Identify the functions that have the given property.

The domain is all real numbers for . A sine function, B consine function, C both sine and cosine function

An x-intercept is (pi,0) for A sine function, B consine function, C both sine and cosine function

The minimum value is –1 for .A sine function, B consine function, C both sine and cosine function

An x-intercept is (pi/2, 0) for .A sine function, B consine function, C both sine and cosine function
#1 is c, #2 is A, #3 is C, #4 is B

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
