Answer:

0.020405

Step-by-step explanation:

We solve this question, using z score formula.

z-score formula =

z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

From the above question:

x = 1400, μ = 950, σ = 220

z = 1400 - 950/220

z = 2.04545

Determining the probability from Z-Table:

P(z = 2.04545) = P(x<1400) = 0.97959

P(x>1400) = 1 - P(x<1400)

= 1 - 0.97959

= 0.020405

Therefore, the probability of a student reading at more than 1400 words per minute after finishing the course is 0.020405

Answer:

Math tells me 8,302/12=691.833...

Step-by-step explanation:

Answer:

[tex]\frac{6}{10}[/tex]

Step-by-step explanation:÷

convert 0.7 to a fraction so [tex]\frac{7}{10}[/tex]

and convert the mixed number to a fraction [tex]\frac{7}{6\\}[/tex]

now divide them

[tex]\frac{7}{10}[/tex] ÷  [tex]\frac{7}{6\\}[/tex]

[tex]\frac{7}{10}[/tex] x [tex]\frac{6}{7}[/tex]

so 7 and 7 cancel out so 1 over 10 and 6 over 1 now multiply and you get

6 over 10

Answer:

x = 5/2

Step-by-step explanation:

Solve for x:

(5 x)/2 = 25/4

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (5 x)/2 = 25/4 by 2/5:

(2×5 x)/(5×2) = 2/5×25/4

Hint: | Express 2/5×5/2 as a single fraction.

2/5×5/2 = (2×5)/(5×2):

(2×5)/(5×2) x = 2/5×25/4

Hint: | Express 2/5×25/4 as a single fraction.

2/5×25/4 = (2×25)/(5×4):

(2×5 x)/(5×2) = (2×25)/(5×4)

Hint: | Cancel common terms in the numerator and denominator of (2×5 x)/(5×2).

(2×5 x)/(5×2) = (5×2)/(5×2)×x = x:

x = (2×25)/(5×4)

Hint: | In (2×25)/(5×4), divide 25 in the numerator by 5 in the denominator.

25/5 = (5×5)/5 = 5:

x = (2×5)/4

Hint: | In (2×5)/4, divide 4 in the denominator by 2 in the numerator.

2/4 = 2/(2×2) = 1/2:

Answer:  x = 5/2

Answer:

60 muffins

Step-by-step explanation:

Muffins = 6 per package

Cookies = 20 per package

His Baker realized they sold the same amount of muffins and cookies yesterday

What is the minimum amount of muffins that were sold yesterday?

To find the minimum amount of muffins sold, find the lowest common multiple of 6 muffins per package and 20 cookies per package

6 muffins per package = 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84

20 cookies per package = 40, 60, 80, 100, 120

The lowest common multiple of of 6 muffins per package and 20 cookies per package is 60.

Therefore, the minimum amount of muffins sold yesterday was 60 muffins.

Answer:

453.6

Step-by-step explanation:

226.8 x 2 = 453.6

The mass of two rolls of quarters is 453.6 grams.

It is required to find the mass of two rolls of quarters.

The branch of mathematics dealing with the properties and manipulation of numbers. a science that deals with the addition, subtraction, multiplication, and division of numbers. Fractions, decimals, percentages, fractions, square root, exponents, and other arithmetic operations are used to achieve mathematical simplifications.

Given:

One quarter has a mass of 5.67 grams

mass of each quarter=40 quarters

The mass of 80 quarters will be 80 times the mass of 1 quarter:

 80 × 5.67 g = 453.6 g

Hence, the mass of two rolls of quarters is 453.6 grams.

Answer:

Given: Surface Area  = Volume

2(lb + bh + hl) = lbh

2(33 + 3x + 11x) = 33x

66 + 6x + 22x = 33x

66 + 28x = 33x

66 = 5x

Answer:

g(h(x)) = 54x + 71

Step-by-step explanation:

Step 1: Define

g(x) = -6x + 5

h(x) = -9x - 11

Step 2: Find g(h(x))

g(h(x)) = -6(-9x - 11) + 5

g(h(x)) = 54x + 66 + 5

g(h(x)) = 54x + 71

Answer:

0=0

or as separate equations:

y=1/2

X=4y+2

Explanation:

If we solve your system by elimination:

x−4y=2;4x−16y=8 -->

Multiply the first equation by -4,and multiply the second equation by 1.

−4(x−4y=2)

1(4x−16y=8)

Becomes:

−4x+16y=−8

4x−16y=8

Add these equations to eliminate x:

Answer:

Step-by-step explanation:

A pencil in the picture shows a segment with a definite length.

We may get confused with the difference in a line and segment.

A line is defined by a line of points that extends infinitely.

That means both the ends of a line are not defined.

But a segment is a part of line which has a definite length between two defined ends.

Therefore, unsharpened pencil defines the term line segment which is a defined term.

Answer:

The unsharpened pencil suggests the term line segment, which is a defined term.

Does it need to be solved too?

Answer:

The length is 26 feet and the width is 23 feet

Step-by-step explanation:

Let l represent the length of the rectangle.

The width can be represented by l - 3, since it is 3 feet less than the length

Set up an equation:

l + l + (l - 3) + (l - 3) = 98

Add like terms and solve for l:

l + l + (l - 3) + (l - 3) = 98

4l - 6 = 98

4l = 104

l = 26

So, the length is 26 feet.

Since the width is l - 3, we can plug this in for l to find the width:

l - 3

26 - 3

= 23

So, the length is 26 feet and the width is 23 feet

The equation 7 = 2y + 9 is equivalent to -3 = 2y + 1 and  -2 = y – 1 option (a) and (c) are correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that equation:

7 = 2y + 9

After simplification:

2y = 7 - 9

2y = -2

y = -1

a.) -3 = 2y + 1

After simplification:

2y = -3 - 1

2y = -4

y = -1

b.) 8 = 9y - 1

After simplification:

9y = 1 + 8

9y = 9

y = 1

c.) -2 = y – 1

After simplification:

y = -2 + 1

y = -1

d.) -4 = 2y + 6

After simplification:

2y = -4 - 6

2y = -10

y = -5

Thus, the equation 7 = 2y + 9 is equivalent to -3 = 2y + 1 and  -2 = y – 1 option (a) and (c) are correct.
