use the image to match the arc/angle measure.
(there is one more option that i wasn’t able to get in the photo it is 67°

Answers

Answer:

The following measurements are:

[tex]m\angle{STR}=23^\circ[/tex] (Option #4)

[tex]m{QT}=142^\circ[/tex] (Option #7)

[tex]mST=134^\circ[/tex] (Option #5)

[tex]mRQ=38^\circ[/tex] (Option #2)

Step-by-step explanation:

To begin, we can find the measure of [tex]\angle{STR}[/tex] by applying the inscribed angle theorem: an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.

Since the intercepted arc (RS) is 46 degrees, we have:

[tex]46=2\theta\\23=\theta[/tex]

Next, we can find the measure of arc QT using the same theorem. So,

[tex]QT=2(71)\\QT=142[/tex]

Notice that the chord RT is actually a diameter. From the theorem about the inscribed angle including a diameter, we know that the intercepted arc will have a measure of [tex]180^\circ[/tex]. Since the arc ST is part of the arc RST, and we know RS is [tex]46^\circ[/tex], we can set up and solve this equation:

[tex]RST = RS + ST\\180 = 46 + ST\\134 = ST[/tex]

We can use the same idea to find RQ. We know that RQT is [tex]180^\circ[/tex] and QT is [tex]142^\circ[/tex], so:

[tex]RQT = RQ + QT\\180 = RQ + 142\\38 = RQ[/tex]

Answers

From the table, it is found that there is a [tex]\frac{5}{12}[/tex] probability that parents will have 1 boy and 1 girl if they have a total of two children.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, out of 12 experiments, 5 resulted in one of each, hence:

[tex]p = \frac{5}{12}[/tex]

A trapezoidal prism undergoes a dilation. The surface area of the pre-image is 35 m². The surface area of the image is 315 m². The height of the pre-image is 5. 8 m. What is the height of the image? Enter your answer as a decimal in the box. M.

Answers


17.4 m - I took the test on k-12 and I got it wrong because I thought it was 52.2m. I reviewed the test and the correct answer said "17.4m"

The original object is called pre-image, and its dilated version is called image. The height of the image for the considered case is 17.4 m

How does dilation affect length, area, and volume of an object?

Suppose a figure (pre image) is dilated (dilated image) by scale factor of k.

So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:

L = k × M

where 'k' will be called as scale factor.

The linear things grow linearly like length, height etc.

The quantities which are squares or multiple of linear things twice grow by square of scale factor. Thus, we need to multiply or divide by to get each other corresponding quantity from their similar figures' quantities.

So area of first figure = k² × area of second figure

Similarly,

Volume of first figure = k³ × volume of second figure.

It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.

For this case, we're given that;

Surface area of pre-image = 35 m²Surface area of dilated image = 315 m²Height of pre-image = 5.8 mHeight of dilated image.

Let the scale fator of dilation be k.

Then:

So area of pre-image = k² × area of dilated image

Thus, we get:

[tex]35 = k^2 \times 315\\\\k = \sqrt{\dfrac{35}{315}} = 1/3[/tex]

(took positive root as scaling is done by non-negative factors as only magnitude matters mostly)

Thus, we get:

Height of pre-image = (1/3) × Height of dilated image (say h)

[tex]5.8 = (1/3) \times h\\h = 3 \times 5.8 = 17.4 \rm \: m[/tex]

Thus, the original object is called pre-image, and its dilated version is called image. The height of the image for the considered case is 17.4 m

Step-by-step explanation: To find the mean of any given data, you need to add all the data.  The work is below:

13 + 19 + 17 + 10 + 22 + 14 + 17 = 112.

Now that we've added all the data, we have to divide the data by 7, because that's how many numbers that are in this data.  The work is below:

112 / 7 = 16.

Therefore, the mean of this data is 16.

Please help I don't understand because of this depreciation stuff. I want to know which one will be a better buy​

Answers

So if i'm reading it right, it says the total depreciation will be 13% & 14% after the 5 years. If i'm misunderstanding, let me know and i'll fix my answer because the process will be a bit different

Depreciation means a decrease in something over time. You can think of it like a "__% off" sale if that helps

For the first option, we need to find 13% of 18,000. "Of" always means multiply, so 13%*18,000=2,340

Since we're decreasing, subtract 2,340 from the original cost

18,000-2,340=$15,660

Same process for the second option

14%*22,000=3,080

22,000-3,080=$18,920

Referring to question 1, what is the predicted strength of a weld with a diameter of 51?

Answers

The predicted strength is an illustration of a linear regression

The predicted strength of a weld with a diameter of 51 is -503.2

How to determine the predicted strength?

The equation of the predicted strength is given as:

Strength = -941.6992 + 8.5988*Diameter

Substitute 51 for diameter

Strength = -941.6992 + 8.5988*51

Evaluate the sum

Strength = -503.1604

Approximate

Strength = -503.2

Hence, the predicted strength of a weld with a diameter of 51 is -503.2

Linear regression strives to show the relationship between two variables by applying a linear equation to observed data.

The equation of the predicted strength is given as:

Strength = -941.6992 + 8.5988 × Diameter

Substitute 51 for diameter

Strength = -941.6992 + 8.5988 × 51
