Answer

a. -3/5

b. (0,2)

c. The line is decreasing.

Explanation

In this form, the number that accompanies the x correspond to the slope and the value of the independent number to the y-intercept.

The line is decreasing because the slope is negative.

There is a bag with only red marbles and blue marbles. The probability of randomly choosing a blue marble is 2/9 . There are 63
Verdich [7]

Answer:

49 red marbles

Step-by-step explanation:

There is a bag with only red marbles and blue marbles.

We are told in the question that:

The probability of randomly choosing a blue marble is 2/9 . There are 63 marbles in total in the bag

Hence: since

P(Blue marbles) = 2/9

Hence,

The number of blue marbles = 63 ÷ 9

= 7

Hence:

2 × 7/9 × 7 = 14/63

Hence, the number of blue marbles = 14 blue marbles

The number of red marbles bus calculated as:

63 - 14 blue marbles

= 49 red marbles

Find the cosine ratio of angle ?. hint: use the slash symbol ( / ) to represent the fraction bar, and enter the fraction with no
Andru [333]

We are given that the angle a is the right angle. So let us work from this.

ab = 12 (the vertical side of the triangle)

bc = 13 (which if drawn can be clearly observed to be the hypotenuse) = the side opposite to angle a

ca = 5 (the horizontal side of the triangle)

 

Since we are to find for the cosine ratio of angle c or angle θ, therefore:

cos θ = adjacent side / hypotenuse

cos θ = ca / bc

cos θ = 5 / 13

 

Check out the attached image below for the illustration of the triangle.

By how much is the product of 9/5 and 8 1/4 greater than 5
Oliga [24]

Given:

The product of \dfrac{9}{5} and 8\dfrac{1}{4} greater than 5.

To find:

By how much the product of \dfrac{9}{5} and 8\dfrac{1}{4} greater than 5.

Solution:

First we need to find the product of \dfrac{9}{5} and 8\dfrac{1}{4}.

\text{Product}=\dfrac{9}{5}\times 8\dfrac{1}{4}

\text{Product}=\dfrac{9}{5}\times \dfrac{8(4)+1}{4}

\text{Product}=\dfrac{9}{5}\times \dfrac{33}{4}

\text{Product}=14.85

Now subtract 5 from the product.

14.85-5=9.85

Therefore, the product of \dfrac{9}{5} and 8\dfrac{1}{4} is 9.85 greater than 5.
