Answer:
y= -10/89
Step-by-step explanation:
89y=-10
89y/89 = -10/89
y= - 10/89
Add all the numbers up but pay attention you are counting 6.30 twice. then you divide by the numbers of days you have.(5)
<span>Your answer should be 5.47</span>
The first partner in the handshake can be any one of 15 people.
The second partner can be any one of 14 people.
So the total number of possible arrangements is (15 x 14) = <u>210</u> .
<em><u>BUT . . . .</u></em>
If Mr. Smith and Mr. Jones are shaking hands, it doesn't matter which one is the first partner and which one is the second partner ... It's the same handshake either way.
That number of ' <u>210</u> ' up above counted both ways separately. The real number of handshakes <em>between different people</em> is half of that 210/2 = <em>105 handshakes</em>.
All this question is asking you to do is multiply 65 and 7. The 7 comes from the amount of days in a week. The product of these numbers is 455.
Maria did 455 sit-ups in a week.
Answer:
No, because the largest standard deviation is more than twice the smallest standard deviation.
Step-by-step explanation:
Okay, so the standard deviation for each of the sample is given as;
NHES II study = 2.486, NHANES II study = 2.408 and NHANES study = 5.851.
In order to determine whether the standard deviations satisfy the guidelines for the use of ANOVA, one of the conditions for anova for sample standard deviations must be considered that is;
'' the value of the sample standard deviations should not be times two of the smallest standard deviation."
In which if we have; highest sample standard deviations / smallest standard deviation < 2, Then, population variance is equal.
