A newsletter publisher believes that 30% of their readers own a Rolls Royce. A testing firm believes this is inaccurate and performs a test to dispute the publisher's claim. After performing a test at the 0.02 level of significance, the testing firm fails to reject the null hypothesis. What is the conclusion regarding the publisher's claim
Answer:
The evidence is not sufficient at the 0.02 level of significance to reject the claim that the percentage is 30%.
Step-by-step explanation:
Let's first state the null and alternative hypotheses for this research;
H0: p = 0.30
Ha: p ≠ 0.30
Now, since the bull hypothesis is the claim and he fails to reject the null hypothesis from the research, we will conclude that;
The evidence is not sufficient at the 0.02 level of significance to reject the claim that the percentage is 30%.

Tommy has a rectangular-shaped swimming pool. He wants to know the volume of water in the pool, but he is not sure what the width of the
pool is. He knows the relationship between the width and the length and height of the pool. He used this relationship to come up with the
following equation to find the volume of the pool when the width is w meters.
A. Z
B. X
C. Y
D. W
Answer:
it is x
Step-by-step explanation:
The volume of a shape is the amount of space in it.
The graph that satisfies the above condition is the (b) graph X:
The volume of a rectangular-shaped swimming pool is
[tex]\mathbf{V=l \times w \times h}[/tex]
Where:
[tex]\mathbf{l,w,h \ge 0}[/tex] ---all the dimensions are greater than 0
[tex]\mathbf{l,w,h \ge 0}[/tex] means that:
The graph of V must have three x interceptsThe graph of V must not pass through the origin (0,0)From the given graphs, the graph that satisfies the above condition is the graph X:
This is so because it crosses the x-axis three times, and it does not pass through the origin

You are playing a game with your friend to see who can make the most baskets from the free-throw line. Each of you has 5 shots at the basket. How many ways are there for you to make exactly 4 shots?
A) 4
B) 5
C) 10
D) 6
Answer:
B) 5
Step-by-step explanation:
The given parameters are;
The number of shots at the basket = 5 shots
The number of ways to make exactly 4 shots is given by combination as follows;
The number of ways to shoot exactly 4 shots = ₅C₄ = 5!/(4!×(5 - 4)!) = 5
The number of ways to shoot exactly 4 shots = 5 ways
At the beginning of the school year, Liya's goal was to earn an A on
at least 85% of her 60 quizzes for the year. She earned an A on 35 of the first 40
quizzes. If she is to achieve her goal, on at most how many of the remaining
quizzes can she earn a grade lower than an A?
A: 1
B: 2
C: 3
D: 4
E: 5
Answer:
4
Step-by-step explanation:
If 15% of quizzes don't have to be A's, that means that its 9 quizes that can be lower than an A. She already lost 5 which means she has four left.
Answer:
D; 4
Step-by-step explanation:
Step 1:
Let us figure out exactly how many As Liya has to earn for the year. We must find 85% of 60:
[tex]85 \%\ of\ 60=\\\frac{85}{100}*\frac{60}{1}=\\\frac{85}{5} *\frac{3}{1} =\\17*3=\\51[/tex]
Liya must earn 51 As this year to reach her goal. This also means that she can earn 9 grades lower than an A to still reach her goal ([tex]60-51=9[/tex]).
Step 2:
So far, Liya has earned 35 As out of 40 tests in total. This means that so far, Liya has earned 5 test grade lower than an A:
[tex]40-35=5[/tex]
In total, Liya can only have 9 grades lower than an A. Therefore:
[tex]9-5=\fbox{4}[/tex]
Liya can only earn [tex]\fbox{4}[/tex] grades lower than an A in the remaining quizzes.

