Answer: A. Alice could have 6 and Claire have 18 and if Alice has 12 apples and Claire has 36 apples and then Alice has 18 apples and Claire has 54 apples.
B= 1:3 For every 1 apple Alice has Claire has 3 apples

Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ ≥ 50000
For the alternative hypothesis,
µ < 50000
Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is
z = (x - µ)/(σ/√n)
Where
x = lifetime of the tyres
µ = mean lifetime
σ = standard deviation
n = number of samples
From the information given,
µ = 50000 miles
x = 45800 miles
σ = 8000
n = 29
z = (50000 - 45800)/(8000/√29) = - 2.83
Looking at the normal distribution table, the probability corresponding to the z score is 0.9977
Since alpha, 0.05 < than the p value, 0.9977, then we would accept the null hypothesis. Therefore, At a 5% level of significance, the data is not highly consistent with the claim.
Answer:
If 9 liters 400 millitres of water is further added, there will be 20 liters of water in the tub.
Step-by-step explanation:
Given that a tub contains 10 liters 600 millitres of water, to determine, if 9 liters 400 millitres of water is further added to this, what will be total water in the tub, the following calculation must be performed:
1 liter = 1000 milliliters
0.6 liters = 600 milliliters
10.6 + 9.4 = X
20 = X
Therefore, if 9 liters 400 millitres of water is further added, there will be 20 liters of water in the tub.
Answer:
117.53 feet^2
Step-by-step explanation:
So to start off we need to find the area of the pentagon.
The formula for the area of a pentagon is weird so I’m not going to write it but you can search it up.
So the area would be 27.53 inches^2.
Now for the triangles.
There is 5 triangles in total with a base of 4 and a height of 9.
So the area of one is base*height divided by two.
So it would be 18.
Now we can just multiply 18 by 5 which is 90 feet^2.
So when we add up 90 and 27.53 we get 117.53 feet^2.
