Answer:

A.) <em>m ∠ ABD = m ∠ CBD</em>

Step-by-step explanation:

The line segment BD was constructed as an angle bisector, which means that ∠  ABC was split directly in half. This means that the two resulting angles are congruent.

In order of blank boxes going from left to right then down will be 1, 9, 5, 75, 35.

The missing table is given below.

<h3>What are ratio and proportion?</h3>

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Shawn is collecting money from students at his school for a charity.

The table gives the ratios of the number of students who have donated and the amount of money he has collected from them.

Since 30 is 1/3 of 90, we know the ratio is 1:3.

In order of blank boxes going from left to right then down

1, 9, 5, 75, 35

The complete table is attached below.

More about the ratio and the proportion link is given below.

Write the slope-intercept form of the equation of the line described by (−1, −1), parallel to y = −2x − 4
LuckyWell [14K]

Answer:

y = -2x - 3

Step-by-step explanation:

Slope intercept form of line is

y = mx + c

where

m is the slope and c is the y intercept

________________________________________

Given that line

y = −2x − 4

comparing it with y = mx + c

m = -2 and c = -4

Thus, slope of this line is -2

we also know that when two lines are parallel then their slopes are same

thus, slope of required line will be m = -2

___________________________________________

now let the equation of line passing through (-1,-1) be

y = mx + c

we have found m to be -2

using this in above equation we have

y = -2x + c

since (-1,-1) passes through the above line using x = -1 and y = -1

we have

-1 = -2*-1 + c

-1 = 2 + c

c = -1 - 2 = -3

using c = -3 in y = -2x + c

we have

equation of line as

y = -2x - 3 in slope intercept form.

1)Why is the statement incorrect that probability can be used to predict the result of an activity?
vladimir2022 [97]

Answer with explanation:

→The Exact meaning of Probability is Chance.It Means ,that Something will happen or not in terms of rational numbers.

→As, Probability of an event lies between ,0 to 1, means ,the result is not Precise ,whether it will happen surely that is exactly 100% or it will not, that is 0%.Percentage of happening of anything lies between 0% to 100%.

→0 ≤ Probability ≤ 1,shows that ,if we represent it on the number line, it is Scattered from ,0 to 1.

These three reasons are enough to verify that, Probability can't be used to Predict exactly ,the result of an Activity.It is just representation in terms of rational number.

Use proportions.
214/236=x/100(100 because it's a percentage.
cross multiply:
