The score on a test are normally distributed with a Mean of 140 and a standard deviation of 28 find the score of that is one and a half standard deviation 140 standard deviation 28 score is one and a half standard deviation

Answers

Answer 1

The score that is one and a half standard deviation is 182.

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x\ is\ raw\ score, \mu\ is\ mean, \sigma\ is\ standard \ deviation[/tex]

Given that:

μ = 140, σ = 28. For a z score of 1.5(one and a half):

[tex]1.5=\frac{x-140}{28} \\\\x-140=42\\\\x = 182[/tex]

The score that is one and a half standard deviation is 182.

Find the 37th term.
Find the 37th term.

Answers

Answer:

The 37th term is 136.

Step-by-step explanation:

The sequence has a common difference therefore, it is an arithmetic sequence

The formula for arithmetic sequence is

[tex]an = a1 + (n - 1)d[/tex]

where,

an is the nth term,

a1 is the first term,

n is the term number and

d is the common difference

Find the 37th term.

an = a1 + ( n-1 ) d

Find the unit price for a 9 oz bottle of ketchup for 88cents. round answers to the nearest tenth of a cent. ________ cents per ounce

Answers

Answer:

0.1 cents per ounce

Step-by-step explanation:

You know that you paid 88 cents for the whole bottle of ketchup and the whole body contains 9oz of ketchup. Every one ounce is equal to 9.8 cents. You simply need to divide the total amount of the item by the weight (9 ounces) to get 0.09 or 0.1 when rounded.

Answer:

Step-by-step explanation:

This is an exterior angle theorem question.

To answer this question, you must know what the exterior angle theorem is:

An exterior angle of a triangle is equal to the sum of the two opposite interior angles. (not my definition)

So first, you need to add the two opposite interior angles.

3x+8+2x+9 is equal to 5x+17.

Then, you make an equation setting 5x+17 equal to the exterior angle.

5x+17 = 8x-16.

To solve this equation, first add 16 on both sides

→5x+33 = 8x

Then, subtract 5x on both sides

→ 33 = 3x

Finally, divide both sides by 3 to get x=11

Gemma and Leah are both jewelry makers, Gemma made 106 beaded necklaces. Leah
made 39 more necklaces than Gemma.
Each necklace they make has exactly 104 beads on it. How many beads did both
Jewelers use altogether while making their necklaces? How many necklaces did Gemma and Leah each make

Answers

Answer:

Gemma made $34 more than Leah.

Step-by-step explanation:

Gemma made number of beaded necklaces = 106

Leah made 39 more necklaces than Gemma.

Leah made number of beaded necklaces  = 106 + 39 = 145

a. There are 104 beads on each necklace.

The total number of beads used altogether

= (106 × 104) + (145 × 104)

= 11,024 + 15,080

= 26,104

b. Gemma sold her 106 necklaces for = $14

Total price of her necklaces = 106 × 14

                                              = $1,484

Leah sold her 145 necklaces for = $10

Total price of her necklaces = 145 × 10

                                              = $1,450

Difference in Gemma and Leah's amount = 1484 - 1450 = $34.00

Therefore, Gemma made $34.00 more money than Leah.

____ inches = ____ feet = ____ yards

Answers

Answer:

126 inches = 10.5 feet = 3.5 yards

42 in = 3.5 ft = 1.1667 yds

2.5 ft = 30 in = 0.8333 yds

1.5 yds = 54 in = 4.5 ft

42+30+54= 126 in

3.5+2.5+4.5= 10.5 ft

1.5+0.8333+1.1667= 3.5 yds

A store clerk sold 25 Mathematics books and 10 English books for a total of $855. If she had sold 10 Mathematics books and 40 English books, she would have got $135 more. form a pair of linear equations and calculate the price of each book.

Answers

Answer:

855+135=990

90x11=990

10x11=110

25x11=275

110+275=385                                                                                                             990+110=1100 

385+1100=1485

1485/11=135

the math books was $11 each so all to gether it is $275.      

the english books was $65 each so all to gether it is 715.

275+715=990

Step-by-step explanation:

The required price of a Mathematics book is $27 and the price of an English book is $18.

What is the equation model?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Let's assume that the price of a Mathematics book is x dollars and the price of an English book is y dollars. Then we can form two equations based on the given information:

Equation 1: 25x + 10y = 855

This equation represents the total amount earned by selling 25 Mathematics books and 10 English books for $855.

Equation 2: 10x + 40y = 990

This equation represents the total amount that would have been earned by selling 10 Mathematics books and 40 English books for $135 more than the original total.

To solve for x and y, we can use elimination or substitution. Let's use elimination:

Multiplying Equation 1 by 4, we get:

100x + 40y = 3420

Now, we can subtract Equation 2 from this equation to eliminate y:

90x = 2430

x = 27

Substituting x = 27 into Equation 1, we can solve for y:

25(27) + 10y = 855

675 + 10y = 855

10y = 180

y = 18

Therefore, the price of a Mathematics book is $27 and the price of an English book is $18.

Step-by-step explanation:

Set up the equation 5x+7x+9x=2100 and solve for x:

5x+7x+9x=2100

21x=2100

x=100

Now multiply the proportion by 100:

In a decorative figurine shop, it takes of an hour to paint 8
identical ceramic figurines. How long does it take to paint one
figurine? At the same rate, how long would it take to paint 12
figurines?

Answers

The time it would take to paint one figurine is 0.125 hour.

The time it would take to paint 8 figurine is 1.5 hours.

The first step is to determine the average rate. Average rate is the total ceramic figurines painted divided by the total time.

Average rate = 8 /1 = 8 figurines / hour

In order to determine how long it would take to paint 8 figurines, divide 12 by the  average rate.

1 / 8 = 0.125 hour

In order to determine how long it would take to paint 8 figurines, divide 12 by the  average rate.

12 / 8 = 1.5 hours
