Answer: I'm pretty sure it's 150.
Step-by-step explanation:
I need help with this. Mostly just 2a and 2b.
2a. A(t) = π(70 + 6t)^2 (Let t = 2 hours)
A(2) = π(70 + 6(2))^2 = 6724π
Now let t = 0 hours (result from part 1)
A(t) = π(70 + 6(0))^2 = 4900π
Average rate = 6724π - 4900π/2-0 = 912π
912π area covered per hour
2b. Let t = 1/2 hours, A(t) = π(70 + 6(1/2))^2 = 5329π,
Let t = 0 hours - result from last time was 4900π,
Average rate = 5329π - 4900π/1/2 - 0 = 858π
858π area covered per hour

Group A IQR = $700
Group B IQR = $400
Group A's IQR is Greater Than Group B's IQR, so the salaries in the middle 50% for Group A are More spread out than those for Group B.
Step-by-step explanation:
Subtract the minimum value from the maximum value of each group's big box on the graph to get their IQR's
Joe asked the children in his class which flavours of ice-cream they like.
He recorded the results in a Venn diagram.
How many children like chocolate ice-cream?
Answer:
a. 19
b. 14
Step-by-step explanation:
From the venn diagram, we see that:
9 children like only Vanilla
7 like vanilla and chocolate
12 like only chocolate, and
2 like neither chocolate nor vanilla
Thus:
a. Number of children that liked Chocolate ice-cream = those that like chocolate only + those that like both chocolate and vanilla = 12 + 7 = 19
19 children like chocolate ice-cream.
b. Number of children who do not like Vanilla ice-cream = those that like chocolate only + those that do not like neither chocolate nor vanilla = 12 + 2 = 14
14 children do not like vanilla ice-cream.

if the cube was Rolled 78 x and the nine appears 26 times what was the experimental probability of rolling a 9
Answer:
1/3 = 0.3333 = 33.33% experimental probability of rolling a 9.
Step-by-step explanation:
The experimental probability is given by the number of desired outcomes divided by the number of total outcomes, after a number of experiments is made.
In this question:
Cube rolled 78 times.
9 appeared 26 times
26/78 = 1/3 = 0.3333 = 33.33% experimental probability of rolling a 9.

A circles diameter is 10 yards what is the circles area using 3.14
Answer:
[tex]78.5yd^{2}[/tex]
Step-by-step explanation:
The formula to find the area of a circle of is: A = [tex]\pi r^{2}[/tex]
However, the question wants to use 3.14 instead of pi.
We need to find the radius. The radius of the circle is half the diameter. So, the radius to 5 yards.
Now we just plug in the formula.
[tex]A=3.14*(5yd)^{2} \\A=3.14*25yd^{2} \\A=78.5yd^{2}[/tex]

Find the value of the discriminant of the following equation 10x² + x = 1.
Answer:
41
Step-by-step explanation:
as discriminant is b^2 -4ac
b= 1
a= 10
c = -1
then
1^2 - (4*10*-1) = 1 - (-40) = 1 + 40 = 41
David had a coupon for the grocery store. He graphed on the x-axis what his total bill would be if he didn’t use the coupon and graphed on the y-axis what his total bill would be if he used the coupon.
Grocery Bill
A graph has bill without coupon on the x-axis and bill with coupon on the y-axis. A line goes through points (2, 0) and (3, 1).
Based on the information in the graph, if David’s bill came to $66 after the coupon was applied, how much would his bill have been if he hadn’t used the coupon?

It is possible, through careful consideration of economic principles and interactions, to reach a state of equilibrium in practice.
Please select the best answer from the choices provided
T
F
Answer: False
Step-by-step explanation:
Economic equilibrium simply refers to a scenario where the economic forces are equal and balanced. It is the condition whereby the demand and the supply of goods and services are equal.
We should note that economic equilibrium is only theoretical. In reality, this isn't true as the market doesn't reach equilibrium, Eben though it moves towards it.
Therefore, the statement in the question is false.
Answer:
False
