Determine the area under the standard normal curve that lies to the right of the z-score of 1.44. (Use a four-digit decimal. No rounding necessary.)

Answers

Answer:

The area is 0.0749

Step-by-step explanation:

The area under the standard normal curve represents probability and has a total value of 1

Now, to the right of the z-score 1.44, the area we are considering is the probability below;

P( z > 1.44)

To get this value, we need to use the standard normal distribution table

Checking this, the probability is

P( z > 1.44) = ) = 0.074934 which is 0.0749 for a four decimal digit

Elijah is trying to make extra money on his summer vacation from school. He works two different jobs, earning $8 per hour babysitting and $10 per hour lifeguarding. How much money would Elijah earn in a week in which he worked 3 hours babysitting and 7 hours lifeguarding?

Answers

Answer:

$94

Step-by-step explanation:

8x + 10x =  y

8 (3) + 10 (7) = y

24 + 70 = y

94 = y

Answer with step-by-step explanation:

If he were to work a full week, then 3 hours babysitting × 7 days a week × $8 for work = $168 for babysitting. 7 hours lifeguarding × 7 days a week × $10 for work = $490 for lifeguarding.

The total amount of money that Elijah would earn is $168 + $490 = $658

Suppose you have a total of $2.25 in dimes and
nickels. You have twice as many dimes, as nickels.
Which system of equations could be used to
determine how many of each coin you have?

Answers

Answer:

n = number of nickels

2n = number of dimes

n($0.05) + 2n($0.10) = $2.25

0.05n + 0.2n = 2.25

0.25n = 2.25

n = 2.25/0.25 = 9

2n = 2(9) = 18

You has 9 nickels and 18 dimes

Solve this equation
100x + 300 = 200

Answers

Answer:

-1

Step-by-step explanation:

100x=200-300

100x=-100

100x/100=-100/100

x=-1

After solving this equation we get, 100x + 300 = 200 x = -1.

To solve this equation

100x + 300 = 200,

Subtract 300 on both side,

100x + 300 - 300 = 200 - 300

100x = -100

Divide 100 on both side,

x = -1

Therefore, After solving this equation 100x + 300 = 200 we get x = -1.

15(15b−7)=3b−9 plz help meee

Answers

Answer:

B=16over37

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

15(15b−7)=3b−9

(15)(15b)+(15)(−7)=3b+−9(Distribute)

225b+−105=3b+−9

225b−105=3b−9

Step 2: Subtract 3b from both sides.

225b−105−3b=3b−9−3b

222b−105=−9

Step 3: Add 105 to both sides.

222b−105+105=−9+105
