Before you can construct a ratio, both numbers must have
either the same units, or else NO units.
1 yard = 3 feet
12 yards = 36 feet
So the ratio is (99 feet) / (36 feet) = 11 / 4 .
Answer:
Step-by-step explanation:
Given that:
Mean μ= 100
standard deviation σ = 2.6
sample size n = 9
sample mean X = 100.6
The null hypothesis and the alternative hypothesis can be computed as follows:
The numerical value for the test statistics is :
z = 0.6923
At ∝ = 0.05
The critical value for the z score = 0.2443
From the z table, area under the curve, the corresponding value which is less than the significant level of 0.05 is 1.64
P- value = 0.244
c> If the true population mean is 101.3 ;
Then:
z = 0.808
From the normal z tables
P value = 0.2096
There are many ways to solve number 5 as it is just an reduce/enlargement of equidistant fractions
The first method that came up to my mind is just dividing denominators.
For A) you can do 72 divided by 18 which would give you 4. Then you can divide the given numerator with the answer you got from dividing the denominators. This would be 8 divided by 4 which would give you two. This means that 2/18 is equal to 8/72. You can check by simplifying the fraction. Both 2/18 and 8/72 equal 9 when simplified, therefore correct.
You can use this method for b, either use a calculator because of the decimals or just remove the decimals and replace them later. Make sure when you use this method, you are always dividing the bigger number. So in B you would do 40.3 divided by 12.4
Answer:
200
the ratio is 1:2 i thought about how i could get a solution then i realized i could split the 600 in too three parts to match the ratios different aspects and walla i got 200
Answer:
look down
Step-by-step explanation:
So basically its just asking you the change when you go to the next x-value.
In this question it looks like it is 4.
Hope this helps!
