Greg made pudding every weekend. The more times he made pudding, the more practice he gained. The time he took to make the same

VashaNatasha [74]

After Greg makes the pudding 1 time, it takes him $f(1)=2(0.8) ^{1}=1.6$ hours to make it.

After Greg makes the pudding 2 times, it takes him $f(2)=2(0.8) ^{2}=1.28$ hours to make it

After Greg makes the pudding 2 times, it takes him $f(3)=2(0.8) ^{3}=1.024$ hours to make it

so The function is $f(x)=2(0.8) ^{x}$

Answer: f of x equals 2 multiplied by 0.8 to the power of x

the strength of students in a school when increased by 8% becomes 2160. find the original strength of students in the school.

Leni [432]

Answer:

1987.2

Step-by-step explanation:

We can write a proportion to find the total amount in the choir using the information given. A proportion is two equivalent ratios set equal to each other. Since we know the strength of students increased by 8% to 2160 then the original was 92%.

$\frac{92}{100}=\frac{y}{2160}$

We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.

92(2160)=100(y)

198720=100y

y=1987.2

There are 1987.2 as the original strength of students.

A carnival game has the possibility of scoring 50 points, 75 points, or 150 points per turn. The probability of scoring 50 point

MariettaO [177]

Answer:

The game’s expected value of points earned for a turn is 71.

Step-by-step explanation:

Here we know that:

Points Frequency

50 55

75 32

150 13

Here points earned is a random variable.

We need to find its expected value,

Finding Expected value:

Expected value of a random variable is its mean value. So we will first find the mean value of points earned per turn from the table we are given.

Total number of turns = sum of frequencies

= 55 + 32 + 14 = 100

Total points earned = 50(55) + 75(32) + 150(13)

= 7100

Expected value of points earned for a turn = Mean value of points

= Total points/no. of turns

= 7100/100

= 71
