James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements ar

e true? Check all that apply.When x = 2, both expressions have a value of 18. The expressions are only equivalent for x = 4 and x = 6. The expressions are only equivalent when evaluated with even values. The expressions have equivalent values for any value of x. The expressions should have been evaluated with one odd value and one even value. When x = 0, the first expression has a value of 4 and the second expression has a value of 5. The expressions have equivalent values if x = 8.

find the value of n in each equation. write what n represents in the related division problem 643=4×160+n
schepotkina [342]

Answer: n = 3; n represents a remainder in a division problem.


Explanation:


1) Finding n:


i) Given: 643 = 4 × 160 + n

ii) Do the operations: 643 = 640 + n

iii) Subraction property of the equality: 643 - 640 = n

iv)  Do the operations: 3 = n

Answer: n 3


2) Meaning of n


When you divide 643 by 4 the quotient is 160 and the remainder is 3, because 160 × 4 = 640, and 643 - 640 = 3.


This is, 3 is what is left when you split 643 into 4 getting 160 whole parts (plus the remainder, 3).

Wasserman (1989) studied a process for the manufacturing of steel bolts. Historically, these bolts have a mean thickness of 10.0
zalisa [80]

Answer:

The mean of of the sample mean of these quality checks is 10 and the standard deviation is 0.7155.

Step-by-step explanation:

To solve this question, we use the central limit theorem.

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}

In this problem, we have that:

\mu = 10, \sigma = 1.6, n = 5, s = \frac{1.6}{\sqrt{5}} = 0.7155

The mean of of the sample mean of these quality checks is 10 and the standard deviation is 0.7155.

You can use substitution or elimination method to solve.  <em>I used substitution.</em>

2(1/2y + 5) + 3y = -14

y + 10 + 3y = -14

4y + 10 = -14

4y = -24

y = -6

x = 1/2y + 5  = 1/2(-6) + 5   = -3 + 5  = 2

x = 2, y = -6

Answer: A
