Solution :
The null and alternative hypothesis is given by


Assume that the level of significance, α = 0.05
The t-test statistics is, t = 1.484
Degree of freedom :
df = n - 1
= 14 - 1
= 13
The P-value is given by
P-value = 2P (T>|t|)
= 2P(T>|1.484|)
= 2P(T>1.484)
= 2(=T.DIST.RT(1.484,13))
= 0.05
Multiplication would be first
Let c represent the original amount that this guy had saved up.
He spent 25% of this amount, or 0.25c, on the printer.
To progress further, we have to know how much the printer cost.
Supposing that the printer cost $100 (which we do not know as a fact), this would be equal to 0.25c.
Thus, his savings originally amounted to c = $100/0.25 = $400.
Answer:
y=-6
Step-by-step explanation:
Method 1:
Both the y coordinates of the points are the same and the x coordinates are distinct.
Therefore the straight line passing through the point is parallel to X-axis.
The common y coordinate is -6, therefore the line equation is y=-6.
Method 2:
We will solve it using general line equation
(y-y1)=(
)(x-x1)
where (x1,y1) and (x2,y2) are the 2 points.
- (y+6)=(
)(x+2)
Answer:
arc AM = 114°
Step-by-step explanation:
the measure of a tangent- chord angle is half the measure of its intercepted arc, that is
∠ MAC =
(AM )
57° =
AM ( multiply both sides by 2 to clear the fraction )
114° = AM
