4.  Solve

1430 = 0.55t^2 + 550

1430 - 550 =880 = 0.55t^2

880/0.55 = 1600 = t^2

t= \pm \sqrt{1600} = \pm 40

On the positive answer makes sense.

Answer: Month 40

5. The throw ends when the height is zero (I guess we're ignoring rolling).

0 = -0.02x^2 + x + 6

x = \dfrac{-1 \pm \sqrt{1^2 - 4(6)(-0.02)}}{2(-0.02)}

Only the negative sign for the plus/minus will give a sensible, positive answer:

x = \dfrac{-1 - \sqrt{1^2 - 4(6)(-0.02)}}{2(-0.02)} = 55.4138

Answer: 55.4 feet

Answer:

Each term is separated by an addition or subtraction sign.

Coefficients are numbers in front of a variable (letter).

Constants are numbers with nothing else.

so you get

2  |  2  |  3              |  1

6  |  6  |  0.2, -1, 8  |   1/2

3  |  -3 |   -              |  -

Answer:

No, Mr. Hernandez’s sample is random, not biased, large enough compared to the population, but 28 is not 20% of 90.

Step-by-step explanation:

At Lawson Middle School, Mr. Hernandez asked 90 randomly selected students from each grade level for their favorite subject.

   90 randomly selected students from each grade level for their favorite subject, and 28 chose social studies as their favorite.

so, the percent of students who love social studies is given by:

28/90 x 100=31.11%

   He used this data to draw the inference that out of the 250 middle school students, about 20% prefer social studies.

No, Mr. Hernandez’s sample is random, not biased, large enough compared to the population, but 28 is not 20% of 90.
