If the null hypothesis is statistically significant at level α = 0.05, it means that the probability of obtaining the observed result by chance is less than 5%. Therefore, the correct answer is A. Therefore, if we increase the significance level to α = 0.10, which means allowing for a higher probability of obtaining the observed result by chance, the test would still be significant.
When conducting a statistical hypothesis test, a significance level is set to determine whether to reject the null hypothesis or not. A common significance level is α = 0.05, which means that if the probability of obtaining the observed result by chance is less than 5%, we reject the null hypothesis. If the null hypothesis is statistically significant at α = 0.05, it means that the observed result is unlikely to have occurred by chance, and we have evidence to support the alternative hypothesis.
If we increase the significance level to α = 0.10, we are allowing for a higher probability of obtaining the observed result by chance. Therefore, the test would still be significant if it was statistically significant at α = 0.05, but may not be significant at α = 0.01, which requires a lower probability of obtaining the observed result by chance. It's important to note that the standard normal distribution is not uniform, but rather bell-shaped, symmetric about the mean, and unimodal. Therefore, option B, which states that the standard normal distribution is uniform, is not true, while options C and D are also not true.

what is the measurement of angle x
the angle on the right measures 54 degrees and the left measures 38 degrees
Answer:
16
Step-by-step explanation:
180 is a straight line.
x is among that line so you must subtract the angles you know from 180.

Write an equation of a line perpendicular to x = -7 and passes through the
point (4,9).
Answer:
y = 9
Step-by-step explanation:
The line x = -7 is a vertical line, so the perpendicular line will be horizontal.
Horizontal lines have a slope of 0.
Using this slope and the point given, plug them into y = mx + b to solve for b and create the equation
y = mx + b
9 = 0(4) + b
9 = b
Plug this and the slope into the equation:
y = mx + b
y = 0x + b
y = 9
So, y = 9 is the equation

Why does the sin 0 = cos (90 - 0)?
Answer:
It is a nonexistent circumstance where one point of a correct triangle gets zero. Attempt to think. At the point when the point becomes zero, at that point the base gets 0, and the opposite and the hypotenuse turns into a similar line. Since in cos 90, base is 0, in this manner consequently cos 90 is zero.

Draw the image of the following segment after a dilation centered at the origin with a scale factor of 2/3
Answer:
When we have a point (a, b) and we have a dilation of scale factor K centered at the origin, the new coordinates of this point will be:
(K*a, K*b)
In this case, we can find the original coordinates of the endpoints of the original segment.
Then apply the dilation to these points, and then draw a new segment whose endpoints are the dilated points.
The endpoints of the original segment are (i can not see the image very well, so i may be wrong when noticing the points).
The first endpoint is (6, 9) and (12, 12)
Now we apply a dilation with a scale factor K = 2/3.
then we get the points:
((2/3)*6, (2/3)*9) = (4, 6)
and the other point is:
((2/3)*12, (2/3)*12) = (8, 8)
Now we need to draw a segment whose endpoints are (4, 6) and (8, 8)
The segment can be seen in the graph below.

Christie has $3.80 in quarters and dimes. She has three more dimes than quarters. How many of each coin does she have?
Answer:
Quarters = 10
Dimes = 13
Step-by-step explanation:
Given that :
Quarters = $0.25
Dimes = $0.10
Total value =. $3.80
Let :
Quarters = a
Dimes = a + 3 (3 more dimes Than quarters)
0.25a + 0.10(a + 3) = 3.80
0.25a + 0.10a + 0.3 = 3.80
0.35a = 3.80 - 0.3
0.35a = 3.5
a = 3.5 / 0.35
a = 10
Quarters = a = 10
Dimes = a + 3 = 10 + 3 = 13
