which is an equivalent expression for 18c + 144
The required expression that is equivalent to 18c + 144, is 18(c + 144).
Given that,
To determine the equivalent expression to 18c + 144.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The given expression,
= 18c +144
Taking 18 commons from the above equation,
= 18(c + 18)
Thus, the required expression that is equivalent to 18c + 144, is 18(c + 144).

Out of 10 marbles in a bag, 2 of them are blue. If you drew a marble at random 40 times, replacing it each time, how many times would you expect to draw a blue marble?
Answer:
8
Step-by-step explanation:
8 times would you expect to draw a blue marble.
What is Probability?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
Given:
Total marbles = 10
Blue marbles=2
Number of times= 40
So, the number of times would you expect to draw a blue marble
=2/10 *40
=80/10
=8
Hence, 8 times would you expect to draw a blue marble.

Find a 95% confidence interval for the true population proportion.
In a survey of 765 employees of a large company, 30% said that they had high job satisfaction.
Answer:
The 95% confidence interval for the true population proportion is (0.27, 0.33).
Step-by-step explanation:
The (1 - α)% confidence interval for population proportion of is:
[tex]CI=\hat p \pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]
The information given is:
[tex]\hat p=0.30\\n=765\\\text{Confidence level}=95\%[/tex]
The critical value of z for 95% confidence level is, 1.96.
Compute the 95% confidence interval for the true population proportion as follows:
[tex]CI=\hat p \pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]
[tex]=0.30\pm 1.96\times\sqrt{\frac{0.30(1-0.30)}{765}}\\\\=0.30\pm 0.0325\\\\=(0.2675, 0.3325)\\\\\approx (0.27, 0.33)[/tex]
Thus, the 95% confidence interval for the true population proportion is (0.27, 0.33).

Step-by-step explanation:
Let's solve your equation step-by-step.
6x+78=180
Step 1: Subtract 78 from both sides.
6x+78−78=180−78
6x=102
Step 2: Divide both sides by 6
6x/6=102/6
x=17
Answer:
x = 17
Step-by-step explanation:
If you subsitute x in "2x" you get 34. If you subsitute x for "4x - 4" you get 64.
After subtracting 180 from 98 you get 82. Add up 34, 64, and 82 then you get 180.

UT is the midsection of triangle QRP. If UT= x+9 and QP=4x-27, what is the length of QP?
Answer:
Step-by-step explanation:
4x - 27 = 2(x + 9)
2x = 27 + 18
x = 45 ÷ 2 = 22.5
QP = 4(22.5) - 27 = 63 units

Who climbs at a faster rate? Make sure to explain your answer and how you know
Answer:
Start at -150, then add 3(-5), then add 122.2. -150 + 3(-5) + 122.2 = -45.3.
The answer is -45.3 feet depth. while minus sign shows the descend under the water with water surface as starting point.
Step-by-step explanation:
Initial depth of diver under the water =-150feet=−150feet
Diver descends 5 feet per minute for 3.5 minutes =3.5*(-5)=3.5∗(−5)
=-17.5=−17.5
Note: minus sign shows that the diver is under the water.
Diver ascends =122.2feet=122.2feet
Now adding all the terms a below as a numerical expression.
Current Depth of Diver after he descends 5 feet for 3.5 minutes and ascend 122.2 feet after =-150-17.5+122.2=−150−17.5+122.2
=45.3feet=45.3feet
By taking the initial depth of diver from which we add or subtract the changes made when he ascends or descends in the water to get the current depth.
