Answer: 1/13, 1/4, 1/52, 3/4
Step-by-step explanation:
There are 52 cards in a standard playing deck. There are 4 of each suit (spade, club, heart, diamond) there are also 4 of each number, jack, queen, king.
The chance of you drawing a jack: 4 jacks in a card deck of 52, so 1/13, similar with the spades there are 13 spades in 52 cards, jack of spades there's only 1 in the entire deck, and not a spade there are 13 spades and 52 cards. After that you just simplify the results.
After multiplying pay rate and total hours worked by Alani we get her total earning as $296.
What is multiplication ?
- Mathematicians use multiplication to calculate the product of more than two numbers. It is a fundamental operation in mathematics that is frequently utilized in everyday life.
- When it is necessary to merge groups of similar sizes, we utilize multiplication.
- The fundamental concept of complement system the same number is represented by the process of multiplication.
- The results of multiplying two or maybe more numbers are known as both the products of those numbers, and the factors those are multiplied are referred to as the factors.
- Recurrent addition of the identical number is made easier by multiplying the numbers.
Alani makes $8/h for working upto 40hours.
If she works for 37 hours then her pay-rate would be $8/hr.
Therefore, we will multiply 8 by 37.
Alani earns $296.

The complete question you are looking for might be :
Alani has a summer job as a lifeguard. She makes $8/h for up to 40 h each week. If she works more than 40 h, she makes 1.5 times her hourly pay, or $12/h, for each hour over 40 h. 1. How much will Alani earn if she works: 37 hours?
Answer:
Angle x = angle 115°.
Step-by-step explanation:
Given : Two parallel lines are crossed by a transversal.
To find : What is the value of x.
Solution : We have given Two parallel lines are crossed by a transversal.
Corresponding angles : A pair of angle that lies on the same side of the transversal line one lies on interior angle and other lies on exterior.
Corresponding angle are equal.
Then , angle x = angle 115 are corresponding.
Therefore, angle x = angle 115.
Answer:
6 is a whole number.
is approximately equal to 0.333, but this is a repeating decimal.
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
H0: µ = 7.2
For the alternative hypothesis,
H1: µ ≠ 7.2
This is a two tailed test.
Since the population standard deviation is given, the test statistic would be the z score determined from the normal distribution table. The formula is
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = population standard deviation
n = number of samples
From the information given,
µ = 7.2
x = 7.3
σ = 0.8
n = 250
z = (7.3 - 7.2)/(0.8/√250) = 1.976
Test statistic is 1.976
