges = 1.45 × $1.19 = $1.73

1.77 pounds of grapes = 1.77 × $1.29 =$2.28

so , the total bill = 3.14+ 1.73+ 2.28 = $7.15

Find prices of all

Answer:

94  boys and 56 girls.

Step-by-step explanation:

150/8 = 18.75 = x

b=x*5 = 94

g=x*3 = 56

b+g=150

Looking at the question, we see that the ratio of boys to girls is 5:3, the total is 8. We are trying to find what the ratio of boys to girls is while the total is 150. Now, we can easily divide 150 by 8, finding one part of our answer! 150 ÷ 8 ≈ 18 [tex]\frac{3}{4}[/tex]. now to multiply that by the amount of boys and girls (5:3), 18 [tex]\frac{3}{4}[/tex]  × 5 = 93  [tex]\frac{3}{4}[/tex]  and 18 [tex]\frac{3}{4}[/tex] × 3 =  56 [tex]\frac{1}{4}[/tex]. After we round we get 94:56.

Answer:

Table 1 (leftmost)

Step-by-step explanation:

A linear function has a common difference between all of the x-values. This means that all the x-values change by the same amount relative to the change in y. In this case, the x-value increases by 1/2 every time that y increases by 1. The other tables do not work because their change is inconsistent. There is no number being added each time. Therefore, they are not linear. If you were to graph these tables, only table 1 would make a straight line.

Answer:

  g(x) = √(x -5) +7

Step-by-step explanation:

To translate the graph of f(x) by h units horizontally and k units vertically, the function is transformed to ...

  g(x) = f(x -h) +k

To translate f(x) = √x by 5 units horizontally and 7 units vertically, the function is transformed to ...

  g(x) = √(x -5) +7

Answer:

Step-by-step explanation:

While I can not give you the exact answer as it is a graph, it's worth noting that the function is in f(x) = mx + b form.

This means the first point with an x coordinate of 0 will start at 6, and for each increase in one on the x-axis, we add 2.4.

So, the first coordinate is (0,6), the next is (1,8.4), and so on until you reach the end. That shouldn't take very long provided you can compute addition mentally.
