Answer:
False, A equation DOES have to have a equal sign.
Step-by-step explanation:
Answer:
It is an unusual result contradicting the national survey.
Step-by-step explanation:
National survey showed 44% of college students who drink.
The professor's survey showed that 96/244 = 39% drink.
The professor's survey deviated from the national survey is 5% (44% - 39%) representing about 0.25% (5% squared) variance.
Standard deviation is the spread of a set of numbers from their mean. In other words, it measures how far an observed value is from the mean. It can be calculated by getting the square root of the variance.
Write and solve an equation of ratios:
x 9
---- = ----
16 x
Cross mult., we get x^2 = (16)(9)
Taking the sqrt of both sides, we get x = plus or minus (4)(3), or
x= plus or minus 12
Since x is measure of distance here, omit the -12 result. x = +12 units
Answer:
178
Step-by-step explanation:
The area of the rectangle is 6x25=150.
The area of the two semicircles on the sides is equal to the area of one circle with a radius of 3, so the area is
which is approximately 28.27.
150+28.27=178.27
C would be your answer. The original equation is 4(x)^2 - 16. When you shift to the right, you subtract x by that amount. Then you subtract -16 by 3 to go down
