Step-by-step explanation:
-7Q + 6 + 5Q = 15 - 7
Q=-1
3 (P+5) + P = 3(2+P)
P=-3
2(A+4) + 6A = 2(2 + 3A)
A=-2
Answer:
There is not sufficient evidence to conclude that there exists significant difference in the birth weights of a mother's first child and second child at 10% level of significance.
Step-by-step explanation:
When our p-value exceeds level of significance then we fail to reject our null hypothesis. In this scenario we are investigating if there exists significant difference in the birth weights of a mother's first child and second child and our null hypothesis is there exists no significant difference in the birth weights of a mother's first child and second child i.e.μd=0.
As we are given that p-value is greater than 10% level of significant so, we cannot reject our null hypothesis. Thus, the conclusion statement can be written as "There is not sufficient evidence to conclude that there exists significant difference in the birth weights of a mother's first child and second child at 10% level of significance."
Yes they will all be trapezoid
You need to split the shape up into separate pieces so you can find their areas easily. I have shown this and the working out in the picture.
To find the measurements of the sides of the triangles, I just did 7-6=1 and 14-8=6 to find the missing lengths. So, your answer is 90 units^2
Answer:
(a) $2000
(b) $94.9
Step-by-step explanation:
The expected $ value of signing 100 deals with probability of 0.1 each is
E(X) = 100*0.1 + 100*0.1 + 100*0.1 + ... + 100*0.1 = 100(100*0.1) = $1000
Along with the fixed amount of $1000, the total next month salary is $2000
As for the standard deviation we can apply the following formula
