Is A the point or coordinate in A(3,5)

Answer:

B

Step-by-step explanation:

Mathematically, we shall be using the z-score here

Z-score = (x-mean)/SD

From the question, mean = 80 and SD = 4

So we want to get the option in the question that has a z-score of 1 or below

Let’s look at 75

80-75 = 5 ( this is clearly above 1 standard deviation of 4)

For 77;

80 -77 = 3

This is less than the standard deviation of 4, meaning it is within 1 standard deviation of the mean

Option B) is correct.

Step-by-step explanation:

Given :

Mean [tex](\mu)[/tex]  = 80

Standard Deviation [tex](\sigma)[/tex]  = 4

Calculation :

We have to find the score that would be 1 deviation from the mean. Which means, the interval [tex](\mu-\sigma, \mu+\sigma)[/tex]

[tex]\mu-\sigma = 80-4=76[/tex]

[tex]\mu+\sigma =80+4=84[/tex]

The interval is (76,84)

Therefore, option B) is correct.

Answer:

5°F

Step-by-step explanation:

Given that the average is obtained from;

Average = sum of scores / number of scores

Average temperature = 19.8°F

Let the temperature of the fifth day be x

Hence;

19.8 = 32 + 30 + 22 + 10 + x/5

19.8 = 94 + x/5

x= (5×19.8) -94

x= 5°F

Answer:

x = 6.5

Step-by-step explanation:

5(x−2)+3x−4= 38

5 times x, 5 times -2 =

5x - 10 + 3x - 4 = 38

Combine like terms

5x + 3x = 8x

8x - 10 - 4 = 38

Add 10

8x -10 +10 -4 = 38 +10 =

8x -4 = 48

Add 4

8x -4 +4 = 48 +4

8x = 52

Divide by 8

8x/8 = 52/8 =

x = 6.5

Answer:

75.6

Step-by-step explanation:

75.64 rounded to the nearest 10th is 75.6.

The tenths place is 0.6, and since the next number is not larger than 5, the number is rounded to 75.6.

Answer:

75.6

Step-by-step explanation:

75.64

The 6 is in the tenths place.

Drop all digits to the right of the 6.

75.6

Since the leftmost digit you dropped is a 4, the 6 does not go up 1 to 7, so the answer is

75.6

Ryan earned $233.40 from the tips. Option D is correct

Ryan works at the car wash making $5.30 per hour plus tips.
Last week Ryan worked 32 hours and earned $403
How much in tips did Ryan make last week?

In mathematics, it deals with numbers of operations according to the statements.

Let the tip Ryan get be x,
Ryan earned $5.30 per hour.
Ryan earned $403 for 32 hours of the working,
Ryan worked 32 hours so,
Ryan earned = 32 * 5.30
                      = 196.4
Total tips that Ryan earned = total earning - Ryan earned
                                               = $403 - $196.4
                                               = $233.40

Thus, Ryan earned $233.40 from the tips. Option D is correct

Answer:

[tex]Frozen\ Soup = 7550mL[/tex]

Step-by-step explanation:

Given

[tex]Soup = 9,350mL[/tex]

[tex]Packed = 1.8L[/tex]

Required

Determine the frozen soup

This is calculated as thus:

[tex]Frozen\ Soup = 9,350mL - 1.8L[/tex]

Convert 1.8L to mL

[tex]Frozen\ Soup = 9,350mL - 1.8 * 1000mL[/tex]

[tex]Frozen\ Soup = 9,350mL - 1,800mL[/tex]

[tex]Frozen\ Soup = 7550mL[/tex]

Answer:

The third one I think

Step-by-step explanation:

[tex]f(x) = {x}^{2} + 7 [/tex]

[tex]y = {x}^{2} + 7 [/tex]

Subtract the sides of the equation minus 7

[tex]y - 7 = {x}^{2} [/tex]

Take the square root of both sides of the equation

[tex]x = \sqrt{y - 7} [/tex]

So ;

[tex] {f}^{ - 1}(x) = \sqrt{x - 7} [/tex]

Answer:

y = 2 x - 6

the second answer is

y + 6 = 2 (x - 0)

Step-by-step explanation:

The equations that would guarantee that lines p and q are parallel are;

x = z

x + y = 180°

The image showing the lines p and q as well as the angles x, y and z can be found in the link at the end of this answer.

From the image given;

We see that a transverse line cuts across the two parallel lines p and q. Thus;

We can see that x and z are corresponding angles and as such, we can say that; x = z.

Secondly, we can see that y and z are supplementary angles because they form a straight line and sum of angles that form a straight is 180°.

Thus; y + z = 180°

Since x = z, then by substitution property of equality, we can say that;

x + y = 180°

Step-by-step explanation:

Let's solve your inequality step-by-step.

122<−2(8x+3)

Step 1: Simplify both sides of the inequality.

122<−16x−6

Step 2: Flip the equation.

−16x−6>122

Step 3: Add 6 to both sides.

−16x−6+6>122+6

−16x>128

Step 4: Divide both sides by -16.

−16x /−16 > 128 /−16

Answer:

12 hours

Step-by-step explanation:

So we know that Jim makes $5 an hour and was given a one time bonus of $50. Using the information given, we can make the expression:

5h + 50

to represent how much Jim makes in h hours.

Now we also know that Sarah makes $8 an hour and was given a one time bonus of $14. Using this information, we can make the expression:

8h + 14

to represent how much Sarah makes in h hours.

Now to find how many hours it will take for their paychecks to be the same, we have to set the two expressions equal to each other and solve for h:

8h + 14 = 5h + 50

Now solve for h. Subtract 5h from both sides.

3h + 14 = 50

Subtract 14 from both sides.

3h = 36

Divide both sides by 3.

h = 12

So it will take 12 hours for their paychecks to be the same.
