Answers

Answer: The answer is b !

Image attached should help

The line of best fit is:

y = 3.1x + 12.9

Option A is the correct answer.

We have,

The line of best fit can be expressed in the form of y = ax + b,

where a is the slope of the line and b is the y-intercept.

From the given LinReg results, we have:

a = 3.1

b = 12.9

Substituting a and b in the equation y = ax + b we get,

The line of best fit is:

y = 3.1x + 12.9

Thus,

The line of best fit is:

y = 3.1x + 12.9

A jar contains 3 red marbles, 6 blue marbles, 5 green marbles and 6 yellow marbles. Assume there is replacement.

Answers

I believe the answer would be 36/400, 9/100, or 9%

(I believe you are asking for the probability of picking blue then another blue )

So, in the jar, there are 20 marbles, 6 of which are blue, so pick one would be a 6/20 or 3/10 ≈ 33.3%

Assuming that you grabbed a blue marble then it was replaced with another blue marble, you would multiply 6/20 and 6/20 (the individual chances of getting one blue) and get 36/400, which simplifies to 9/100 or 9%

You play tennis regularly with a friend, and from past experience, you believe that the
outcome of each match is independent. For any given match you have a probability of 0.6 of
winning. The probability that you lose the next two matches is
(a) 0.16
(b) 0.40
(c) 0.64
(d) 0.36

Answers

B is your answer let me know if I’m wrong

The probability that you lose the next two matches is 0.4. The correct option is B.

What is probability?

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of samples

Given that you play tennis regularly with a friend, and from past experience, you believe that the outcome of each match is independent. For any given match you have a probability of 0.6 of winning.

The probability that you lose the next two matches is calculated as:-

Probability = 1 - 0.6

Probability = 0.4

Therefore, the probability that you lose the next two matches is 0.4. The correct option is B.

Look at the image I attached for reference as I explain. (I only labeled the angles that are relevant to the problem)

These triangles are congruent, as shown by the first equation.

When triangles are congruent, it means that the sides and angles are the same.

We can see that angles ∠ABC and ∠DEC are corresponding, which means that they have the same value.

We don't know ∠DEC, but we have two angles in that triangle that we do know. Since the angles in a triangle add up to 180, we have this equation:

180-65-55=∠DEC

60 = ∠DEC

So now we know that ∠DEC is 60 degrees.

Since ∠ABC and ∠DEC are equal:

2x=60.

Divide both sides by 2, and we get x =30.

A triangle has angle measures of 47 degrees and 92 degrees. What is the measure of the third angle?

Answers

Answer:

The missing angle is 41 degrees

Step-by-step explanation:

First of all, a triangle is measured at 180 degrees in total

To find the missing measurement for the third angle, add the 47 and 92 degrees together which would equal 139 degrees.

47+92=139 degrees

Next just subtract 139 from 180 to get your answer.

180-139=41 degrees

The answer is 41 degrees

The equation of graph of the transformed function is g ( x ) = ( x + 4 )² - 3

How does the transformation of a function happen?

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the first function be represented as f ( x )

Now , the value of f ( x ) = x²

Let the second function be g ( x )

Now , the vertex of the function is at A ( -4 , -3  )

When the function is shifted left by 4 units and down by 3 units , we get

g ( x ) = ( x + 4 )² - 3

Hence , the transformed function is g ( x ) = ( x + 4 )² - 3 and the graph is plotted

Brett has 100 feet of fence with which to make a rectangular cage for his dog. The area of the cage in square feet is given by the polynomial where w is the width of the cage in feet. What is the area of the cage if the width is 8 feet?

Answers

Answer:

Area of rectangle cage = 336 feet²

Step-by-step explanation:

Given:

Wire required for fencing = 100 feet

Width of rectangular cage = 8 feet

Find:

Area of rectangle cage

Computation:

Wire required for fencing = perimeter of cage

Perimeter of rectangular cage = 100 feet

2[l + b] = 100 feet

l + 8 = 50 feet

Length of rectangular cage = 42 feet

Area of rectangle cage = Length x Width

Area of rectangle cage = 42 x 8

Area of rectangle cage = 336 feet²

I don't know the first question, the test wouldn't tell me:/

Angle C, Angle Z, Angle A, and Angle W are all angles whose cosine equals 35 and the statement that Sin B is greater than Sin Y is false.

What is a similar triangle?

The two triangles are said to be similar that have the same proportion of sides and angles.

Corresponding sides are in the same ratio.

a/p = b/q = c/r

In triangle ABC

AB = 5, AC = 3, BC = 4

Cos A = base/ hypotenuse

          = 3/5

Cos B = base/ hypotenuse

          = 4/5

Cos C = base/ hypotenuse

          = 3/5

In triangle WYZ

Cos W = base/ hypotenuse

           =  3/5

Cos Z = base/ hypotenuse

          = 4/5

Hence, Angle C, Angle Z, Angle A, and Angle W are all angles whose cosine equals 35.

In triangle WYZ

WY = 13

In triangle ABC

CB = 24, AC = 10

Sin B = Perpendicular/ hypotenuse

         = 10/26

Sin Y = Perpendicular/ hypotenuse

        = 5/13

Since both angles are equal also they are similar to each other.

Therefore, the statement that Sin B is greater than Sin Y is false.
