Answer:
p-value: 0.453
Step-by-step explanation:
Hello!
You have two study variables
X~N(μₓ;σₓ²)
nₓ= 4
X[bar]ₓ= 149.50
Sₓ= 10.66
Y~N(μ;σ²)
= 6
X[bar]= 158.17
S= 19.87
The hypothesis is:
H₀: μₓ = μ
H₁: μₓ ≠ μ
The statistic to use is a pooled t for independent samples with unknown but equal population variances
t= [(X[bar]ₓ - X[bar]) - (μₓ - μ)]/[Sa/√(1/nₓ + 1/)]
The value of the statistic is:
t= -0.789
For this statistic value the corresponding p-value is:
P(t ≤ -0.789) + (1 - P(t ≤ 0.789) = 0.453
I hope it helps!
Answer:
8√30
Step-by-step explanation:
The length of the third side is 32 - 8 - 11 = 13. s (which is half of the perimeter) is 32 / 2 = 16 so the answer is:
√s(s-a)(s-b)(s-c) = √16 * (16 - 8) * (16 - 11) * (16 - 13) = √16 * 8 * 5 * 3 = √1920 = 8√30
Answer:
Step-by-step explanation:
Mike's total pay is the result of dividing a fixed amount of time between two jobs. The total hours and the total pay give us two relations that let us solve for the time at each job.
Let x represent the number of hours Mike works at Job B. Then 56-x is the number of hours he works at Job A. His total pay for both jobs is ...
8x +7(56 -x) = 410
x +392 = 410 . . . . . . simplify
x = 18 . . . . . . . . . subtract 392
56 -x = 38 . . . find Job A hours
Mike works 38 hours at Job A, and 18 hours at Job B.

Answer:
x = - 7, x = 6
Step-by-step explanation:
to find the x- intercepts set f(x) = 0, that is
x² + x - 42 = 0
To factor, consider the factors of - 42 which sum to + 1
These are + 7 and - 6
(x + 7)(x - 6) = 0
equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x - 6 = 0 ⇒ x = 6
