Jacob traveled 92 miles.

<u>Solution:</u>

Given:

Speed of Jacob = 23 miles per hour

Time traveled = 4 hours

To find: The distance traveled

Distance travelled can be calculated by multiplying the speed and the time traken to cover the distance. Mathematically the formula is

\bold{D=s\times t}

where D is distance, s is speed and t is time.

Here s is 23 and t is 4, On substituting the value we get,

\bold{Distance=23\times4=92}

The distance = 92 miles

ser-zykov [4K]

Answer:

6 Slices Of Cheese Remaining

Step-by-step explanation:

50% of the cheese is 16 slices, so add on 50% + 25% and you get 24 slices...

if you do 32-24 you have 8 slices remaining and if you eat 25% of the 8 slices you have 6 slices left.

katrin [286]

Answer:

Step-by-step explanation:

Polynomials in one variable are algebraic expressions that consist of terms in the form a x n a x n where n is a non-negative (i.e. positive or zero) integer and a is a real number and is called the coefficient of the term. The degree of a polynomial in one variable is the largest exponent in the polynomial

Two college roommates have each committed to donating to charity each week for the next year. The roommates’ weekly incomes are
schepotkina [342]

Answer:

C. 5 weeks.

Step-by-step explanation:

In this question we have a random variable that is equal to the sum of two normal-distributed random variables.

If we have two random variables X and Y, both normally distributed, the sum will have this properties:

S=X+Y\\\\\ \mu_S=\mu_X+\mu_Y=30+60=90\\\\\sigma_S=\sqrt{\sigma_X^2+\sigma_Y^2}=\sqrt{10^2+20^2}=\sqrt{100+400}=\sqrt{500}=22.36

To calculate the expected weeks that the donation exceeds $120, first we can calculate the probability of S>120:

z=\frac{S-\mu_S}{\sigma_S} =\frac{120-90}{22.36}=\frac{30}{22.36}=1.34\\\\P(S>120)=P(z>1.34)=0.09012

The expected weeks can be calculated as the product of the number of weeks in the year (52) and this probability:

E=\#weeks*P(S>120)=52*0.09012=4.68

The nearest answer is C. 5 weeks.
