Statistical Questions are questions that have more than one answer. Which subjects do the students in my class like? What is the height of each student in my class? How many students from each school in the city loves football? How many servings of fruit did I eat each day this month? What is the highest temperature of each month this year?

The height of a trapezoid can be expressed as x – 4, while the bases can be expressed as x + 4 and x + 9. if the area of the tra
AlexFokin [52]

Answer: 19 cm

<u>Step-by-step explanation:</u>

A_{trapezoid}=\frac{b_{1}+b_{2}}{2}*h

                99 = \frac{(x+4 + x+9}{2}*(x - 4)

                99 = \frac{(2x + 13}{2}*(x - 4)

              198 = (2x + 13)(x - 4)

              198 = 2x² + 5x - 52

                 0 = 2x² + 5x - 250

                 0 = 2x²- 20x + 25x - 250

                 0 = 2x(x - 10) + 25( x - 10)

                 0 = (2x + 25)(x - 10)

0 = 2x + 25     or        0 = x - 10

  -\frac{25}{2} = x      or          x = 10

Since length cannot be negative, -\frac{25}{2} can be disregarded

Larger base: x + 9  = 10 + 9   = 19

Which graph matches the equation ?
gulaghasi [49]

Answer:

Pretty sure it's the first one. It's the only one with the correct y-intercept and has a positive slope.

This is in fancy form, so you want to simplify it:

y = 3/4(x+4) - 6

Multiply it all,

y = 3/4x + 3/4(4) - 6

y = 3/4x + 3 - 6

y = 3/4x - 3

The first one matches.

s344n2d4d5 [400]

The statement; Approximately 120 families turned on their televisions for less than 37 hours is true.

<h3>What is true about the data?</h3>

From the task content, since the 10% percentile of the data corresponds to 24 families, it.follws that the total number of families sampled is; 24 × 10 = 240 families.

On this note, after the first 120 data points, the median is determined to be 33.2 hours which is less than the mean. Conclusively, it follows that approximately 120 families turned on their televisions for less than 37 hours.

Hence, the statement is true.
