Answer:

no

Step-by-step explanation:

To determine if x = 7 is a solution.

Substitute x = 7 into the equation and if left side equals right side then it is a solution

3(7) - 4 = 21 - 4 = 17 ≠ 15

Then x = 7 is not a solution to the equation

What is the least common denominator of 7/10 and 4/9
melisa1 [442]

Answer:

7/10 = 63/90

4/9 = 40/90

Step-by-step explanation:

Rewriting input as fractions if necessary:

7/10, 4/9

For the denominators (10, 9) the least common multiple (LCM) is 90.

LCM(10, 9)

Therefore, the least common denominator (LCD) is 90.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

7/10 = 7/10 × 9/9 = 63/90

4/9 = 4/9 × 10/10 = 40/90

Svetlanka [38]

Answer: (22.41, 25.59)

Step-by-step explanation:

The t-critical value with 17 degrees of freedom for a 95% confidence interval is : 2.11

Sample mean = 24

Standard deviation = 3.2

Standard error of mean = s / √ n

Standard error of mean = 3.2 / √ 18

SE = 3.2/4.2426

Standard error of mean 0.7542

Confidence interval 24-(0.7542)(2.11) = 22.41 and

24+(0.7542)(2.11) =25.59

How do exponets allow u to communicate more Prescisey to others
Vikentia [17]
Exponents allow for shorter, more concise answers. Say you needed to state the number 88,209. 9^5 is a much shorter number, and still gets the point across.
