Answer 1

The two angles with y in them need to add up to 180 degrees

10y + 3y + 11 = 180

Simplify:

13Y + 11 = 180

Subtract 11 from both sides

13y = 169

Divide both sides by 13

Y = 13

Now solve for those two angles:

10y = 10(13) = 130

3y + 11 = 3(13) + 11 = 50

The other two angles are the same as these.

The larger angles = 130

The smaller angles = 50

Tracy's Pie Shop recently sold 15 pies, of which 3 were blackberry pies. Considering this data, how many of the next 20 pies sold should you expect to be blackberry pies?

Answers

Answer: 4

Step-by-step explanation:

We can expect that 4 of the next 20 pies sold will be blackberry pies, based on the proportion of blackberry pies in the recent sample of 15 pies.

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

If Tracy's Pie Shop recently sold 15 pies and 3 of them were blackberry pies.

Proportion of blackberry pies = 3/15

Proportion of blackberry pies = 0.2

So, in the recent sample of 15 pies, 20% were blackberry pies.

To estimate how many of the next 20 pies sold should be blackberry pies

Let us assume that the proportion of blackberry pies in the next sample of 20 pies will be similar to the proportion in the recent sample of 15 pies.

Therefore, we can use this proportion to estimate the number of blackberry pies in the next sample of 20 pies:

Number of blackberry pies = 0.2 x 20

Number of blackberry pies = 4

Therefore, we can expect that 4 of the next 20 pies sold will be blackberry pies, based on the proportion of blackberry pies in the recent sample of 15 pies.

Answer:

a = -17

Step-by-step explanation:

To solve this, we need to get A alone:

A + -21 = -38

—- +21- +21

Remember, when you do something to one side, you need to do the same thing to the other side.

Now:

A = -17!

Answers

Answer:

Step-by-step explanation:

As two sides are equal so angles opposite to these are also equal, hence

5x-4=x+52

4x=56

X=14

Now,

R=5x-4

R=66

And,Q=x+52

Q=66(we already knew both angles are equal)

Now as sum of all angles of triangle equal 180 so,

66+66+P=180

P=48

1 and 2/3 rotations. The little gear full rotation is equal to 1/6 of the big gears rotation. So if the big gear rotates once then its equal to 6 of the small rotations the extra 4 of the 10 rotations then becomes 4/6 of the big gears rotation or if simplified further, 2/3.

A parabola can be drawn given a focus of (3, 1) and a directrix of x = -5. What can
be said about the parabola?
The parabola has a vertex at
O,

Answers

Answer:

The statements that can be made about the parabola are;

The parabola opens towards the right

The equation of the parabola is (y - 1)² = 16 × (x + 1)

The parabola has a vertex at (-1, 1)

Step-by-step explanation:

The given focus of the parabola is (3, 1)

The directrix of the parabola, x = -5

Therefore, from the location of the directrix (on the x-axis) and the location of the focus relative to the directrix towards the positive direction of the x-axis relative to the directrix, the parabola opens towards the left of the coordinate chart

The general equation of the focus = (h + p, k)

The general equation of the directrix, x = h - p

Comparing with the values of the focus and the directrix of the given parabola, we have;

(3, 1) = (h + p, k)

-5 = h - p

Therefore, we get;

k = 1

h + p = 3...(1)

h - p = -5...(2)

Adding equation (1) to equation (2) gives;

h + h + p - p = 3 + (-5)

2·h = -2

h = -2/2 = -1

h = -1

From equation (1), we get;

h + p = -1 + p = 3

∴ p = 3 + 1 = 4

p = 4

The vertex of the parabola, (h, k) = (-1, 1)

The equation of the parabola in the form (y - k)² = 4·p·(x - h) is therefore, presented as follows;

The equation of the parabola = (y - 1)² = 4 × 4 × (x - (-1))

(y - 1)² = 16 × (x - (-1))

The equation of the parabola is (y - 1)² = 16 × (x + 1).

You think (claim) that the average franchise investment information shown in
the graph above is incorrect, so you randomly select 30 franchises and
determine the necessary investment for each. The sample mean investment is
$135,000 with a standard deviation of $30,000. Is there enough evidence to
support your claim at a = 0.05?

Answers

Ok I’m not trying anything for real but it’s for a couple days I’m going

Using t-test, there isn't an enough evidence to support our claim that investment average is $135,000 at α = 0.05.

What is t - test?

The one sample t test compares the mean of your sample data to a known value (population mean in our question, i.e. , we wish to compare the sample mean with the population mean). One sample t test should be used when you the population standard deviation is not known or the sample size is very small.

Assumptions of the t-test for the test to be valid:-

Data is independent.Data is collected randomly. For example, with simple random sampling.The data is approximately normally distributed.

Null hypothesis:  μ = $143,260

Alternative hypothesis: μ < $143,260

Calculating test statistic.

n = 30

sample mean = $135,000

sample standard deviation = $30,000

[tex]t_{0} = \frac{sample\ mean - population\ mean}{\frac{standard\ deviation}{\sqrt{sample\ size} } }[/tex]

[tex]t_{0} = \frac{135000 - 143260}{\frac{30000}{\sqrt{30} } }[/tex]

|to| = 1.508

Test criteria:

level of significance = 0.05

t(0.05, 29) = 1.6991

Since, |to| = 1.508 < t(0.05, 29) = 1.6991, null hypothesis cannot be rejected.
