D Question 13 3 pts [True or False] For a standardized normal distribution, Z, the probability that Z is greater than 1.50 is less than the probability that Z is greater than 2.50. True O False < Prev
For a standardized normal distribution, Z, the probability that Z is greater than 1.50 is less than the probability that Z is greater than 2.50. False, is the correct statement regarding the given statement.
In statistics, the standardized normal distribution is a normal distribution with a mean of zero and a standard deviation of one. It is also known as the standard normal distribution. The distribution is entirely defined by its mean and standard deviation. For example, any normal distribution can be standardized by subtracting its mean and dividing by its standard deviation.This distribution is a continuous probability distribution.
A continuous probability distribution is a probability distribution that assigns probabilities to an infinite number of possible outcomes that are not countable. These probabilities are expressed as the area under the curve in a continuous probability distribution. The total area under the curve of a continuous probability distribution is always equal to one.
The statement given "For a standardized normal distribution, Z, the probability that Z is greater than 1.50 is less than the probability that Z is greater than 2.50" is false.
This is because the normal distribution curve is a symmetrical curve and the probability of being greater than a value of 1.50 or 2.50 is the same.
Therefore, the probability of Z being greater than 1.50 is the same as the probability of Z being greater than 2.50. The answer is False.

What is the value of x in the product of powers below?
6 Superscript 9 times 6 Superscript x = 6 squared
Negative 11
negative 7
7
11
Answer:
Step-by-step explanation:
We can start by simplifying the left side of the equation using the product of powers rule, which states that when we multiply two powers with the same base, we can add their exponents.
6^9 * 6^x = 6^2
Now we can use the rule to add the exponents on the left side of the equation:
6^(9+x) = 6^2
Since the bases are the same, we can equate the exponents:
9 + x = 2
Subtracting 9 from both sides gives us:
x = -7
Therefore, the value of x in the product of powers equation is -7.

A system of linear equations is given by the tables. One of the tables is represented by the equation y = - 1/3x + 7. x y 0 5 3 6 6 7 9 8 x y -6 9 -3 8 0 7 3 6 The equation that represents the other equation is y = x + . The solution of the system is ( , )
The solution of the system is (- 3, 8).
A system of linear equations is given by two tables. The first table is represented by the equation y = - 1/3x + 7, while the second table is not represented by any equation.
However, we can determine the equation of the second table by finding the slope of the line that passes through the points (0, 5) and (3, 6).slope = change in y/change in x= (6 - 5)/(3 - 0)= 1/3
Since the slope of the line is 1/3 and it passes through the point (0, 5), we can use point-slope form to find the equation of the line. Using point-slope form,
the equation of the second table is:y - 5 = 1/3(x - 0)y = 1/3x + 5To solve the system of equations, we can use substitution. We can substitute y = - 1/3x + 7 into the equation y = x + 5:y = x + 5- 1/3x + 7 = x + 5- 1/3x = - 2x = 6x = - 3
The solution for x is x = - 3. We can use this value to find the solution for y by substituting into either of the equations. Using y = - 1/3x + 7, we get:y = - 1/3(- 3) + 7= 1 + 7= 8

A truck can be rented from Acme
Truck Rental for $80 per week plus $0.28 per mile.
How many miles can be driven if you have at most $100 to spend on truck rental.
Answer: 71.429 miles
Step-by-step explanation:
The charge for the rental truck can be represented by the equation: y= 0.28m+80
m is the miles driven
y is the total cost
Plug in 100 for y because that’s how much you have to spend
100=0.28m+80
-80 -80
20=0.28m. Divide both sides by 0.28
71.429 miles

solve for k: 31 - 3k = 10
Answer:
k = 7
Step-by-step explanation:
Step 1: Write equation
31 - 3k = 10
Step 2: Solve for k
Subtract 31 on both sides: -3k = -21Divide both sides by -3: k = 7Step 3: Check
Plug in k to verify it's a solution.
31 - 3(7) = 10
31 - 21 = 10

Find the measure of angle MKN.
Answer:
m∠MKN = 61°
Step-by-step explanation:
Since KN is a perpendicular bisector, m∠NKM and m∠MKJ have to add up to 90°.
Step 1: Set up equation
6x + 7 + 3x + 2 = 90
Step 2: Solve for x
Combine like terms: 9x + 9 = 90Subtract 9 on both sides: 9x = 81Divide both sides by 9: x = 9Step 3: Find m∠MKN
m∠MKN = 6x + 7
m∠MKN = 6(9) + 7
m∠MKN = 54 + 7
m∠MKN = 61°
Answer:
61
Step-by-step explanation:
Since JKL is a straight line, it equals 180
JKM + MKN + NKL = 180
3x+2 + 6x+7 + 90 = 180
Combine like terms
9x+99 = 180
Subtract 99 from each side
9x+99-99= 180-99
9x =81
Divide each side by 9
9x/9 = 81/9
x=9
We want MKN
6x+7 = 6*9 +7 = 54+7 = 61

The states that x2 + y2 = r2. By , we have [r cos(θ)]2 + [r sin(θ)]2 = r2. Applying the , the equation can be written as r2 cos2(θ) + r2 sin2(θ) = r2.

factor 144abc−108ab . if the expression cannot be factored, write cannot be factored.
The factored form of the expression 144abc - 108ab is 36ab(4c - 3).
To factor the expression 144abc - 108ab, we can first identify the common factors of the terms.
In this case, we can see that both terms have a common factor of 36ab:
144abc - 108ab = 36ab(4c - 3)
So, the expression can be factored as 36ab(4c - 3).
This means that the expression is not prime and can be simplified further by factoring out the common factor.
By factoring out the common factor of 36ab, we obtain the simplified form of the expression as 36ab times the binomial (4c - 3).

Given the values a = 0, b = 0, and c = a + b, we are asked to find the values of expressions involving these variables: C = 2017(b + c), D = 2018, and E = 2019.
Given a = 0 and b = 0, we can substitute these values into the expressions involving c.
Since c = a + b, we have c = 0 + 0, which simplifies to c = 0.
Now we can evaluate the expressions:
A) 2015: No information is provided to determine the value of 2015. We cannot evaluate this equation.
B) 2016: Similarly, no information is provided to determine the value of 2016. We cannot evaluate this expression.
