Add all the numbers together:
100+50= 150
150+25= 175
175+12.5= 187.5
187.5 is the sum.
I hope this helps!
Answer:
(3, 3)
Step-by-step explanation:
Apparently, you want to find the value of y that corresponds to the value x=3. Put x=3 into the equation and do the arithmetic.
y = 4(3) -9 = 3
The missing value is 3, and the ordered pair is ...
(3, 3)
Answer: (1.4964, 1.5126)
Step-by-step explanation:
We know that the confidence interval for population mean is given by :-
, where = population standard deviation.
n= sample size
= Sample mean
As per given , we have
σ = 0.01 inches
n= 10
Also, the critical value for 99% confidence interval = [From x-value table.]
[Significance level =1-0.99=0.01 and is 2.576.]
Then, the 99% two-sided confidence interval on the mean hole diameter will be :-
Hence, the required confidence interval = (1.4964, 1.5126)
Answer:
6%
To find 6 percent of a number, multiply the number by 0.06. In this instance, 3.5 x 0.06 = 0.21, or twenty-one hundredths.
Step-by-step explanation:
Answer:
x = 70°
Step-by-step explanation:
Clockwise from top, call the three tangent points A, B, and C. Central angle AXC is the supplement of the marked external angle, so is 140°. Arc AB is bisected by the upper ray of angle x; and arc BC is bisected by the lower ray of angle x. That is to say x is half the measure of arc AC, so is 70°.
__
Attached is the output of a geometry program. The angle at lower left is 40° as in the given figure. The central angle α (70°) remains the same as tangent point C is moved around, which is to say that the measure of the angle α does not depend on the dimensions of the triangle containing α. It just depends on the fact that the triangle is tangent to the circle.
