Answer:

x = 6

Step-by-step explanation:

multiply both terms in the parenthesis by the factor 4:

3 = 4(x-2) + 5 - 3x

3 = (4*x) - (4*2) + 5 - 3x

then simplify

3 = 4x - 8 + 5 - 3x

rearrange terms

3 = 4x - 3x - 8 + 5

subtract 3x from 4x: (4x - 3x = 1x, which is just x)

3 = 1x - 3

3 = x - 3

then add 3 to both sides:

6 = x

x = 6

Answer:

6 = x

Step-by-step explanation:

first, we simplify the parenthesis by distributing the 4

3 = 4(x - 2) + 5 - 3x

3 = 4x - 8 + 5 - 3x

then, you add like terms

3 = x - 3

then add 3 to both sides to isolate x

6 = x

I’m giving all the points I have, plz help and get it right? Someone please help me

Feliz [49]

Answer:

The area (probability) is: 0.6864.

Step-by-step explanation:

According to the statement, we are in front of a normal distribution with the following parameters:

µ (mean) = 0

σ (Standard deviation) = 1.

Then we need to find the area of the shaded region, which is the area between the points -1.21 < z < 0.84.

And the area (probability) is: 0.6864.

let <ACB=<C,

Here h=26 due to opposite to right angle is hypotenuse and b=10 Is a base and p=24 due to opposite to the angle <C

so,

Cos<C=b/h

=10/26

=5/13

Sample size: A researcher is trying to decide how many people to survey. Which of the following sample sizes will result in a co

oksian1 [2.3K]

Answer:

Step-by-step explanation:

Given that a researcher is trying to decide how many people to survey.

We have confidence intervals are intervals with middle value as the mean and on either side margin of error.

Confidence interval = Mean ± Margin of error

Thus confidence interval width depends on margin of error.

Margin of error = $Critical value *\frac{\sigma}{\sqrt{n} }$

Thus for the same confidence level and std deviation we find margin of error is inversely proportional to square root of sample size.

Hence for small n we get wide intervals.

So if sample size = 300, the researcher will get wider confidence interval

Jackie has $32.50 to buy a new pair of jeans. The pair she likes costs $38 but is marked “20% off ticketed price.” The sales tax

ohaa [14]

Hello! So, the jeans are 20% off of the original price. While she gets 20% off of the jeans, she still has to pay 80% of the price. To find out the discount price, multiply 38 by 80% (0.8). 38 * 0.8 is 30.4 $30.40 is the discount price. There is 5% tax on the item. First off, let's add 1 to the rate. 5% is 0.05 in decimal form. 1 + 0.05 is 1.05. We add 1 to the percentage rate, because adding that and multiplying that amount will bring us straight to the new price. Now, multiply 30.4 and 1.05 together to get the new price. When you do, you get 31.92. $31.92 is the price of the jeans. 31.92 < 32.50. Jackie has enough money to buy the jeans.
