Answer:
x>14
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
-4>-2x+24
Step 2: Flip the equation.
-2x+24<-4
Step 3: Subtract 24 from both sides.
-2x+24-24<-4-24
-2x<-28
Step 4: Divide both sides by -2.
-2x-2<-28-2
x>14

Answer:
12083.929
Step-by-step explanation:
First step: find the mean of the data.
mean = <u>3</u><u>+</u><u>3</u><u>3</u><u>+</u><u>3</u><u>0</u><u>3</u><u>+</u><u>2</u><u>3</u><u>3</u><u>+</u><u>3</u><u>+</u><u>7</u><u>3</u><u>+</u><u>8</u><u>3</u><u>+</u><u>6</u><u>3</u>
8
= <u>7</u><u>9</u><u>4</u>
8
= 99.25
Second step: Now we calculate each dog's difference from the Mean.
Example : 3–99.25=96.25
Answer: (-96.25)+(-66.25)+203.75+133.75+(-96.25)+(-26.25)+(-16.25)+(36.25)
Third step: To calculate the Variance, take each difference, square it, and then average the result.
s² = <u>(-96.25)</u><u>²</u><u>+(-66.25)</u><u>²</u><u>+203.75</u><u>²</u><u>+133.75</u><u>²</u><u>+(-96.25)</u><u>²</u><u>+(-26.25)</u><u>²</u><u>+(-16.25)</u><u>²</u><u>+(36.25)</u><u>²</u>

Answer:
1/3
Step-by-step explanation:
The attachment shows a table with the given information filled in. Since we know 53 chose football and 23 chose tennis, the remaining 38 must have chosen running.
Then 38 out of 114 students chose running. The probability that one of those is picked at random is ...
p(running) = 38/114 = 1/3
