G An article in Concrete Research "Near Surface Characteristics of Concrete: Intrinsic Permeability, (1989, Vol. 41) presented data on compressive strength x and intrinsic permeability y of various concrete mixes and cures. Summary quantities are n = 14, Xn i=1 yi = 572, Xn i=1 y 2 i = 23530, Xn i=1 xi = 43, Xn i=1 x 2 i = 157.42, Xn i=1 xiyi = 1697.80 Assume that the two variables are related according to the simple linear regression model. (a) (20pts) Calculate the least squares estimates of the slope and intercept.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

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

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
