Answer:
300/1 or 300
Step-by-step explanation:
I took the quiz
The product of the given numbers is 29,89,854.
The given expression is [(−427⋅(−18))⋅((−389)⋅(−1))].
What is product of integers?Integers are the set of whole numbers and their opposites. When you multiply integers, the numbers that you are multiplying are called factors. Your answer after multiplying is called a product.
Product of negative and negative integers is positive.
Now,
(−427⋅(−18)) = 7686
((−389)⋅(−1)) = 389
7686 × 389 = 29,89,854
Therefore, the product of the given numbers is 29,89,854.

Answer:
-3x^2-10x+6
Step-by-step explanation:
the first mistake would be writing the 4x^2 as positive when it's supposed to be negative. the 1 is also supposed to be positive. correct difference would be:
(x^2-10x+5)-(4x^2-1)
=(x^2-4x^2)-10x+5+1
=-3x^2-10x+6
Answer:
Mistake in step 2
Step-by-step explanation:
(x^2-10x+5)-(4x^2-1)
x^2-10x+5-4x^2+1
-3x^2-10x+6
-(3 x^2 + 10 x - 6)

Trey is taking his friends out to dinner to celebrate graduation. It will cost him $72 to reserve a table, and another $5 per guest. How many people can he invite if he can only spend up to $130?
Answer:
11 people
Step-by-step explanation:
first, youd subtract the table reservation price from the max price.
130 - 72 = 58
then, since each person costs $5, you find the highest multiple of 5.
in this case, its 55, which has 11 groups of 5 in it.
to make sure:
you can then subtract 55 from 58 to make sure there isnt any extra 5's.
58 - 55 = 3.

Answer:

Step-by-step explanation:
The number of termites in a nest in any given month can be represented by the
function f(t) = 4(3)^t where t represents the number of months.
The number of ants in a box can be represented by the function represented by the
table:
Months
0-1-2-3-4
Number 20-45-101-228-513
What is the positive difference in the number of termites and the number of ants in
the fourth year?
im pretty sure the answer is 189
The positive difference in the number of termites and the number of ants in the fourth month will be 189. Option B is correct.
What is the application of subtraction?In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.
It is given that, the number of termites in a nest in any given month can be represented by the function [tex]\rm f(t) = 4(3)^t[/tex].
For the fourth month,
f(4) = 4(3)⁴
f(4) = 324
From the table, it is observed that the number of ants in four months is 513.
The positive difference in the number of termites and the number of ants in the fourth month is found as,
=513-324
=189
Thus, the positive difference in the number of termites and the number of ants in the fourth will be 189. Option B is correct.

For the standard normal distribution, the area between z = 0 and z = 1.70, rounded to four decimal places, is:
Using normal distribution table, the area between z=0 and z=1.70 is the difference between p(z=0) and p(z=1.70). Hence, the area between z=0 and z = 1.70 is 0.4554
Using a normal distribution table :
P(Z < 0) = 0.5 P(Z < 1.70) = 0.95543The Area between z=0 and z= 1.70 is defined as the difference between the probabilities of (z < 1.70) and (z < 0)
P(Z < 1.70) - P(Z < 0) = 0.95543 - 0.5 = 0.45543
Therefore, the area between z = 0 and z = 1.70 rounded to four decimal places is 0.4554
