If there are five choices on a multiple choice test, what is the probability of guessing any of them correctly?

1 answer:

4 0

C. 1/5. Because there is only one answer that is the right answer to each multiple choice. Also, there are 5 choices for us to choose.

Can someone solve this?

Answer:

1. 15 degrees.

2. 90 degrees.

3. 66 degrees.

Step-by-step explanation:

M and 2 appear to be 90 degrees. This is because there are parallel sides on the left and right of the kite. So, 2 is 90 degrees.

E and 75 are corresponding (I don't remember the postulate or whatnot) so 90 degrees plus 75 degrees is 165 degrees. There are 180 degrees in a triangle, so 180 minus 165 is 15. 1 Has to be 15 degrees.

3 is 66 degrees since it is corresponding with the angle on the other side of T (I, once again, do not remember the postulate).

Answer:

Step-by-step explanation:

$u=5i-j\\\\v=3i+j\\\\w=i+4j\\$

$v+w$

$3i+j+i+4j\\\\4i+5j\\\\u*(v+w)\\\\(5i-j)(4i+5j)\\\\20-5\\\\\boxed{15}$

Bridgette made a graph of her neighborhood on a coordinate grid. The points A(-2, 3), B(-2, -2), C(2, -2), and D(2, 3) represent

vodka [1.7K]

Answer:

$\boxed{\text{18 blocks}}$

Step-by-step explanation:

Distance travelled on graph = AB + BC + CD + DA

AB = CD = (3 +2) = 5

BC = AD = 2 –(-2) = 4

Distance on graph = 2 × 5 + 2 × 4 = 10 + 8 = 18 spaces = 18 blocks

Bridgette jogs $\boxed{\textbf{18 blocks}}$ each day.

The perimeter of the kitchen is 528 inches if the width of the kitchen is 120 inches what is the length of the kitchen

butalik [34]

Answer: 144 inches.

Step-by-step explanation:

1. To solve this problem you must remember the formula for calculate the perimeter of a rectangle, which is shown below:

$P=2l+2w$

Where $l$ is the lenght and $w$ is the width.

2. You know the perimeter and the width, then you can solve for the length, as following:

$P-2w=2l\\l=\frac{P-2w}{2}\\l=\frac{(528in)-(2*120in))}{2}\\l=144in$
