It would be negative 22 because if u dived 20 and 5 you will get negative 22 because I’m very smart if u think so give me a 5 out of 5
Answer:
108 ft long
Step-by-step explanation:
they both form similar triangles like shape
therefore



Answer:
Option B
Step-by-step explanation:
Let the point O is the origin.
Then the coordinates of the vertices A,B and C will be,
A → (-12, -8)
B → (-8, 0)
C → (-6, -4)
Rule for the dilation of a point (x, y) by scale factor 'k' about the origin is,
(x, y) → (kx, ky)
By this rule, coordinates of the vertices of the image triangle will be,
If k =
,
A(-12, -8) → A'(-6, -4)
B(-8, 0) → B'(-4, 0)
C(-6, -4) → C'(-3, -2)
From the given options,
Option B is the answer.
Answer:
d. t-test for means
Step-by-step explanation:
Options are <em>"a. z-test for proportions, b. z-test for means, c. none of the other three answers, d. t-test for means"</em>

Sample size = n = 120
Sample mean = x = 0.8
Sample standard deviation = s = 2
Claim: A particular diet helps loss weight.
<u>Hypothesis test</u>
The null and alternative hypothesis is
H0 : μ = 0
Ha : μ < 0
Now, when population standard deviation is unknown we use t-test otherwise use z-test. So, the kind of hypothesis testing that we use is t-test for means.