Answer:
c(x) = 16x + 22736
R(x) = -2x^2 + 524x
[ -2x^2 + 508x - 22736] = 0
Factored: f(x) = -2(x - 196)(x - 58)
58 to break even
Step-by-step explanation:
Your cost is the amount it cost you to "make" stuff.
You have fixed and variable costs (cost of oven is fixed cost of flower and sugar is variable to make cupcakes)
your cost is c(x) = 16x + 22736
"your oven and building cost $22736 per month and you use $16 worth of sugar butter flour to make one cupcake ( it must be a huge one) ...
your revenue is the amount of money that "comes into your business"...
the amount of money in the cash register.... Note: this is only money IN you still have to pay for the building, sugar flour etc.
R(x) = -2x^2 + 524x
Note: the minus and the square basically say that the more you charge the less cupcakes you will sell...
Profit is the money in minus the money out
P - R - E [ -2x^2 + 524x ] - [16x + 22736]
the break even point is where the two functions are the same
in other words where C=R or R-C=0
[ -2x^2 + 524x ] = [16x + 22736]
[ -2x^2 + 508x - 22736] = 0
Factored: f(x) = -2(x - 196)(x - 58)
Answer:
Step-by-step explanation:
C(x)=16x+22736
R(x)=-2x²+524x
P(x)=R(x)-C(x)
=-2x²+524x-16x-22736
=-2x²+508-22736
when profit is zero then no gain or loss.
so -2x²+508x-22736=0
or x²-254x+11368=0
196+58=254
196×58=11368
x²-54x-196x+11368=0
x(x-54)-196(x-54)=0
(x-54)(x-196)=0
x=54,196
so x=54 is the smallest number of bins to break even.

X =12
Step-by-step explanation:
Supplementary Angels means the angles are added up to 180 degrees.
So , <1 + <2 = 180
Given that,
<1 = 2x +6
Now lets find the size of <2.
We know that,
Angles in a Straight line is also added up to 180 degrees.
So,
<2+ < 3 = 180
Let's Solve.
[tex] < 2 + < 3 = 180 \\ < 2 +( 3x - 6) = 180 \\ < 2 = 180 - (3x - 6) \\ < 2 = 180 - 3x + 6 \\ < 2 = 186 - 3x[/tex]
Now we know the size of <2
lets find out the value of x
[tex] < 1 + < 2 = 180 \\ 2x + 6 + 186 - 3x = 180 \\ 186 + 6 - 180 = 3x - 2x \\ 12 = x[/tex]
Let's check whether the answer is correct.
We know that <1 =<3 (Alternative Angles)
[tex] < 1 = < 3 \\ 2x + 6 = 3x - 6 \\ 2 \times 12 + 6 = 3 \times 12 - 6 \\ 24 + 6 = 36 - 6 \\ 30 = 30[/tex]

Represent -2/11, -5/11, -9/11 on a number line.
Answer:
-9/ 11 ____-5/11 _____ - 2/11
Step-by-step explanation:
-2/11, -5/11, -9/11
All the numbers are negative ; the fraction which is largest is 9/11 ; then 5 /11 ; then 2 /11 ; however, since they are negative, they largest fraction becomes the least value.
Numbers on a number line are arranged from least to highest. Hence the numbers will be arranged in a number line as follows :
-9/ 11 ____-5/11 _____ - 2/11

A map of an island is shown on a half-centimeter grid,
where A, B, and Care houses.
The actual distance between A and B
is 960 meters.
a) Work out the scale on the map
Give your answer as 1:n
Answer:
The answer is below
Step-by-step explanation:
A map can either be scaled up or scaled down. If the map is enlarged then it is scaled up and hence represented by n:1, where n > 1. While is the map is reduced, it is scaled down and is represented by 1 : n, where n < 1.
Since one box has a length of 1 cm by 1 cm. The distance between A and B is 4 boxes = 4 cm = 0.04 m
Hence the scale is given as 1:n, where n > 1. n is gotten from:
n = 960 m / 0.04 m = 24000
Therefore the scale is 1 : 24000
Answer:
1:48000
Step-by-step explanation:
