Answer:

  C.  ΔABE≅ΔDBC by SAS

Step-by-step explanation:

Only two sides are marked as congruent. So, any claim using SSS is automatically false. (SSS requires 3 corresponding sides be congruent.)

Of the claims citing SAS, the one regarding ΔABD is false. The points A, B, and D are on the same line, so do not form a triangle.

The only correct claim is that of C: ΔABE≅ΔDBC by SAS

Answer:

The last one: 25%

Step-by-step explanation:

Answer: 274.75

Step-by-step explanation:

To find the volume of a cylinder you find the area of the base and then multiply it by the height. The base is the radius (half the diameter) squared times pi which we will use 3.14. That gets us 78.5. Then we multiply by the height to get 274.75!

Hope this helps!

The capacity/volume of the cylinder is approximately: 274.89 cm³

capacity of a cylinder = volume of cylinder = πr²h.

Given the following:

Capacity/Volume of the cylinder = π(5²)(3.5)

Capacity/Volume of the cylinder ≈ 274.89 cm³

Answer:

a. When the sample standard deviation is used to estimate the population standard deviation

Step-by-step explanation:

T or Z distribution:

If we have the standard deviation for the sample, we use the t-distribution.

If we have the standard deviation for the population, we use the z-distribution.

Thus, the correct answer for this question is given by option a.

Answer:

He should keep his job.

Step-by-step explanation:

We know that there is a 70% chance that he willend up getting a 10% raise. A 10% raise will allow him to make 66000 dolllars, which is 1000 more than getting a new job.

There is a 30% chance that he will make about 3,100 dollars less than a new job. However, 30% is much lower than 70%, so this probably wont be the outcome. And over future years, if this remains constant, he will end up still making more money staying wiht his job.

Step-by-step explanation:

Probability is the chance of an event to occur from a number of possible outcomes.

The probability that a marble chosen at random is red is 1/2.

It is the chance of an event to occur from a number of possible outcomes.

It is given by:

Probability = Number of required events / Total number of outcomes

We have,

Total number of marbles in the bag = 6

Number of red marbles = 3

Number of yellow marbles = 1

The number of blue marbles = 2

The probability that a marble chooses is red:

= Number of red marbles / total number of marbles

= 3 / 6

= 1 / 2

Thus,

The probability that a marble chosen at random is red is 1/2.

Step-by-step explanation:

The answer would be 40

Here's why:

1. (5+3+2)= 10

2. 10x4

3. 40

The expression represents the number of points Frank lost would be (5+3+2) x 4.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Frank lost 5 points for not completing his homework, 3 points for talking, and 2 points for chewing gum.

This happened 4 days in a row.

The expression represents the number of points Frank lost.

(5+3+2) x 4

Answer:

x = 30º

Step-by-step explanation:

This answer requires trigonometry, specifically, the cosine function. This is because we are given the length of the side adjacent to x and the length of the hypotenuse.

If you recall:

[tex]cos(x )= \frac{adjacent}{hypotenuse}[/tex]

Therefore,

[tex]cos(x) = \frac{13}{35}[/tex]

Now, we must use the inverse cosine function on a calculator to figure out the value of x.

[tex]cos^{-1}(\frac{13}{15}) = 29.93[/tex]

Now, we must round it to the nearest whole number, so x = 30º.

Answer:(0,10)

Step-by-step explanation:

The points On circle with a center at (0, 0) that includes the point (-1, -3) would be (0, 10).

If a circle O has a radius of r units length and that it has got its center positioned at (h, k) point of the coordinate plane,

then, its equation is given as:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

We have given On circle with a center at (0, 0) that includes the point (-1, -3).

So the equation form

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

[tex](x-0)^2 + (y-0)^2 = r^2\\\\x^{2} +y^{2} =r^{2} \\\\(-1)^{2} +(-3)^{2} =r^{2} \\\\r^{2} = 10[/tex]

So, the other point that satisfies the equation would be (0, 10).

Answer:

p = -5

Step-by-step explanation:

7(p + 1) = 2(3p + 1)

Distribute on both sides.

7p + 7 = 6p + 2

Subtract 6p from both sides.

p + 7 = 2

Subtract 7 from both sides.

p = -5

Answer:

p = -5

Step-by-step explanation:

7(p + 1) = 2(3p + 1)

Distribute

7p +7 = 6p +2

Subtract 6p from each side

7p +7 -6p = 6p+2-6p

p+7 = 2

Subtract 7 from each side p+7-7 =2-7
