Pine bluff middle school is having its annual spring fling dance, which will cost $400\$400$400dollar sign, 400. the student treasurer reported that the dance fund has $75\$75$75dollar sign, 75 left over from last year. each ticket to the dance costs $4\$4$4dollar sign, 4.

let t represent the number of tickets sold. write an inequality to determine how many tickets must be sold to pay for this year's dance.

Use this data in the problem below. follow the steps carefully. round to the nearest tenth. lot 3: week 1: 345 week 2: 340 week 3: 400 week 4: 325 step 1. jim enters the data and calculates the average or mean. step 2. jim calculates the deviation from the mean by subtracting the mean from each value. step 3. jim squares each deviation to remove negative signs. step 4. jim sums the squares of each deviation and divides by the count for the variance. step 5. jim takes the square root of the variance to find the standard deviation.

Find the indicated value, where g(t) = t^2-t and f(x)= 1+x a. -2 b. 0 c. 2 d. 8

Kylie explained that (-4x+9)^2 will result in a difference of squares because (-4x+9)^2 (-4x+9)^2 =(-4x)^2+(9)^2=16x^2+81
