What is the mode of the data set?

Mathematics
1 answer:

Answer: 92 which is choice D

Look at the right side of values for the digit that comes up the most. In this case, it would be '2' in the second row. It shows up 3 times. Those leafs pair up with the stem of 9 to form the full value 92. So we have 92 show up three times which is the most frequent value.

The data set would expand out to

85, 88

92, 92, 92, 98

105, 106, 106, 109

113

126, 127

Which is the solution to the equation 8.25 + one-fourth w = 10.75? Round to the nearest hundredth if necessary.
bearhunter [10]

Answer:

w=10

Step-by-step explanation:

8.25+1/4w=10.75

8.25+0.25w=10.75

0.25w=10.75-8.25

0.25w=2.5

w=10

I hope this helps

Please help me . I need help with this. I’m getting very very frustrated !!! You can get 35 points !

Notes:

  • The sign of the coefficient of the quadratic equation determines if the vertex is a minimum or maximum.  Positive looks like ∪ so has a minimum.  Negative looks like ∩ so has a maximum.
  • Maximum/minimum height is the y-value of the vertex.
  • Time to reach maximum height is the x-value of the vertex (which is also the Axis-Of-Symmetry).

Answer:  4) maximum

               5) 20.1 ft

               6) 2 seconds

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

4) h(t) = -16t² + 256t

            ↓

            the coefficient is negative so it looks like ∩.  

            Therefore, it has a maximum.

5) h(t) = -16t² + 30t + 6

\text{AOS: }x=\dfrac{-b}{2a}\quad \rightarrow \quad x=\dfrac{-(30)}{2(-16)}=\dfrac{-30}{-32}=\dfrac{15}{16}\\\\\\\text{Maximum: }h\bigg(\dfrac{15}{16}\bigg)=-16\bigg(\dfrac{15}{16}\bigg)^2+30\bigg(\dfrac{15}{16}\bigg)+6\\\\\\.\qquad \qquad \qquad \qquad =\dfrac{-225}{16}+\dfrac{450}{16}+\dfrac{96}{16}\\\\\\.\qquad \qquad \qquad \qquad =\dfrac{321}{16}\\\\\\.\qquad \qquad \qquad \qquad \approx20.1

6) h(t)=-16t²+64t+80

\text{AOS: }x=\dfrac{-b}{2a}\quad \rightarrow \quad x=\dfrac{-(64)}{2(-16)}=\dfrac{-64}{-32}=2

5 1/3 + (-3 9/18) Simplify. Show your work.
konstantin123 [22]

Use the equivalents ...

... 1/3 = 2/6

... 9/18 = 3/6

... 1 = 6/6

First we split the mixed numbers into integer parts and fractional parts, adding each separately.

(5 1/3) + (-3 9/18) = (5 +(-3)) +(1/3 +(-9/18))

... = 2 + (2/6 - 3/6) . . . . . . use the equivalents for 1/3 and 9/18 to have a common denominator (6)

... = 2 - 1/6 . . . . . . . . . . . . the sum of the fractional parts is negative

... = (1 + 1) - 1/6 . . . . . . . . here's how we subtract it from the integer part

... = 1 + (6/6 - 1/6)

... = 1 5/6
