Mathematics
1 answer:
Margaret [11]2 years ago
8 0

Answer:

F. 30  G. 8

Step-by-step explanation:

F. 9 / 9 + 6 = 18 / BC

9 + 6 = 15

9 / 15 = 18 / BC

9 x 2 = 18

15 x 2 = 30

G. 9 / 6 = 12 / EC

9/6 reduces to 3/2

3/2 = 12/EC

3 x 4 = 12

2 x 4 = 8

Question 3 (Essay Worth 10 points) (05.07 MC) The scatter plot shows the number of strawberries that have been picked on the far
solong [7]

It's not an accurate value for the data based on the scatter plot, r = 0.01 is not an accurate value for this data, because 0.01 means practically no correlation, while the points on the graph are moderately correlated

<h3>How to illustrate the information?</h3>

1. Part A:

Since the points in the scatter plot show a moderated upward trend, you must expect a correlation coefficient close to ± 0.5. A correlation coefficient of 0.01 is too close to 0, which would mean that the points are almost not correlated at all.

The correlation coefficients, r, measure the strength of the correlation of two variables and they can have values from - 1 to  1.

Here, r = - 1 is a perfect negative correlation as the points will adjust perfectly to a line with negative slope.

r =  + 1 is a perfect positive correlation: the points will ajdust perfectly to a line with positive slope.

r = 0 means that the variables are not correlated at all.

Hence, the closer to zero, the worse the correlation is, and that is what r = 0.01 means, but the graph shows other thing.

Therefore, the calculated value of r = 0.01 is not accurate for this scatter plot.

2. Part B.

A causal relationship means that the explanatory variable (the independent variable) is the cause of the dependent variable.

Hence, you must find a reasonable variable that can be the cause of the number of strawberries picked.

Thus, the scenario could be:

Amout of rainfall in mm (x)         Number of strawberries picked (y)

      100                                                     20

        50                                                     40

        25                                                     80

        12.5                                                  160

        6.25                                                 320

The amount of rainfall is the cause of the number of strawberries picked, and you could find a model that relates both variables.

Round 479.16 to the nearest tenths
tatyana61 [14]

The tenths place would be the digit right after the decimal point, and we want to round 479.16 to the nearest tenths.

The number in the tenths place is 1. Now we have to decide if we're going to round up or down

  • If the next digit is greater than or equal to 5, we round up (add 1 to the digit); if it isn't, then we round down (the digit stays the same).

The digit after the tenths place is "6", which is greater than 5. Thus, the "1" is rounded up to a "2"

Answer: 479.16 to the nearest tenths is 479.2.

Let me know if you need any clarifications, thanks!

Look at thetriangles diagram.<br> The value of x is ___ °
NemiM [27]

By solving a linear equation we will see that the value of x is 10.

<h3></h3><h3>How to find the value of x?</h3>

Remember that for any triangle, the sum of all internal angles is always equal to 180°.

Here only look at triangle BCD, we know that:

m∠DBC = m∠ABC = 3x

m∠BCD = m∠ACB + m∠ABD = 2x + 65°

m∠ADC = 65°

Now we can write the linear equation as:

3x + 2x + 65° + 65° = 180°

5x + 130° = 180°

5x = 180° - 130°

5x = 50°

x = 50°/5 = 10°

The value of x is 10.
