olga2289 [7]

Answer:

(96.91, 101.09)

Step-by-step explanation:

To calculate the interval, you require the Z value at 95% confidence interval. The Z value is 1.96. The formula to calculate the confidence interval:

$X-Zs/\sqrt{x} \\X+Zs/\sqrt{x}$

Where X is the mean and s is the standard deviation and x the sample size:

$99-1.96\cdot{5}/\sqrt{22} \\99+1.96\cdot{5}/\sqrt{22}$

The interval is (96.91, 101.09)

3. -x + 2 < 3x - 6

=3x +x < 2 + 6

=4x < 8

=x > 8/4

=x > 2

4. 3v - 12 > 5v + 10

= 5v-3v > 10+12

=2v > 22

= v < 22/2

=v < 11
