Twice the sum of a number and 7 is equal to three times the difference of the number and 8. Find the number.
Answer:
the number is 10.
Step-by-step explanation:
2(x + 7) = 3(x - 8)
2x + 14 = 3x - 24

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.

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]

Subtract the minimum value from the maximum value of each group's big box on the graph to get their IQR's
Suppose a normal distribution has a mean of 222 and a standard deviation of
16. What is the probability that a data value is between 206 and 230? Round
your answer to the nearest tenth of a percent.
A. 91.0%
B. 66.9%
C. 53.3%
D. 84.0%
Answer:
C) 53.3%
The probability that a data value is between 206 and 230
P( 206 ≤X≤230) = 0.5328 = 53.3%
Step-by-step explanation:
Explanation
Given that Mean of the Normal distribution(μ) = 222
Given that the standard deviation of the Normal distribution (σ) = 16
Let 'X' be the random variable in the Normal distribution
we have to find that the probability that a data value is between 206 and 230
solution:-
Step(i):-
Let 'X' = 206
[tex]Z = \frac{x^{-}-mean }{S.D} = \frac{206-222}{16} = -1[/tex]
Let X = 230
[tex]Z = \frac{x-mean }{S.D} = \frac{230-222}{16} = 0.5[/tex]
Step(ii):-
The probability that a data value is between 206 and 230
P( 206 ≤X≤230) = P( -1≤Z≤0.5)
= |A(0.5)+A(-1)|
= 0.1915+0.3413
= 0.5328
final answer:-
The probability that a data value is between 206 and 230
P( 206 ≤X≤230) = 0.5328 = 53.3%

Answer:
12
Step-by-step explanation:
Pythagoras Theorem is clearly used in this question.
To Calculate the Hypotenuse:
C = [tex]\sqrt{a^2+b^2}[/tex]
The Adjacent angle has already given as 9, so you can factor that into the question.
In Order to calculate the Opposite angle you need to use the following formula.
[tex]b = \sqrt{c^2-a^2}[/tex]
With the integers we already have for both Hypotenuse and Adjacent factored in this will be your equation:
[tex]b = \sqrt{15^2-9^2} = 12[/tex]
Therefore you answer is 12, Hope this helps, feel free to make as brainilest.
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

One of the angles in an isosceles triangle is 74°.
What could the other two angles be?
Answer:
we know that isoceles has pair of angle with same measurement and sum of interior angle of triangle is 180°
Step-by-step explanation:
Let other angle be x
x+x+74°= 180°
=> 2x = 180°-74°
=>x = 106°/2
=> x= 53°
If one of the angles in an isosceles triangle is 74°. Then the other two angles will be 53°.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
In an isosceles triangle, two angles and their opposite sides are equal.
One of the angles in an isosceles triangle is 74°.
Let the other angle be x.
Then the value of x will be
x + x + 74° = 180°
2x = 180° – 74°
2x = 106°
x = 53°
