Answer:

Percentage of Pennies is 40

Step-by-step explanation:

Total coins are 600

Pennies are 240

= 0.4 × 100%

= 40%

Answer:

(f o g)(4)=27

Step-by-step explanation:

(f o g)(4)=2x+5

f(g(4))=2x+5

f(4²-2(4)+3)=2x+5

f(16-8+3)=2x+5

f(8+3)=2x+5

f(11)=2x+5

f(11)=2(11)+5

f(11)=22+5

f(11)=27

Therefore, (f o g)(4)=27

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

What is the arc measure of abc in degrees

Virty [35]

Given:

The measure of arc AB is (4y + 6)°

The measure of arc BC is (20y - 11)°

The measure of arc AC is (7y - 7)°

We need to determine the measure of arc ABC.

Value of y:

The value of y is given by

$m \widehat{AB}+m \widehat{BC}+ m \widehat{AC}=360$

Substituting the values, we get;

$4y+6+20y-11+7y-7=360$

Adding the like terms, we have;

$31y-12=360$

Adding both sides of the equation by 12, we have;

$31y=372$

$y=12$

Thus, the value of y is 12.

Measure of arc ABC:

The measure of arc ABC can be determined by adding the measure of arc AB and arc BC.

Thus, we have;

$m \widehat{ABC}=m \widehat{AB}+ m \widehat{BC}$

$m \widehat{AB}+m \widehat {BC}=4y+6+20y-11$

$=24y-5$

Substituting y = 12, we get;

$m \widehat{AB}+m \widehat {BC}=24(12)-5$

$=288-5$

$m \widehat{AB}+m \widehat {BC}=283^{\circ}$

Thus, the measure of arc ABC is 283°
