in a standard normal distribution, the probability that z is greater than zero is
Answer:
50%
Step-by-step explanation:
The distribution is symmetrical about the y-axis.
The probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.
What is Probability?The branch which deals with the occurrence of a random event is known as probability.
The area under the curve to the right of z = 0 is equal to the area under the curve to the left of z = 0. So the standard normal distribution is symmetric about the mean of zero
As the total area under the curve is equal to 1, each of these areas must be 0.5 or 50%.
In a standard normal distribution, the probability that z is greater than zero is 0.5, or 50%.
Therefore, the probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.

Which is the correct label of the parallel lines? Parallel lines a and b are shown. Points A and B lie on line a while points C and D lie on line b. The letters a and b are separated by two vertical lines. There is a horizontal line with arrows on either end over the letters A A. There is another horizontal line with arrows on either end over the letters C B. A vertical line with a horizontal line intersecting it at the bottom separates the two pairs. There is a horizontal line over the letter A with one arrow on the right end. There is a horizontal line over the letter B with one arrow on the right end. The letters are separated by two vertical lines. There is a horizontal line with arrows on either end over the letters A B.

a || b will be the correct label for the parallel line so option (A) will be correct.
What are parallel lines?Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.
Parallel lines are those lines in which slopes are the same and the distance between them remains constant.
Given the two lines a and b as parallel.
If we want to show any two lines as parallel then we use |the | sign in between them.
Now in the given figure, A B C D are points on lines a and b so they will not be used to show parallel lines.
Hence "a || b will be the correct label for the parallel line".

Larry Gold’s gross pay for this week as a stock clerk for Hensley’s is $375.15. He is single and claims 2 allowances. Using the percentage method of withholding, what is his withholding for federal income tax?
Larry gold is withholding $22.38 in federal tax income.
The federal government and the majority of states in the US impose income taxes.
Applying a tax rate to taxable income, which is the entire income less permissible deductions, yields the income taxes, which may rise as income rises. Income is a broad concept. Estates and trusts may be subject to taxation on income that has not been dispersed, in addition to individuals, corporations, and the government. (With a few exceptions for Federal income taxation) Partnerships are not subject to taxation; however, the partners of a partnership are. While nonresidents are solely subject to local taxes, residents and citizens are subject to worldwide taxes. Numerous credit kinds lower taxes, and some credit types may even be more than taxes before credits. There is an alternative tax.Given that Larry gross pay for this week is $375.15
Now we know from the income tax table that the withheld tax is calculated by calculating 6% of the gross pay when there are 2 allowances.
Tax = 6% of 375.15 = 22.38
Hence the withholding for federal income tax is $22.38 .

The value of y is directly proportional to the value of x. When x=3.5, the value of y is 14. What is the value of y when x = 28?
Answer:
x = 7
Step-by-step explanation:
y = 14
14 x 2 = 28
Therefore:
3.5 x 2 = 7
Value of y is 112 when value of x is 28
Given that;
Value of y is 14 when x = 3.5
Find:
Value of y when value of x = 28
Computation:
We know that, y is directly proportional to x
So,
[tex]Value\ of\ y = 14[\frac{28}{3.5} ] \\\\Value\ of\ y = 14[8]\\\\Value\ of\ y = 112[/tex]

Tomas and Tasha were hiking at a speed of 3.5 mph on their way back they were tired and their speed was 2 mph how long was the route if the way back took them 1 hour and 30 minutes longer (in miles)
Answer: 7 miles
Step-by-step explanation:
To get the length of the route use the expression for speed,
Distance = Speed × Time
Length of the route is 7 miles.
It's given in the question,
Speed of Tomas and Tasha initially = 3.5 mph
Therefore, distance travelled by both with the speed of 2 mph one way will be,
Distance = 3.5t [Here, t = time ]
Speed of both while coming back = 2 mph
And the time taken = t + (1 hour 30 minutes)
= (t + 1.5) hours
Therefore, distance travelled while coming back = Speed × Time
= 2(t + 1.5)
Since, length of the route is same both ways,
3.5t = 2(t + 1.5)
3.5t = 2t + 3
3.5t - 2t = 3
1.5t = 3
t = 2 hours
Now substitute the value of t in the expression to get the distance of the route,
Distance = 3.5t
= 3.5 × 2
= 7 miles
Therefore, route was 7 miles long.
