The daily attendance at a bowling alley was recorded for 15 days. The scatterplot
shows the number of lanes rented each day and the number of people who bowled
that day. Which statement is best supported by the sscatterplot?
HELP PLEASE :(
Answer:
I am gonna assume 4.
Step-by-step explanation:
As we can see the more people who rent out a lane, there are more people bowling.
The statement is best supported by the scatterplot is D. There is a positive linear association between the number of lanes rented and the number of people who bowl.
How does the dot plot work?Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in the number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing.
Given that daily attendance at a bowling alley was recorded for 15 days.
The scatterplot represents the number of lanes rented each day and the number of people who bowled that day.
By looking at the scatter plot graph we will have that there is a positive linear association between the number of lanes rented and the number of people who bowl.

A random sample of 20 married women showed that the mean time spent on housework by them was 29.8 hours a week with a standard deviation of 6.7 hours. If the margin of error is 3.14, find a 95% confidence interval for the mean time spent on housework per week by all married women.
Answer:
95% confidence interval for the mean time spent on housework per week by all married women.
( 26.66 , 32.94)
Step-by-step explanation:
Step(i):-
Given random sample size 'n' = 20
Mean of the sample (x⁻ ) = 29.8 hours
Standard deviation of the sample (S) = 6.7
Given Margin of error = 3.14
Step(ii):-
95% confidence interval for the mean is determined by
[tex](x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} +t_{0.05} \frac{S}{\sqrt{n} })[/tex]
We know that margin of error is determined by
[tex]M.E = \frac{t_{0.05}XS.D }{\sqrt{n} } = 3.14[/tex]
Now 95% confidence interval for the mean time spent on housework per week by all married women.
[tex](29.8 - 3.14 , 29.8+3.14)[/tex]

Answer:
x = 1/9
Step-by-step explanation:
we want to solve the proportion;
we simply cross multiply the values
Mathematically, that will be calculated as follows;
6x * 21 = 2 * 7
6x * 21 = 14
6x = 14/21
2(3x) = 2(7/21)
3x = 7/21
3x = 1/3
x = 1/3/3

Find the perimeter of triangle ABC. Approximate to the nearest whole unit.
Answer: 16 units
Step-by-step explanation: adding the perimeter sides to get the perimeter of triangle ABC would be 4.1+6.1+5.8 = 16
Answer:
16
Step-by-step explanation:
AC = 6.1
CB = 5.8
BA = 4.1
Use whole number approximations for the three side lengths.
AC = 6
CB = 6
BA = 4
perimeter = AC + CB + BA = 6 + 6 + 4 = 16
Answer: 16
Which point is a solution to this system of inequalities?
y ≤1/2x-3
y+2x greater than 6
A) (7,-8)
B) (2,-3)
C) (5,-2)
D)(4,1)
The point is a solution to this system of inequalities y ≤1/2x-3 and y+2x greater than 6 are B) (2,- 3) and D) (4,1).
To track down the answer for the arrangement of imbalances y ≤ 1/2x - 3 and y + 2x > 6, we want to test each answer decision to check whether it fulfills the two disparities.
A) (7,- 8):
y ≤ 1/2(7) - 3 = 0.5
y + 2(7) > 6
This point doesn't fulfill the primary imbalance, so it's anything but an answer.
B) (2,- 3):
y ≤ 1/2(2) - 3 = - 2
y + 2(2) > 6
This point fulfills the two imbalances, so it is an answer.
C) (5,- 2):
y ≤ 1/2(5) - 3 = - 0.5
y + 2(5) > 6
This point doesn't fulfill the main imbalance, so it's anything but an answer.
D) (4,1):
y ≤ 1/2(4) - 3 = - 1
y + 2(4) > 6
This point fulfills the two imbalances, so it is an answer.
Accordingly, the answers for the arrangement of imbalances are B) (2,- 3) and D) (4,1).
To track down the answer for the arrangement of disparities y ≤ 1/2x - 3 and y + 2x > 6, we really want to test each answer decision to check whether it fulfills the two imbalances. Just response decisions B) (2,- 3) and D) (4,1) fulfill the two imbalances, making them the arrangements.

Write an algebraic expression to represent the total number of candies and toys that Regina made for her birthday party.
Answer:
c + t = 13
Step-by-step explanation:
Regina originally packed 10 goodies bags for her birthday party. She found out the day before the party that a few more friends would be attending so she made three additional bags for the party. Write an algebraic expression to represent the total number of candies and toys that Regina made for her birthday party.
Let the number of candies = c
Let the number of toys = t
The total number of goodies bags she made = 10 + 3 = 13 goodie bags
Hence,
The total number of candies and toys that Regina made for her birthday party
c + t = 13
What is the inverse of the function f(x) = one-quarterx – 12?
Answer:
f^(-1)(x) = 4x + 48.
Step-by-step explanation:
Is suppose the function is f(x) = 1/4 x - 12
This is equivalent to the line y = 1/4 x - 12.
To get the inverse, change the x and y:
x = 1/4 y - 12
Now solve for y:
x + 12 = 1/4 y
y = 4x + 48
So the inverse f^(-1)(x) = 4x + 48.
Answer:
f-1(x) = 4x + 48.
Step-by-step explanation:
let f(x) = y = 1/4 x - 12
We solve for x:
y = 1/4 x - 12
1/4 x = y +12
Multiply through by 4:
x = 4y + 48
The inverse f-1(x) = 4x + 48.

3. A certain 50 cm spring will stretch (in
cm) the weight (in kg) attached to
it. How long will the spring be if a 35
kg weight is attached to it?
Complete Question
A certain 50 cm spring will stretch (in cm) one fifth the weight (in kg) attached to it. How long will the spring be if a 35 kg weight is attached to it
Answer:
The value is [tex]L_w = 57 \ cm[/tex]
Step-by-step explanation:
The length of the spring is [tex]L = 50 \ cm = 0.5 \ m[/tex]
The mass attached to it is [tex]w = 35 \ kg[/tex]
Generally given from that the spring will stretch one fifth of the weight (in kg)attached to it , it then means that the new length of the spring whenever a weight is attached to it is mathematically represented as
[tex]L_w = L + \frac{W}{5}[/tex]
=> [tex]L_w = 50 + \frac{35}{5}[/tex]
=> [tex]L_w = 57 \ cm[/tex]
