Item 5 Identify the terms, coefficients, and constants in the expression 6 + n x n + 1/2d

Alenkasestr [34]

Answer:

Terms (Variables) = x , d . Their corresponding coefficients = n^2 , 1/2 . Constant = 6

Step-by-step explanation:

6 + n x n + 1/2d

6 + n^2 x + 1/2d

Terms (Variables) = x , d . Their corresponding coefficients = n^2 , 1/2 . Constant = 6

If A = C + 3A=C+3, B = 2CB=2C, and C = 4C=4, which is the correct order from least to greatest?

kotykmax [81]

Answer:

B, C, A.

Step-by-step explanation:

A = C + 3A = C + 3

A = C + 3

A = C + 3A

C + 3A = C + 3

3A = 3

A = 1

A = C + 3

1 = C + 3

C + 3 = 1

C = -2

B = 2C

B = 2(-2)

B = -4.

So, from least to greatest, B = -4, C = -2, and A = 1.

Hope this helps!

The quotient rule for exponents states that bm bn=_______, b≠0 . When dividing exponential expressions with the same nonzero b

wariber [46]

Answer:

The quotient rule for exponents states that $b^{m}\div b^{n}=b^{m-n}$ .

When dividing exponential expressions with the same nonzero base, <u>subtract</u> the exponents.

Step-by-step explanation:

Some rules to solve exponents are:

$x^{0}=1$
$(x^{m})^{n}=x^{mn}$
$x^{-n}=\frac{1}{x^{n}}$
$x^{m}\cdot x^{n}=x^{m+n}$
$\frac{x^{m}}{x^{n}}=x^{m-n}$

The quotient rule for exponents states that:

$b^{m}\div b^{n}=b^{m-n}$ .

When dividing exponential expressions with the same nonzero base, <u>subtract</u> the exponents.

A consumer advocate wants to collect a sample of jelly jars and measure the actual weight of the product in the container. He ne

Ivahew [28]

Answer:

n=3.8416≅4

So Minimum Sample Size is 4

Step-by-step explanation:

In order to find the minimum sample size, the formula we use will be:

$n= \frac{Z^2*S^2}{E^2}$

Where:

n is sample size

Z is the distribution

S is the standard deviation

E is the Margin of error

S=3 ,E=3

For Z:

Alpha=1-0.95=0.05

Alpha/2=0.025=2.5%

From Cumulative Standard Distribution Table:

Z at Alpha/2 = 1.960

$n= \frac{1.960^2*3^2}{3^2}$

n=3.8416≅4

So Minimum Sample Size is 4

An office building loses a third of its heat between sundown and midnight and an additional half of the original amount of heat

Mekhanik [1.2K]

Answer:

$\dfrac{1}{16}$

Step-by-step explanation:

Proportion of Heat Loss Between sundown and midnight $=\dfrac{1}{3}$

Proportion of Heat Loss between midnight and 4 AM $=\dfrac{1}{2}$

Proportion of Total Heat Already Lost $=\dfrac{1}{3}+\dfrac{1}{2} =\dfrac{5}{6}$

Proportion of Remaining Heat $=1-\dfrac{5}{6}=\dfrac{1}{6}$

Between 4 AM and 5 AM, five-eighths of the remaining heat is lost.

Proportion of Heat Loss between 4 AM and 5 AM= $\dfrac{5}{8}$ X \dfrac{1}{6} = \dfrac{5}{48}$

Therefore, Proportion of Remaining Heat Left $=\dfrac{1}{6}- \dfrac{5}{48}=\dfrac{1}{16}$

We therefore say that:

$\dfrac{1}{16}$ of the total heat loss occurs between 5 AM and sunrise.$
