A job placement agency advertised at last year its clients, on average, had a starting salary of 39,000. Assuming the average refers to the mean, which of the following claims must be true based on this information? Last year the number of their clients who had a starting salary of 39,000 or above was equal to the number of their clients who had a starting salary of 39,000 or below. Last year all their clients had a starting salary of more than 37,000. Last year some of their clients had a starting salary of exactly 39,000. Two years ago at least one of their clients had a starting salary of at least 39,000. Or none of the above statements are true

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

1; 35 is the ratio

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
