Step-by-step explanation:

<u><em>I think your full question is below: </em></u>

<em>A store asked 250 of its customers whether they were satisfied with the service or not. The responses were also classified according to the gender of the customers. We want to study whether there is a relationship between satisfaction and gender. </em>

<em>A meaningful display of the data from this study would be: </em>

<em>(a) side-by-side boxplots </em>

<em>(b) a pie chart </em>

<em>(c) a histogram </em>

<em>(d) a scatterplot </em>

<em>(e) a two-way table</em>

Explain:  two-way frequency table will deal with two variables, between two sets of categorical data. With genders we have two types: man and female, so two - way table are the best option to display your data.

7. Eduardo has $150 in savings and makes $9.75 per hour. Jennifer has $90 in savings and earns $15.25 for each
Stells [14]

Answer:

  a) 150-90 = h(15.25 -9.75)

  b) 10.91

Step-by-step explanation:

a) Jennifer has 150 -90 = 60 less in savings than Eduardo, but she is earning 15.25 -9.75 = 5.50 more per hour. An equation she can use to figure her hours is ...

  60 = 5.50h . . . . for h hours worked.

In 'raw' form, that might be ...

  150 -90 = (15.25 -9.75)h

__

b) Solving the above equation, we get ...

  60/5.50 = h ≈ 10.90909 ≈ 10.91 . . . hours

Which function has zeros at x = -2 and x = 5?
riadik2000 [5.3K]

Answer:

<em>f(x)=x²-3x-10</em>

Step-by-step explanation:

\begin{gathered}f(x) = x {}^{2} - 3x - 10 \\ to \: find \: x \: intercept \:o r \: zero \: substitute \: f(x) = 0\: \\ 0 = x {}^{2} - 3x - 10 \\ x {}^{2} - 3x - 10 = 0 \\ x {}^{2} + 2x - 5x - 10 = 0 \\ x(x + 2) - 5x - 10 = 0 \\ x(x + 2) - 5(x + 2) = 0 \\ (x + 2).(x - 5) = 0 \\ x + 2 = 0 \\ x - 5 = 0 \\ x = - 2 \\ x = 5\end{gathered}

f(x)=x

2

−3x−10

tofindxinterceptorzerosubstitutef(x)=0

0=x

2

−3x−10

x

2

−3x−10=0

x

2

+2x−5x−10=0

x(x+2)−5x−10=0

x(x+2)−5(x+2)=0

(x+2).(x−5)=0

x+2=0

x−5=0

x=−2

x=5

therefore the zeros of the equation are x₁=-2,x₂=5
