So you’ll add 3w+5w=8w then multiply the 2 on both side so you cancel the division so 2* 8w/2 -6 =18*2 so youll be left with 8w-6= 36 now youll add 6 to both sides to cancle the subtraction so 8w-6+6=36+6 which will get you to 8w=42 so now you divide the 8 from each side 8w/8=42/8 which will give you the answer which is w= 5.25

Answer:

w=6

Step-by-step explanation:

First, we want to isolate the variable.

Add 6 on both sides

$\frac{3w+5w}{2} =24$

Multiply both sides by 2.

3w+5w=48

Combine like terms.

8w=48

Divide both sides by 8.

w=6

I hope this helps!

Is 0.04 greater than 0.4

No
0.04 is actually smaller than 0.4 because the four is in the hundredths place which is smaller than the four in the tenths place of 0.4

The product of (a − b)(a − b) is a2 − b2.<br> A. Sometimes<br> B. Always<br> C. Never

Damm [24]

$(a-b)(a-b)=a^2-2ab+b^2\\\\a^2-2ab+b^2=a^2-b^2\\2b^2=2ab\\b^2=ab\implies a=b \vee b=0$

So, sometimes.

When Carson runs the 400 meter dash, his finishing times are normally distributed with a mean of 65 seconds and a standard devia

just olya [345]

Given Information:

Mean time to finish 400 meter dash = μ = 65 seconds

Standard deviation to finish 400 meter dash = σ = 2.5 seconds

Confidence level = 95%

Required Information:

95% confidence interval = ?

Answer:

$CI = 60 \: to \: 70 \: seconds$

Step-by-step explanation:

In the normal distribution, the empirical rule states approximately 68% of all the data lie within 1 standard deviation from the mean, approximately 95% of all the data lie within 2 standard deviations from the mean and approximately 99.7% of all the data lie within 3 standard deviations from the mean.

The confidence interval for 95% confidence limit is given by

$CI = \mu \pm 2\sigma$

Since approximately 95% of all the data lie within 2 standard deviations from the mean. μ is the mean time Carson takes to finish 400 meter dash and σ is the standard deviation.

$CI = 65 \pm 2(2.5)$
