To solve the expression, the steps are add 19 and multiply by 5
<h3>How to solve the expression</h3>
Given the equation;
-3 = -19 + d/5
First,
Collect like terms
-3+ 19 = d/5
Add the values on the left side
We have
16 = d/5
Cross multiply
16 × 5 = d
We then have
d = 80
Thus, to solve the expression, the steps are add 19 and multiply by 5

Answer:
2 and 3/4
11/4
Step-by-step explanation:
an improper fraction is any fraction with a numerator bigger then the denominator.
a mixed number is the "proper" version of an improper fraction.
the fraction 11/4 as a mixed number is 2 and 3/4.
to make an improper fraction a mixed number, find out how many times the denominator goes into the numerator. whatever you have left that didn't make 1 whole, turns into the fraction .
hope this helped
Answer:
I just solved a question similar to this
Let's understand it
It's saying she got 660 or it is that her weekly pay is 660
So now let weekly pay which is P be 660
Hence the formulae is given
It's 480 + 18 (h – 30) = 660
Now its just boring calculation
If you mark it brainleist I will do the calculation for you wink wink
Never mind
480 + 18 (h – 30) = 660
18 (h – 30) = 660-480
18 (h – 30) = 120
(h – 30) = 120/18
(h – 30) = 6.6
h = 6.6+30
h= 36.6
So dam the Judy lady worked for 36.6 hours
Answer:
(c) if n is large, then the sampling distribution of the sample mean can be approximated closely by a normal curve.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sampling distribution of the sample mean, with a large sample size, can be approximated to a normal distribution with mean
and standard deviation
.
This is valid no matter the shape of the population.
So the correct answer is:
(c) if n is large, then the sampling distribution of the sample mean can be approximated closely by a normal curve.
Answer:

Step-by-step explanation:
Using the division rule when dealing with exponents

meaning that when we divide exponents that have the same base but different powers we can subtract the power of the bottom exponent from the top exponet.
so using that we are going to do 2, 4 and 9



Combine all the terms and we get
