Answer:

Simplifying

4cos(10x) + 2 = 2

Remove parenthesis around (10x)

4cos * 10x + 2 = 2

Reorder the terms for easier multiplication:

4 * 10cos * x + 2 = 2

Multiply 4 * 10

40cos * x + 2 = 2

Multiply cos * x

40cosx + 2 = 2

Reorder the terms:

2 + 40cosx = 2

Add '-2' to each side of the equation.

2 + -2 + 40cosx = 2 + -2

Combine like terms: 2 + -2 = 0

0 + 40cosx = 2 + -2

40cosx = 2 + -2

Combine like terms: 2 + -2 = 0

40cosx = 0

Solving

40cosx = 0

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Divide each side by '40'.

cosx = 0.0

Simplifying

cosx = 0.0

The solution to this equation could not be determined.

Step-by-step explanation:

GREYUIT [131]
Base pay = $11 x 40 or $440

$605 - 440 = $165 in overtime
Overtime is 1.5 (1 and a half times) her usual salary

11 x 1.5 = $16.50

$165 ÷ $16.50 = 10 hours of overtime.

The alpha level that a researcher sets at the beginning of the experiment is the level to which he wishes to limit the probabili
Lelu [443]

Answer:

Kindly check explanation

Step-by-step explanation:

The alpha level set at the beginning of of an experiment is used by the researcher to the limit the probability if making a type 1 error. The type 1 error is committed when a true null hypothesis is incorrectly rejected.

The type 2 error on the other hand is committed when fail to reject a false null hypothesis.

Hence, in other to forestall the risk of incorrectly rejecting a true null hypothesis, the alpha level is set.

When critical region is split across both tails of the distribution, The z-score boundaries at an alpha level α = .05

α = .05 (95% confidence level)

When region is split into 2:

α/2 = .05/2

α/2 = 0.025

Loooking up the z table for the Zscore with probability of 0.025

Zscore = ±1.96

What is the value of 3 in 8,531,980,112.45
Neko [114]

Answer:

30,000,000

Step-by-step explanation:

You are given the number 8,531,980,112.45.

Look at attached place value chart.

If we go to the left from decimal point, then we have

  • ones;
  • tens;
  • hundreds;
  • thousands;
  • ten thousands;
  • hundred thousands;
  • millions;
  • ten millions;
  • and so on.

Digit 3 in the number  8,5 <u>3</u> 1,980,112.45 is on ten millions position, so the value of this digit is 30,000,000

Write a power that has a value greater than 340 and less 345
valina [46]

For this case we must write a power between (340,345)

We chose 343.

We divide the number until we get an exact division:

\frac {343} {2} = 171.5\\\frac {343} {3} = 114.3\\\frac {343} {4} = 85.75\\\frac {343} {5} = 68.6\\\frac {343} {6} = 57.17\\\frac {343} {7} = 49\\

So we have:

7 ^ n = 343\\n = 3

So, the power is:

7 ^ 3 = 7 * 7 * 7 = 49 * 3 = 343

ANswer:

7 ^ 3 = 7 * 7 * 7 = 49 * 3 = 343
