JT has two jobs. He mows yards and washes cars in his neighborhood. Let X represent the amount of weekly earnings for mowing yards, and let Y represelit the amount of weekly earnings for washing cars. The mean of X is
$60, and the mean of Y is $35. Which answer choice correctly calculates and interprets the mean of the sum, S = X
+ Y?
Os = 47.5; next week, JT will earn $47.5.
O
Ws = 47.5; JT can expect to earn $47.5, on average, in a typical week.
O
Hs = 95; next week, JT will earn $95.
0
Hs = 95; JT can expect to earn $95, on average, in a typical week.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
