The following figure is made up of 2 rectangles. Find the total area of the figure

givi [52]

Answer:

Supposing that every squre is 1cm^2 large

The rectangle A has an area of 32cm^2
The rectangle B has an area of 20cm^2

Total area: 52cm^2

Step-by-step explanation:

Rectangle area formula is B*H

(I made it in cm^2 'cause I'm from Europe)

Use the following prompt to answer the next 6 questions. Suppose we want to test the color distribution claim on the M&M’s w

vitfil [10]

Answer:

The claim on the M&M’s website is not true.

Step-by-step explanation:

A Chi-square test for goodness of fit will be used in this case.

The hypothesis can be defined as:

H₀: The observed frequencies are same as the expected frequencies.

Hₐ: The observed frequencies are not same as the expected frequencies.

The test statistic is given as follows:

$\chi^{2}=\sum\limits^{n}_{i=1}{\frac{(O_{i}-E_{i})^{2}}{E_{i}}}$

Here,

$O_{i}$ = Observed frequencies

$E_{i}=N\times p_{i}$ = Expected frequency.

The chi-square test statistic value is, 14.433.

The degrees of freedom is:

df = k - 1 = 6 - 1 = 5

Compute the p-value as follows:

$p-value=P(\chi^{2}_{k-1} >14.433) =P(\chi^{2}_{5} >14.433) =0.013$

*Use a Chi-square table.

The significance level is, α = 0.05.

p-value = 0.013 < α = 0.05.

So, the null hypothesis will be rejected at 5% significance level.

Thus, concluding that the claim on the M&M’s website is not true.

Answer:

B. a ⊥ d

Step-by-step explanation:

If lines "a" and "d" are in the same plane, they are perpendicular to each other. If not, there is no relationship between the lines.

Lines parallel to the same line are parallel to each other, so a║c. In the same plane, a line perpendicular to one of two parallel lines is also perpendicular to the other. (For example, one side of a rectangle is perpendicular to both of the adjacent sides, which are parallel to each other.)

The appropriate choice is ...

a ⊥ d

In 3 dimensions, ...

Consider a cube. A given edge will be perpendicular to both of the two edges it meets at a corner.

It will not intersect (has no "perpendicular" relationship to) either of the edges parallel to those that meet at the corner at the other end of the space diagonal.

Using just yes or no, can you make more than one triangle when you are given 3 different line segments?

iogann1982 [59]

Answer:

Step-by-step explanation:

A triangle is made up of three line segments therefore, it would be impossible to make multiple triangles with only 3 line segments. You could stretch the line segments but they would never make other triangles since each attempt would be missing one line segment. What can be done with these 3 line segments is making more than one type of triangle. For example, we can make acute triangles, an obtuse triangle, right triangles, etc.
