Answer:
There is enough evidence at the 0.05 significance level that the percentage is less than 25%.
Step-by-step explanation:
The question has no options. However, there are enough details to arrive at a conclusion.
Required
What can we conclude about the claim of the publisher.
From the question, we understand that the null hypothesis is rejected.
In statistics, a hypothesis is rejected, if the level of significance is less than the required or determined value.
In this case, the determined value 25% and the level of significance is 0.05
So, the conclusion on the claim is that there is enough evidence at the 0.05 significance level that the percentage is less than 25%.

[tex]t \ne 5[/tex]
[tex]x \le -3[/tex]
[tex]y \ne 1[/tex]
Step-by-step explanation:
Required
Translate to mathematical statements
a) r is less than or equal to ten.
less than or equal means [tex]\le[/tex]
So, the expression is:
[tex]r \le 10[/tex]
b) s is more than negative one
More than means >
So, the expression is:
[tex]s > -1[/tex]
c) t isn't the same as negative five.
isn't the same means not equal to ([tex]\neq[/tex])
So, the expression is:
[tex]t \ne 5[/tex]
d) x is at most negative three.
At most means [tex]\le[/tex]
So, the expression is:
[tex]x \le -3[/tex]
e) y is never one.
is never means not equal to ([tex]\neq[/tex])
So, the expression is:
[tex]y \ne 1[/tex]
Bags of sugar come in 3 sizes.
Small bag: A 175 g bag costs 55p.
Medium bag: A 525 g bag costs £1.76.
Large bag: A 1.15 kg bag costs £3.51.
Find the cost per gram for each bag of sugar.
Round your answers to 3dp.
Answer:
The cost per gram for each bag is:
Small bag: 0.00314 £
Medium bag: 0.00335 £
Large bag: 0.00305 £
Step-by-step explanation:
Small bag:
If 175 g cost 0.55 £, 1 g will be:
[tex] \frac{1g*0.55 \£}{175\: g} = 0.00314 \£[/tex]
Medium bag:
If 525 g cost £ 1.76, 1g will be:
[tex] \frac{1g*1.76 \£}{525\: g} = 0.00335 \£[/tex]
Large bag:
If 1150 g cost £ 3.51, 1g will be:
[tex] \frac{1g*3.51 \£}{1150\: g} = 0.00305 \£[/tex]

a moving box in the shape of a right rectangular prism has a base area of 5 5/8 ft² and a height of 3 1/5 ft what is the volume of the moving box
Answer:
18 ft^3
Step-by-step explanation:
The volume of a right rectangular prism is the area of the base multiplied by the height.
V = Ah
V = (5 5/8 ft^2) * (3 1/5 ft)
First, we convert the mixed numerals into fractions.
V = 45/8 ft^2 * 16/5 ft
Now we multiply the fractions.
V = (45 * 16)/(8 * 5) ft^3
Factor 45 into 5 * 9. Factor 16 into 2 * 8.
V = (5 * 9 * 2 * 8)/(8 * 5) ft^3
We can divide the numerator and denominator by 5 and by 8 before doing the multiplications.
V = (9 * 2)/1 ft^3
V = 18 ft^3

Because it is extremely hard to find the area of this figure all together, it would be in our best interest to split this figure up into three different pieces: the two horizontal rectangles, and the verticle rectangle. We can find the area of all three and add them up. Be aware that there are two different ways that you can break this figure up, As shown in the attachments. I will be using the first image (the one with the tall horizontal rectangles, NOT the almost-squares).
So, we see that we have enough information to solve for the area of the left-most rectangle. Area = lw. 10 x 4 = 40, so the area is 40. Next, we have to notice, that the horizontal rectangles are also the same, so both of the areas of the two horizontal rectangles are 40.
Now, we can find the middle rectangle. We know that the length of the entire thing is 18, but it is taken up by 8 (4+4) of the horizontal triangles, so 18-8=10, so the length Is 10. We also know that the height of the horizontal rectangles is 10, so 10-3=7. Our dimensions for the rectangle are 10x7 or 70 square units. If we add them all together, 40+40+70=150.
The area is 150 square units

can someone please help me with this math problem
Answer:
x= -1.1
Step-by-step explanation:
first combine like terms
3x+7x=10x
10x-8=-19
+8 on both sides
10x= -11
divide by 10
x= -1.1
check the answer
10(-1.1)-8= -19
-11-8= -19 its true

hope it's going to work ☺If a restaurant purchases organic food there is a 66% chance it will go bankrupt. If a restaurant does not purchase organic food there is a 64% chance it will go bankrupt. Only 12% of businesses purchase organic food. When a restaurant goes bankrupt what is the probability it purchased organic food
Answer:
0.1233 = 12.33% probability it purchased organic food
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Goes bankrupt
Event B: Purchase organic food.
Probability it goes bankrupt:
66% of 12%(purchases organic food)
64% of 88%(dont purchase organic food).
So
[tex]P(A) = 0.66*0.12 + 0.64*0.88 = 0.6424[/tex]
Intersection of A and B:
Bankrupt when purchases organic food. So
66% of 12%
[tex]P(A \cap B) = 0.66*0.12 = 0.0792[/tex]
When a restaurant goes bankrupt what is the probability it purchased organic food
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0792}{0.6424} = 0.1233[/tex]
0.1233 = 12.33% probability it purchased organic food

Noah bought 3 cans of paint and 1/2 of a pint of special paint additive formulated to reduce mildew. Before painting his house, he divided the additive equally among the 3 cans of paint. How much additive did he put in each can?
Step-by-step explanation:
Amount of additive in each can
= Total amount of additive / Number of cans
= (1/2 of a pint) / (3)
= 1/6 of a pint.
Noah put 1/6 of a pint of additive in each can.
A sound wave travels at 330m/s and has a wavelength of 2 m. calculate its frequency and period.
Answer:
frequency= 165Hz
period= [tex]\frac{1}{165}[/tex]
Step-by-step explanation:
1. To calculate the frequency using the formula:
f = v/λ
where,
f=frequency (what the question asked)
v=speed of wave (given in the question=330m/s)
λ=wavelength (given in the question=2m)
SO,
[tex]f=\frac{330}{2}[/tex]
= 165Hz
2. To calculate the period use the formula:
since [tex]f=\frac{1}{T}[/tex]
therefore, [tex]T=\frac{1}{f}[/tex]
where,
f= frequency (what we solved above=165Hz)
T= period (what the question asked)
SO,
[tex]T=\frac{1}{165}[/tex]
7/3 into a mix number
Answer: 2 1/3
Step-by-step explanation:
Answer and Step-by-step explanation:
To turn [tex]\frac{7}{3}[/tex] into a mixed number, we see how many times 3 goes into 7.
3 goes into 7 two times, so we put a two on the outside.
[tex]2\frac{1}{3}[/tex]
^ This is your answer, cause when you do 3 times 2, plus the numerator (1), you get 7.
