What is the answer to x-(9x-10)+11=12x+3(-2x+1/3

If two of these shapes are randomly chosen, one after the other without replacement, what is the probability that the first will

aleksandrvk [35]

Answer:

$P(T\ n\ S) = \frac{1}{14}$

Step-by-step explanation:

*Missing Part of the Question*

4 stars

5 triangles

3 circles

3 squares

Required

Determine the probability of triangle being first then square being second

$Total = 4 + 5 + 3 + 3$

$Total = 15$

Represent the triangle with T and square with S

So, we're solving for P(T n S)

$P(T\ n\ S) = P(T) * P(S)$

Solving for P(T)

$P(T) = \frac{n(T)}{Total}$

$P(T) = \frac{5}{15}$

Solving for P(S)

The question implies a probability without replacement;

Hence Total has now been reduced by 1

Total = 14

$P(S) = \frac{n(S)}{Total}$

$P(S) = \frac{3}{14}$

Recall that

$P(T\ n\ S) = P(T) * P(S)$

$P(T\ n\ S) = \frac{5}{15} * \frac{3}{14}$

$P(T\ n\ S) = \frac{15}{15 * 14}$

$P(T\ n\ S) = \frac{1}{14}$

Hence, the required probability is

$P(T\ n\ S) = \frac{1}{14}$

What is the slope of the line graphed on the coordinate plane

Mice21 [21]

Answer:

The slope = 3/4

Step-by-step explanation:

$m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$m=\frac{6-3}{2-(-2)}=\frac{6-3}{2+2}$

m = 3/4

The distance from a point to a line is the length of the ____________ segment from the point to the line.

solniwko [45]

Answer: 1) Perpendicular

2) Concurrent

Step-by-step explanation:

The distance from a point to a line is the length of the perpendicular segment from the point to the line.

As Perpendicular segment is the shortest distance to the point of the line.

When three or more lines intersect at one point, they are concurrent.

Because Concurrent is a situation when three or more lines intersect each other at a single point.

What the anwser fast !!!!!!

Vlad1618 [11]

Answer:

The initial height is the y-intercept of the graph

slope of the graph = -2

Jordon interprets the only the slope correctly.

Aral interprets the only the initial height correctly.

Step-by-step explanation:

Slope = change in y ÷ change in x = (0 - 12) ÷ (6 - 0) = -12 ÷ 6 = -2

So the slope of the graph = -2

by inspection, the y-intercept = 12

Therefore, the equation for the line is y = -2x + 12

Jordon interprets the only the slope correctly.

Aral interprets the only the initial height correctly

Elena surveyed her classmates to see how many like to make jewelry. When she asked 20 of her classmates, 50 percent said they li

nordsb [41]

10 students of Elena's classmates like to make jewellery.

<u>Step-by-step explanation:</u>

Let total no.of classmates who liked the jewellery = x

Here, in the given problem, given she asked her classmates '20'. So, it clearly shows that total number of students/classmates = 20. Also, in that, 50% said like to make jewellery. Now find 'x' as below,

$x = 50 \% \text { of } 20$

$x = \frac{50}{100} \times 20$

$x = 10$

Hence, the total number of classmates who liked to make Jewellery = 10
