Solve for x on each of these questions please!
IgorLugansk [536]

Answer:

1. x = 10

2. x = 4

Step-by-step explanation:

I use the angle ABC method:

AB² + AC² = BC²

6² + 8² = x²

x = 10

AB² + AC² = BC²

3² + x² = 5²

x = 4

Solve for a. 1/3(21-3a)=6-a
OverLord2011 [107]

Answer:

no solution

Step-by-step explanation:

Given

\frac{1}{3} (21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )

21 - 3a = 18 - 3a ( subtract 21 from both sides )

- 3a = - 3 - 3a ( add 3a to both sides )

0 = - 3 ← not possible

This indicates the equation has no solution

If the average weight for cats is 12
Mariulka [41]

Answer:

3 standard deviations

from the mean is 6 pounds to 18 pounds.

Step-by-step explanation:

The above question is solved using empirical rule

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ

From the above question

μ = 12 pounds

σ = 2 pounds

Hence:.

3 standard deviations from the mean is calculated as

μ - 3σ

[12 - 3(2)] pounds

=( 12 - 6) pounds

= 6 pounds

μ + 3σ

[12 + 3(2)] pounds

=( 12 + 6) pounds

= 18 pounds

Hence,3 standard deviations

from the mean is 6 pounds to 18 pounds.
