Answer:
y>= 2/3(x) - 2.5
Step-by-step explanation:
The sign should be "greater than or equal to" but my keyboard doesn't have that. Sorry.
The slope is "up two, over three" found by finding places where the line passes through the grid lines, and counting.
The y-intercept is -2.5. That tells you the "constant" to put in for "b" in the slope intercept form, y=mx+b
Pretty sure the answer is D:
Because the equation is in the format y=mx+c (c being the y intercept), we know that the y intercept (or where the line will cross the y axis) will be -9.
B also says -9 but we have to be careful because it states that the x axis is -9 rather than the y axis.
Hope that helped you understand.
The probability of both children receiving a tablet is 15%.
We have given that
Age of Children P(Tablet) P(Laptop)
Less than 10 0.3 0.02
10-17 0.5 0.4
<h3>What is the probability?</h3>
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Probability of both children receiving a tablet is
0.3*0.5 = 0.15 = 15%
Therefore, the probability of both children receiving a tablet is 15%
Therefore option b is correct.

Answer:
1. B
2. D
3. B
4. D
5. C
6. A
7. What is the estimated sum of "?" what are we estimating?
8. C
9. C
10. B
Step-by-step explanation:
1st question
1/4 ≤ 8/19 ≤ 3/4, so round it to 1/2.
1/4 ≤ 6/13 ≤ 3/4, so round it to 1/2.
Estimating:
1/2 + 1/2 = 1
2nd question
220 9/11 divided by 6 19/20 = 2.99542184434
Rounded/estimated = 3
3rd Question
Estimate 8 1/8 (common sense)
8 1/8 = 8.
4th Question
Assuming cups = 2.
2x24 = 48.
5th Question
3
6th Question
Add and estimate
7th question
What is the estimated sum of "?" what are we estimating?
8th question
6/7 > 3/4, so round it to 1.
1/4 ≤ 4/7 ≤ 3/4, so round it to 1/2.
Estimating:
1 + 1/2 = 1 1/2
9th Question
Round 7 to 8. It is over half, so it would be 8, which = 1
10th Question
Half of 20 = 10, 9 isn't above 10.
So round backwards to 24.
Answer:
Step-by-step explanation:
An exponential equation has the form
y=ar^x where y=final value, a=initial value, r=rate, and x=time, in this case
y=28000(0.73^x)
So the initial value is 28000 and r=0.73. Since 0.73 is less than one this is an exponential decay representing a 27% loss per year. So B and F are correct.
