Answer: 1.54

Step-by-step explanation:

Given that :

Z = normal random variable

Area to the left of z = 0.9382

For a random normal distribution ;

P(Z < x) = 0.9382

Using the Z table (standard normal distribution table) ;

Locating the probability value (0.9382) on the table and picking the intersecting z value both horizontally and vertically :

Horizontal value = 1.5

Vertical value = 0.04

Horizontal + vertical = (1.5 + 0.04) = 1.54

[tex]x \leqslant cy + D[/tex]

Subtract sides D

[tex]x - D \leqslant cy + D - D[/tex]

[tex]x - D \leqslant cy[/tex]

Divide sides by c

[tex] \frac{x - D }{c} \leqslant \frac{cy}{c} \\ [/tex]

[tex] \frac{x -D}{c} \leqslant y \\ [/tex]

Answer:

Yes,

Step-by-step explanation:

Because every "x" Value corresponds to exactly one "y" value.

Yes, the relation is a function.

A relation is a function if it has only One y-value for each x-value.

The given relation is {(3,2), (1, -2), (2, -4), (3, -2)}.

We need to check whether the relation is a function or not.

A function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set.

As we observe the given relation three comma two, one comma minus two, two comma minus four comma three comma minus two.

Yes, the given relation is a function because there is no x value is repeated. Every y value has an unique x value.

Hence, the relation is a function.

Answer: 0.375

Step-by-step explanation:

Given: The difference between actual and predicted weekly sales of a company follows a uniform distribution between -$4000 and $4000.

Probability density function: [tex]f(x)=\dfrac{1}{b-a}=\dfrac{1}{4000-(-4000)}=\dfrac{1}{8000}[/tex]

The probability that the actual sale is within $1500 of the predicted sale = [tex]\int^{1500}_{-1500}f(x)dx=\int^{1500}_{-1500}\dfrac{1}{8000}dx=\dfrac{1}{8000}[x]^{1500}_{-1500}\\\\= \dfrac{1}{8000}(1500-(-1500))\\\\= \dfrac{1}{8000}(3000)=0.375[/tex]

Hence, Required probability =0.375

Answer:

y = -3x + 30

Step-by-step explanation:

A great website to use for graphing is desmos. You first graph the starting 2 points, turn it into a line connecting it, then make an equation. You should get y = -3x + 5, so when we look for something parallel it should have the same slope. I then put into the graph every equation along with the dot (11,-3) and looked to see which intersected.

Q: -10x-(-4)=14

A: x=-1

Process:

-Subtracting a negative is just like adding 10x+4=14

-Subtract 4 from both sides -10x=10

Divide -10 from both sides x=-1

Answer:

the first one makes the most sense

Answer:

x = 1, y = 4

Step-by-step explanation:

Given

(2x + 3) + i(x - 2y) = 5 - 7i

Equate the real parts on both sides

2x + 3 = 5 ( subtract 3 from both sides )

2x = 2 ( divide both sides by 2 )

x = 1

Equate the coefficients of the imaginary terms

x - 2y = - 7 , that is

1 - 2y = - 7 ( subtract 1 from both sides )

- 2y = - 8 ( divide both sides by - 4 )

y = 4

Answer: The first 3 are functions. The last one is not a function

Step-by-step explanation: What you can do is the line test. If you draw a line through it, the line shouldn't touch the arrow twice. Like the last one, it touches the line twice, so it is not a function

Answer:

Step-by-step explanation:

The value X° where x is non zero number will give a value of 1 because any value raise to the power of zero gives 1.

For example if X = 2, 2° = 1

For the expression 0^x, this will result into zero for any positive power of x. Let x be 3 for example,

0³ = 0×0×0

0³ = 0

Also if x = 4

0⁴ = 0×0×0×0 = 0

Therefore, no matter the value of x, rge value 0^x will return back zero.

For 0^0 this value is an indeterminate function i.e we cannot determine the the value. The value cannot return Amy positive or negative real number on the number line. Hence 0^0 is indeterminate.

Answer:

14/25

Step-by-step explanation:

If the denominators are the same, subtract the numerators.

21/25-7/25=14/25

14 and 25 do not have any similar factors greater than 1, so we keep it as 14/25.

Answer:

A; x + 15 = 90

B: x = 75

Step-by-step explanation:

A: complementary angles are angles that add up to 90 degrees. This means that x and 15, the two angles that are complementary, will add up to 90:

x + 15 = 90

B: For B, you just need to solve the equation for x:

1. x + 15 = 90

2. x = 75

Step 1 is the given equation

In step 2, 15 was subtracted from both sides
