Answer:

=42t+16

Step-by-step explanation:

=2t+(4)(4)+(4)(10t)

=2t+16+40t

=2t+16+40t

=(2t+40t)+(16)

=42t+16

Simplify the expression

2t + 4(4 + 10t)

Simplifying

y = 2t4 + -10t2 + 13

Reorder the terms:

y = 13 + -10t2 + 2t4

Solving

Solving for variy = 13 + -10t2 + 2t4

able 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying

y = 13 + -10t2 + 2t4

Hence the information I've given you, we can now state that the answer is

42 t  +  16  

Answer:

49 and 36

Step-by-step explanation:

49 - 36 = 13

49 + 36 = 85

Answer:solving we get y=6  x+y=85

x-y=13

add the equations

2x=98

x=98/2

x=49

85-49=36

the numbers are 49 and 36

Answer:

His daughter received $ 1,271,760.

Step-by-step explanation:

Given that a man had $ 10,072,540 with him, and he gave $ 4,836,080 to his wife, $ 3,964,790 to his son and the rest to his daughter, to determine how much money was received by the daughter, the following calculation must be performed:

10,072,540 - 4,836,080 - 3,964,790 = X

5,236,460 - 3,964,790 = X

1,271,670 = X

Thus, his daughter received $ 1,271,760.

Answer:

x=122°

Step-by-step explanation:

sum of all interior angles in a quadrilateral = 360°

then ,

119+105+78+m = 360

m = 58

....

m+ x = 180 ( linear pair)

58+x = 180

x = 122

Answer:

Y=3x+7

y=5x+8

3x + 7 = 5x + 8

-1 = 2x

x = -1/2

y = 3(-1/2) + 7

y = -3/2 + 7

y = 5.5

x = -0.5 ; y = 5.5

Answer:

x = [tex]-\frac{1}{2}[/tex] y = 5.5

Step-by-step explanation:

substitution method

3x + 7 = 5x + 8

subtract 3x from both sides

7 = 2x + 8

subtract 8 from both sides

-1 = 2x

divide each side by 2

x = [tex]-\frac{1}{2}[/tex]

substitute the x in either equation

y = 3(-1/2) + 7

y = -1.5 + 7

y = 5.5

or

y = 5(-1/2) + 8

y = -2.5 + 8

y = 5.5

Answer:

[tex]\frac{2}{5}[/tex]

Step-by-step explanation:

[tex]\frac{3}{5} *\frac{2}{3}\\=\frac{3*2}{5*3}[/tex]

The 3 in the numerator and the 3 in the denominator cancel out

[tex]= \frac{2}{5}[/tex]

Answer:

Answer:

B

Step-by-step explanation:

We have that for a normal distribution, the value of z can be calculated using the following formula:

z = (x - m) / sd

where x is the value to evaluate, m the mean and sd the standard deviation, we have those values x = 15.3, m = 17.4 and sd = 3.2

if we replace we have:

z = (15.3 - 17.4) /3.2

z = -0.65625

if we round to 2 decimal places, it would be -0.66, that is, the answer is B.

A Z-score helps us to understand how far the data is from the mean. The z-score of the given length of this fish is -0.66. The correct option is B.

A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,

z-score = (x-μ)/σ

Where Z is the Z-score,

X is the data point,

μ is the mean and σ is the standard variable.

Given that the length of a species of fish is normally distributed, with a mean(μ) and the standard deviation(σ) is 17.4 cm and 3.2 cm. Therefore, the z-score of the length of this fish is,

z-score = (x-μ)/σ

            = (15.3 - 17.4) / 3.2

            = -2.1/3.2

            = -0.65625

            = -0.66

Hence, the z-score of the given length of this fish is -0.66.
