Answer:
Time and a half pay is 50% more than an employee's regular rate of pay. For every hour of overtime an employee works, you must give them their regular rate of pay plus half of that. To calculate an employee's overtime rate of pay, multiply their regular rate by 1.5.

Angle R and 92 are supplementary angles. What equation can you use to solve for R?
R+180=92
R+90=92
R+92=180
R+92=90
180+92=R
Answer:
Your answer is R+92=180
Step-by-step explanation:
Supplementary means angles that add up to 180, so R+92=180 has to be correct.

What is the lowest whole number for hypotenuse c when using the formula [tex]\sqrt{a^2+b^2}[/tex] and a = b?
9514 1404 393
Answer:
0
Step-by-step explanation:
If a=b, you are asking for a whole number c such that ...
c = √(a² +a²) = a√2
If 'a' is a whole number, the only whole numbers that satisfy this equation are ...
c = 0 and a = 0.
0 = 0×√2
The lowest whole number c such that c = √(a²+b²) and a=b=whole number is zero.
__
√2 is irrational, so there cannot be two non-zero whole numbers such that c/a=√2.
_____
Additional comment
If you allow 'a' to be irrational, then you can choose any value of 'c' that you like. Whole numbers begin at 0, so 0 is the lowest possible value of 'c'. If you don't like that one, you can choose c=1, which makes a=(√2)/2 ≈ 0.707, an irrational number. The problem statement here puts no restrictions on the values of 'a' and 'b'.
The public relations officer for a particular city claims the average monthly cost for childcare outside the home for a single child is $600. A potential resident is interested in whether the claim is correct. She obtains a random sample of 14 records and computes the average monthly cost of this type of childcare to be $589 with a standard deviation of $40. Perform the appropriate test of hypothesis for the potential resident using . Approximate the p-value for the test in (a).
Answer:
Since the calculated value of z= -1.0198 does not lie in the critical region z = ± 1.96 the null hypothesis is accepted and it is concluded that the average monthly cost for childcare outside the home for a single child is $600.
P- value ≈ 0.307823 which supports the null hypothesis .
Step-by-step explanation:
The null and alternate hypotheses are
H0: u = $600 the average monthly cost for childcare outside the home for a single child is $600.
against the claim
Ha: u ≠ $600 the average monthly cost for childcare outside the home for a single child is not equal to $600.
The significance level is set at 0.05
3) The critical region is z = ±1.96
4) The test statistic
Z=x- u /s/√n
z= 589-600/40/√14
z= -11/10.7681
z= -1.0198
6) Conclusion
Since the calculated value of z= -1.0198 does not lie in the critical region z = ± 1.96 the null hypothesis is accepted and it is concluded that the average monthly cost for childcare outside the home for a single child is $600.
P- value ≈ 0.307823 which supports the null hypothesis .
What is the slope of the line below? If necessary, enter your answer as a
fraction in lowest terms, using the slash ( 1 ) as the fraction bar. Do not enter
your answer as a decimal number or an equation.
The slope of line shown in the graph is 1.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We have two points from the graph as (8, 8) and (5, 5)
So, the slope of line
Slope = (5- 8)/ (5-8)
slope= (-3)/ (-3)
slope = 1
Also, rise 3 units and run 3 units
Then, slope= Rise/ Run
slope= 3/3
Slope= 1
This, the required slope is 1.

a planter is shaped like a right rectangular prism its height, h is 5 4/5 inches. The length, L is 14 1/2 inches ,and its width, W is 3 1/2 inches. When determining of the planter, which statements are correct
Answer:
There appears to be some part of the question missing. Assuming it asks about the volume, the volume is:
Step-by-step explanation:
The volume of a right rectangular prism may be calculated using the formula:
whl, where w is width, h is height and l is length.
In this case it is hlw or (5.8*14.5*3.5) = 294.35 cubic inches.
Answer: 8 ft
Step-by-step explanation:To find the correct answer, use the formula, V=l×w×h. Substitute 48 for the volume, 2 for width, and 3 for height. Then, use a related division equation to find the length.
48 = l × 2 × 3
48 = l × 6, so 48 ÷ 6 = l
8 = l
The length of the planter box is 8 feet.

Answer:242
Step-by-step explanation:
bc you have 25 to49 adults divide and subtracts & you get 242 , hope this helps !
83 people out of 400 people would be expected to be age 40-44.
What is probability?Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
As, 400 people choose sauce B.
In the given table there 302 people who choose sauce B, in which 63 people belongs to group 40-44
So, 63/302= x/400
302*x=63*400
x=83.
Hence, 83 people out of 400 belongs to group 40-44 who choose sauce B.

The water level at a local pier rises and falls with the tide. Yesterday, the maximum depth of the water at the pier was 8 feet, and the minimum depth was 4 feet. High tide occurred at 12:00 am and low tide occurred at 12:20 pm. Which function models the depth, in feet, of the water at the pier yesterday, as a function of the time t in minutes past high tide?
Answer: C, Bottom Left
Step-by-step explanation:
The function that models the depth, in feet, of the water at the pier yesterday, as a function of the time t in minutes past high tide is: 2 cos(π/740t)+6.
What is function model?Amplitude
A = 8 - 6
A = 2 ft
Average depth
A = (4 + 8)/2
A = 6 ft
Hence:
A+B=8
-A+B=4
1/2t=12×60×20=740
w=2π/t=π740
When t=0
d=2sin4+6=8
4=π/2
Hence:
d(t)=2 sin(π/740t + 4)+6
2 cos(π/740t)+6
Therefore the function that models the depth, in feet, of the water at the pier yesterday, as a function of the time t in minutes past high tide is: 2 cos(π/740t)+6.

Composite scores on the ACT are normally distributed with a mean of 21 and a standard deviation of 5. find the Z score for a student that gets a 31
Answer:
[tex]Z = 2[/tex]
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 21 and a standard deviation of 5.
This means that [tex]\mu = 21, \sigma = 5[/tex]
Find the Z score for a student that gets a 31
This is Z when X = 31. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{31 - 21}{5}[/tex]
[tex]Z = 2[/tex]

Step-by-step explanation:

Which of a to d has no solution
(a)[tex]6m \le - 36[/tex] and [tex]m + 24 > 20[/tex]
We have: [tex]m + 24 > 20[/tex]
Sole for m
[tex]m >20 - 24[/tex]
[tex]m >-4[/tex]
[tex]6m \le - 36[/tex]
Divide by 6
[tex]m \le -6[/tex]
So, we have:
[tex]m \le -6[/tex] and [tex]m >-4[/tex]
[tex]m \le -6[/tex] implies that: m = -6,-7,-8,-9.....
