Answer:
120 Kg : 72 Kg
Step-by-step explanation:
Sum the parts of the ratio, 5 + 3 = 8 parts
Divide the quantity by 8 to find the value of one part of the ratio.
192 Kg ÷ 8 = 24 Kg , thus
5 parts = 5 × 24 Kg = 120 Kg
3 parts = 3 × 24 Kg = 72 Kg
192 Kg = 120Kg : 72 Kg in the ratio 5 : 3
4n + 22 < 82 <=== ur inequality
Answer:
12/52 or 23%
Step-by-step explanation:
take the total of all the candy and divide it by the number of green so there are 12 green and 52 over all so it would be 12/52
Answer:
Now we can calculate the p value but first we need to calculate the degrees of freedom for the statistic. For the numerator we have and for the denominator we have and the F statistic have 15 degrees of freedom for the numerator and 15 for the denominator. And the P value is given by:
For this case the p value is highert than the significance level so we haev enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviations are not significantly different
Step-by-step explanation:
Information given
represent the sampe size 1
represent the sample 2
represent the sample deviation for 1
represent the sample variance for 2
represent the significance level provided
The statistic is given by:
Hypothesis to test
We want to test if the variations in terms of the variance are equal, so the system of hypothesis are:
H0:
H1:
The statistic is given by:
