Answer: I’m not really sure what the correct answer is if you could help that would be great so let me know
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Remarks
- The given angle is an exterior angle.
- It's value is 46 degrees.
- An exterior angle is the sum of the two remote angles. (A remote angle is one that is not supplementary to the given exterior angle.
Solution
- 46 = <u + <t
- <t = 29
- 46 = <u + 29 Subtract 29 from both sides.
- 46 - 29 = <u
- <u = 17 degrees
Answer:
1.) mean
2.) H0 : μ = 64
3.) 0.0028
4) Yes
Step-by-step explanation:
Null hypothesis ; H0 : μ = 64
Alternative hypothesis ; H1 : μ < 64
From the data Given :
70; 45; 55; 60; 65; 55; 55; 60; 50; 55
Using calculator :
Xbar = 57
Sample size, n = 10
Standard deviation, s = 7.14
Test statistic :
(xbar - μ) ÷ s/sqrt(n)
(57 - 64) ÷ 8 / sqrt(10)
Test statistic = - 2.77
Pvalue = (Z < - 2.77) = 0.0028 ( Z probability calculator)
α = 10% = 0.1
Reject H0 ; if P < α
Here,
P < α ; Hence, we reject the null
-6 5 -3 is the corrdante did those sir
I'm not sure if this is right but you can set up an equation and solve to find Maggie's age:
Maggie's brother's age = b
Maggie's age = m
b = 12 - 3m
44 = 12-3m
12-3m = 44
-12 -12
-3m = 32
÷ 3 ÷3
m = 10.67
So this would be Maggie's age
I hope this helped :)
