What is the degree measure of

Jared is constructing a circle graph to

Natasha_Volkova [10]

Answer:

1.8

Step-by-step explanation:

because since its 30 students and 6 of those chose basketball.

So u divide 30 from 6

= 1.8%

So Jared shaded 1.8% of the 6 students that chose basketball.

Determine the slope between the points (-1, -5) and (5, 4)

Basile [38]

Answer:

Slope = 9/6

Step-by-step explanation:

Step 1: We have formula to find the slope if we are given two point.

<h3>slope = $\frac{(y2 - y1)}{(x2 - x1)}$ </h3>

Given points (-1, -5) and (5, 4)

Here x1 = -1, y1 = -5 and x2=5 and y2 = 4

Step 2: Plug in those values into formula and simplify.

Slope = (4 - (-5)) / (5 - (-1))

= (4 + 5)/(5 + 1) -(-5)= 5 and -(-1) = 1

Slope (m) = 9/6

Thank you.

Hope you will understand this.

how many fewer rainy days are there than sunny and cloudy days when there are 6 sunny days, 4 cloudy days and 7 rainy days

Cloud [144]

3 more fewer days because 6+4=10 and 10-7=3.

Hope that helped:)

On a coordinate plane, a parabola opens to the left. It has a vertex at (0, 0), a focus at (negative 2, 0), and a directrix at x

Musya8 [376]

The equation represents the parabola shown on the graph is x^2 = - 8y . Option D

<h3>How to determine the equation</h3>

We were given the following parameters;

Vertex ( 0, 0 )
Focus ( -2, 0)
Directrix , at x = 2

The standard for a parabola is given as;

y² = 4ax

It can also be written as;

x² = 4ay

Given the focus as ( -2, 0), we have the value of 'a' to be -2

Now, let's substitute the value into the standard equation of a parabola

x^2 = 4ay

x^2= 4 × -2 × y

Multiply through

x^2 = - 8y

The equation of the parabola is x^2 = - 8y

Thus, the equation represents the parabola shown on the graph is x^2 = - 8y . Option D

The partners at an investment firm want to know which of their two star financial planners, Brayden or Zoe, produced a higher me

Zigmanuir [339]

Answer:

Correct options are (B) and (C).

Step-by-step explanation:

A two-sample t-test can be used to determine which of the two star financial planners, Brayden or Zoe, produced a higher mean rate of return last quarter for their clients.

The hypothesis is defined as:

H₀: The population mean rate of return for Brayden is same as that for Zoe, i.e. μ₁ - μ₂ = 0.

Hₐ: The population mean rate of return for Brayden is less than that for Zoe, i.e. μ₁ - μ₂ < 0.

The significance level of the test is, α = 0.05.

The decision rule is:

If the p-value of the test is less than the significance level of 5% then the null hypothesis is rejected.

And if the p-value of the test is more than the significance level of 5% then the null hypothesis is failed to be rejected.

The p-value of the test is computed to:

p-value > 0.10

If the p-value is greater than 0.10 then it is definitely greater than 0.05.

So, p-value > α = 0.05.

The null hypothesis will not be rejected at 5% level of significance.

Conclusion:

The conclusion of the hypothesis tests is that there is sufficient evidence to suggest that the population mean rate of return for Zoe is greater than the population mean rate of return for Brayden.

Thus, the correct options are (B) and (C).
