The total possibilities is still 4.
H H
H T <<<< 
T H <<<<
T T

The two that work are marked with <<<<

H T = 1/3 * 2/3 = 2/9
T H = 2/3 * 1/3 = 2/9



The total is 2/9 + 2/9 = 4/9
We should check this
1 heads = 4/9
2 heads = 1/9
2 tails = 4/9
4/9 + 4/9 + 1/9 = 1 It checks

Figure B is misleading because " vertical scale doesn't start with zero"

Step-by-step explanation:

Given are the two bar graphs to compare the sales of two theatres.

The x-axis has types of movies and y-axis has sales.

We can see that the scale of Figure A on y-axis starts from zero while the scale of figure B starts from 50. The both graphs cannot be compared with this scale.

Hence,

Figure B is misleading because " vertical scale doesn't start with zero"

Which of the following combined with the equation −9x + 3y = 12 creates a system of linear equations with no solution?
PolarNik [594]
ANSWER

The correct answer is option A

EXPLANATION

A line that will create a system of equation with no solution when combined with
- 9x + 3y = 12
,is the line that has the same slope as
- 9x + 3y = 12
but different y-intercept.

So, let us write the given equation in slope intercept form to obtain,

3y = 9x + 12

\Rightarrow \: y = 3x + 4

The slope is
3
and y-intercept is
4.

Now let us determine the slope and intercept for the given options too.

For option A,

18x - 6y = 20

\Rightarrow \: - 6y = - 18x + 20

\Rightarrow \: y = 3x - \frac{10}{3}

This has the same slope as the given equation but different y-intercept. When combined with the given equation, there will be no solution, since the two lines will never intersect. so it is the correct option.

For option B,

3x - y = - 4

\Rightarrow \: -y = - 3x - 4

\Rightarrow \: y = 3x + 4

This option has the same slope and y-intercept as the given line so when combined with this equation, there will be infinitely many solution.

As for option C and D they do not have the same slope as the given line so there will be a unique solution when each is combined with the given line.

Joe works mowing lawns and babysitting. He earns $9.10 an hour for mowing and $7.90 an hour for babysitting. How much will he ea
kirill115 [55]

Answer:

Joe would receive $9.10 for One hour of mowing the lawn and $39.50 for Five hours of babysitting, which (if needed) adds up to $48.60

Step-by-step explanation:

It's as simple as multiplication. Since he only mowed the lawn for one hour, it would only be $9.10. Since he babysat for 5 hours, you'd simply multiply $7.90 by five, giving you the answer $39.50
