Answer:
112°
Step-by-step explanation:
Given that the diagonals of trapezoid RSTU are congruent, it is an Isosceles Trapezoid.
One of the properties of an Isosceles Trapezoid is that the base angles are equal.
Therefore if the measure of angle S=112°, the measure of Angle U will also be 112°.
The fraction of squares shaded to total squares is 70/100 or 7/10
With a percent, 70% of all of the squares are shaded
With a decimal, there are 0.7 shaded blocks for every total block, so it is 0.7
Hope this helps!
This is a typo and vaguely phrased. However, the closest to a direct solution is to think of it as follows: 35% of the cars are speeding. Out of these, 52% of the cars are also speeding. Hence, the result of cars that are both speeding and speed cars is 0.52*0.35=0.182
Answer:
h = 13
Step-by-step explanation:
Given the area of a triangle as 84.5 .
The correct value to complete the formula to calculate for the height h is 13 .
Area of a triangle = 1/2 b x h
b = base
h = height
Using the above formula
84.5 = 1/2 x 13 x h
84.5 = 13/2 x h
84.5 = 6.5 x h
84.5 = 6.5h
Divide both sides by 6.5 to get h
84.5/6.5 = 6.5h /6.5
13 = h
h = 13
Answer:
The critical t values are -1.746 and 1.746.
Step-by-step explanation:
Given information:
The weight of a USB flash drive is 30 grams and is normally distributed.
Population mean = 30
Sample size = 17
Sample mean= 31.9
Standard deviation = 1.8
Significance level, α=0.10
Null hypothesis: 
Alternative hypothesis: 
It is a two tailed test.
The t-critical values for a two-tailed test, for a significance level of α=0.1 are -1.746 and 1.746.
Therefore the critical t values are -1.746 and 1.746.
