8x - 3 = 5 (2x + 1) solve for x

-4

Step-by-step explanation:

Given:

• 8x - 3 = 5 (2x + 1)

Solving for x:

• 8x - 3 = 10x + 5
• 10x - 8x = -3 - 5
• 2x = - 8
• x = -8/2
• x = -4

x=−4

A random sample of size 100 was taken from a population. A 94% confidence interval to estimate the mean of the population was computed based on the sample data. The confidence interval for the mean is: (107.62,129.75). What is the z-value that was used in the computation. Round your z-value to 2 decimal places.

Step-by-step explanation:

The confidence interval for population mean is given by :-

Given : Significance level :

Critical value :

By using the standard normal distribution table for z, we find the critical value of corresponds to the p-value 0.03.

Hence, the z-value that was used in the computation must be 1.88 .

1. An equation is shown below.3 (x-2) + 7x= 1/2(6x-2)
How many solutions, if any, does the equation have?

x=5/7

Step-by-step explanation:

3(x-2)+7×=1/2×(6×-2)

3x-6+7×=1/2×2(3×-1)

3×-6+7×=3×-1

-6+7×=-1

7×=-1+6

7×=5

In ΔBCD, the measure of ∠D=90°, CB = 25, BD = 7, and DC = 24. What is the value of the sine of ∠C to the nearest hundredth?

Answer: The value of the sine of ∠C is 0.28.

Let's draw a triangle again (see the picture below).

Remember SOHCAHTOA? It's:

-sin = opposite/hypotenuse

We need to use sin in here.

The sin of C is , which in a calculator, gives

How would you write the number displayed on the calculator screen in standard form

E is short for 10^x. The number that comes after the E is the power of 10.

So its 7.6*10^12

now that scientifically notation

For standard your gonna need to simplify that

so we know 10^12 is 1000000000000

Multiply the 7.6

7600000000000

hope I helped :)
