Diego and Jada are both trying to write an expression with fewer terms that is equivalent to
7a + 5b - 3a + 4b
Jada thinks 10a - 1b is equivalent Diego thinks 4a + 9b is equivalent
Answer: Diego, 4a + 9b is equivalent
Step-by-step explanation:
7a + 5b - 3a + 4b
= (7a - 3a) + (5b + 4b) We rerange the variables, and put them together with (), which make it more clear to solve.
= 4a + 9b
The population density of City A is 6000 people per square mile. City B is a dilation of City A with scale factor 1.5 . If City B has 3/5 of the population of City A, what is the population density of City B?
Answer:
[tex]1600\ \text{people per square mile}[/tex]
Step-by-step explanation:
Number of people per square mile in City A is 6000.
In terms of size City B is a dilation of City A with scale factor 1.5.
This means a length of 1 mile in city A would be 1.5 miles in city B.
So, [tex]1\ \text{mile}^2\text{ in City A}=1.5^2\ \text{mile}^2\text{ in City B}[/tex]
City B has [tex]\dfrac{3}{5}[/tex] of the population of City A.
So the population density of City B would be
[tex]\dfrac{\dfrac{3}{5}\times 6000}{1.5^2}=1600\ \text{people per square mile}[/tex]
The population density of City B is [tex]1600\ \text{people per square mile}[/tex].

Brooke bought 5 plates for $44. If the price of the plates is always the same, which represents the total cost, y, of buying any number of plates, x?
Answer:
y = 8.80x
Step-by-step explanation:
Th price of one plate = $44 / 5 = $8.80
the cost of any x plate can be determined by multiplying $8.80 by x
y = $8.80x
For example if x is 10, y = $8.80(10) = $88
If x = 100, y = $8.80(100) = $880
Answer:
y = 8.80x
Step-by-step explanation:
Th price of one plate = $44 / 5 = $8.80
the cost of any x plate can be determined by multiplying $8.80 by x
y = $8.80x
For example if x is 10, y = $8.80(10) = $88
If x = 100, y = $8.80(100) = $880

Which point is coplanar with a, b and c in the diagram below
Answer:
D because it on the same plane as abc so it is a coplanar. also I got it right on my test.
Point D is coplanar with A, B, and C because it is on the same plane as A, B, and C option (4) is correct.
What is a rectangular prism?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape. It is also called a cuboid.
It is given that:
A rectangular prism is given,
Geometry can be defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.
As we know in the rectangular prism there are eight vertices and six faces.
From the figure, we can see clearly that point D is coplanar with A, B, and C.
Point D is coplanar with A, B, and, C.
Thus, point D is coplanar with A, B, and C because it is on the same plane as A, B, and C option (4) is correct.

While running a 2-sample z-test for two proportions, you find a test statistic of z=1.946. If the test is two-tailed and α=0.05, what decision will you make?
Answer:
Decision is to fail to reject the null hypothesis.
Step-by-step explanation:
Since our significance level is α = 0.05, but since it's a two tailed test for two proportions, in each tail, we will have 0.05/2 = 0.025.
Now, the rejection region will be the critical value at 1 - 0.025 = 0.975
From the z-table attached, the critical value at 0.975 is 1.96.
Thus, our decision rule will be;
If Z-score is less than -1.96, or greater than 1.96, we will reject the null hypothesis.
Now, we have a z-score of z = 1.946 in the question. This lies between -1.96 and 1.96.
Thus,we will fail to reject the null hypothesis

An urn contains 5 red marbles 9 white and 7 blue marbles marbles.A child randomly selects three (without replacement) from the urn.Round to four decimal place.Find the probability all marbles are the same.
Answer:
0.0970
Step-by-step explanation:
Red marbles, R= 5
White, W = 9
Blue, B = 7
Total = (5 + 9 + 7) = 21
Selecting 3 marbles without replacement :
Probability that all marbles are the same
P(RRR) or P(BBB) or P(WWW)
(5/21 * 4/20 * 3/19) + (7/21 * 6/20 * 5/19) + (9/21 * 8/20 * 7/19)
0.0075187 + 0.0263157 + 0.0631578
= 0.0969922
= 0.0970

The bank contains pennies, nickels, dimes, and quarters. There are 4 more nickels than pennies. How much money does the bank contain
Of the 50 coins 10% are pennies and 42% are dimes
The amount of money in the bank contains 5 pennies, 9 nickels, 21 dimes, and 15 quarters.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown.
First, let's find the number of pennies in the bank.
Since 10% of the coins are pennies, and there is 50 coins total, the number of pennies is :
10/100 × 50 = 5
Now let's find the number of dimes. Since 42% of the coins are dimes, and there is 50 coins total, the number of dimes is :
42/100 × 50 = 21
Since there are 4 more nickels than pennies, the number of nickels is :
5 + 4 = 9
Finally, the number of quarters is: 50 - 5 - 9 - 21 = 15
Thus, the bank contains 5 pennies, 9 nickels, 21 dimes, and 15 quarters.
