2. H0: p = 0.53 Ha: p ≠ 0.53
Calculate the test statistic, rounded to 3 decimal places.
Answer:
-4.317
Step-by-step explanation:
The z test statistic for testing of 1-proportion can be computed as
We know that
phat=x/n.
We know that x=40 and n=120.
Thus,
phat=40/120=0.3333
p=hypothesized proportion=0.53
q=1-p=1-0.53=0.47
So, required z-statistic is
z=-4.317.
Thus, the required test statistic value for given hypothesis is z=-4.317.
1. Y= -4x + 3
2. Y= 4x + 3
3. Y= -(1/4) x +3
4. Y=- (1/4)x + 3
Answer:
It's might be 2 but I'm not for sure
Answer:
R" has coordinates (-4,6)
Explanation:
The pre-image is the original, while the image is the altered form. The image is notated by a '. When you alter the image ('), you get ".
T is dilated (multiplied) by 5, so it goes from T = (1,-2) to T' = (5, -10)
R = (-2, 3) → (multiply by 5) → R' = (-10, 15) → (multiply by 2/5 or 0.4) → R" = (-4, 6)
Answer: 105.9 lbs and 309.3 lbs
Step-by-step explanation:
By Chebyshev's Theorem, the proportion of patients with weights within 4.5 standard deviations of the mean is at least 95%. Therefore k=4.5.
The weight that is 4.5 standard deviations less than the mean is 207.6−4.5(22.6)=105.9 pounds.
The weight that is 4.5 standard deviations greater than the mean is 207.6+4.5(22.6)=309.3 pounds.
So at least 95% of the patients have weights between 105.9 and 309.3 pounds.
3x − y = 8
4x − 5y = 2
13x − 8y = 4
4x − 5y = 2
10x + 3y = 15
4x − 5y = 2
13x − 8y = 26
4x − 5y = 2
7x + 6y = 10
Answer:
4x − 5y = 2
13x − 8y = 26
Step-by-step explanation:
The equivalent system must have the same solution as the given system of equations:
4x − 5y = 2
3x − y = 8
Here we have that:
y = 3x - 8
4x - 5y = 2
4x - 5(3x - 8) = 2
4x - 15x + 40 = 2
-11x = -38
Now, we have to verify which of these systems have this answer:
4x − 5y = 2
13x − 8y = 4
13x - 8y = 4
4x − 5y = 2
10x + 3y = 15
10x + 3y = 15
4x − 5y = 2
13x − 8y = 26
4x - 5y = 2
13x - 8y = 26
This is the correct answer
So this is the correct answer
4x − 5y = 2
7x + 6y = 10
Answer:
The answer is
(4x - 5y = 2) and (13x - 8y =26)
