D = (12) / (3)(4). Substitute the values of a, b, and c into the equation.
D = 4 * (4) : Use DMAS from left to right. Remember that DMAS means "from left to right, division *and* multiplication and then addition *and* subtraction," rather than "from left to right, division, *then* multiplication, *then* addition, *then* subtraction." It's an important difference.
D = 16

D= (12)/(3)(4)
d = 12/12
d = 1

Which expression is the additive inverse of n?<br> A. 1/n<br> B. -n<br> C. -1/n<br> D. -(-n)

Marrrta [24]

The additive inverse of something is whats added to the original to get 0

So in this case n - n = 0, which is B :)

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 436.0 gram setting. It

Vilka [71]

Answer:

We conclude that the machine is under filling the bags.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 436.0 gram

Sample mean, $\bar{x}$ = 429.0 grams

Sample size, n = 40

Alpha, α = 0.05

Population standard deviation, σ = 23.0 grams

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 436.0\text{ grams}\\H_A: \mu < 436.0\text{ grams}$

We use one-tailed(left) z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{429 - 436}{\frac{23}{\sqrt{40}} } = -1.92$

Now, $z_{critical} \text{ at 0.05 level of significance } = -1.64$

Since,

$z_{stat} < z_{critical}$

We reject the null hypothesis and accept the alternate hypothesis. Thus, we conclude that the machine is under filling the bags.

PLS ANSWER QUICK I WILL GIVE BRAINLIEST

NISA [10]

Answer:

B

Step-by-step explanation:

First, we are decreasing the number so it has to be a decrease.

Next, we divide 7/31 and get around 0.23, which also represents 23 percent.

This only shows that 7 is 23 percent of 31, so we need to find the decrease by seeing the difference of 100 and 23.

We get 100 - 23 = 77, and because it is a decrease we get B.
