Hey there! I'm happy to help!

Let's pretend that we are building a small sundae. We have 3 choices of ice cream flavors.

Now, we want to pick a topping. We have 4 choices here.

After we choose a topping, we can pick another. We only have 3 choices now because we need different toppings, and we already used one.

We want to find how many possible combos we can make. What we do is multiply all of these numbers of choices, and this will show us how many possible sundaes there are.

3×4×3=36

Therefore, there are 36 different sundaes that can be made.

Have a wonderful day! :D

The value of x in the triangle is given by trigonometric relations and the value is x = 8.86 units

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangle be represented as ABC

Now , the height of the triangle is BC = 5.5 units

Let the angle be θ = 50°

Now ,

From the trigonometric relations ,

cos θ = adjacent / hypotenuse

Substituting the values in the equation , we get

cos θ = 5.5 / x

Multiply by x on both sides of the equation , we get

x ( cos θ ) = 5.5

Divide by cos θ on both sides of the equation , we get

x = 5.5 / cos θ

when θ = 50°

x = 5.5 / cos 50°

x = 5.5 / 0.642787

x = 8.556 units

Therefore , the value of x = 8.56 units

Hence , the value of x of triangle is x = 8.56 units

Step-by-step explanation:

First of all, let us understand the meaning of dilation.

Dilation means to change the size of any image or line or a figure.

Dilation can be used to enlarge (dilation by a factor greater than 1) the original figure.

OR

Dilation can be used to make the image smaller (dilation by a factor lesser than 1) the original figure.

Here, we are given that an image with 4 points ABCD is dilated by a scale factor of [tex]\frac{1}{3}[/tex].

Its sides will be AB, BC, CD and DA.

Perimeter is equal to the sum of all the sides of a closed figure.

So, perimeter of ABCD = AB + BC + CD + DA = 27 units ...... (1)

Now, it is dilated by a scale factor of [tex]\frac{1}{3}[/tex].

So, all the sides will become smaller i.e.

A'B' = [tex]\frac{1}{3}[/tex] AB

B'C' = [tex]\frac{1}{3}[/tex] BC

C'D' = [tex]\frac{1}{3}[/tex] CD

D'A' = [tex]\frac{1}{3}[/tex] DA

Perimeter of A'B'C'D' = A'B' + B'C' + C'D' + D'A' = [tex]\frac{1}{3}[/tex]AB + [tex]\frac{1}{3}[/tex]BC + [tex]\frac{1}{3}[/tex]CD + [tex]\frac{1}{3}[/tex]DA

[tex]\frac{1}{3}[/tex] (AB + BC + CD + DA ) = [tex]\frac{1}{3} \times 27[/tex](By equation (1))

Perimeter of A'B'C'D' = 9 units

[tex][3,4][/tex] : [tex]r = 1[/tex], [tex][4,5][/tex] : [tex]r = 0.59[/tex], [tex][5,6][/tex] : [tex]r = 0.42[/tex]

Step-by-step explanation:

Given a function [tex]f(x)[/tex] that is continuous on [tex][a,b][/tex], the average rate of change is:

[tex]r = \frac{f(b)-f(a)}{b-a}[/tex]

[tex]a[/tex], [tex]b[/tex] - Lower and upper bounds, dimensionless.

[tex]f(a)[/tex], [tex]f(b)[/tex] - Images of the function evaluated at lower and upper bounds, dimensionless.

Let be [tex]f(x) = \log_{2}(3\cdot x - 6)[/tex], then:

[tex][3,4][/tex]

[tex]a = 3[/tex] and [tex]b = 4[/tex]

[tex]f(3) = \log_{2}[3\cdot (3) - 6][/tex]

[tex]f(3) \approx 1.585[/tex]

[tex]f(4) = \log_{2}[3\cdot (4) - 6][/tex]

[tex]f(4) \approx 2.585[/tex]

[tex]r = \frac{2.585-1.585}{4-3}[/tex]

[tex]r = 1[/tex]

[tex][4,5][/tex]

[tex]a = 4[/tex] and [tex]b = 5[/tex]

[tex]f(4) = \log_{2}[3\cdot (4) - 6][/tex]

[tex]f(4) \approx 2.585[/tex]

[tex]f(5) = \log_{2}[3\cdot (5) - 6][/tex]

[tex]f(5) \approx 3.170[/tex]

[tex]r = \frac{3.170-2.585}{5-4}[/tex]

[tex]r = 0.59[/tex]

[tex][5,6][/tex]

[tex]a = 5[/tex] and [tex]b = 6[/tex]

[tex]f(5) = \log_{2}[3\cdot (5) - 6][/tex]

[tex]f(5) \approx 3.170[/tex]

[tex]f(6) = \log_{2}[3\cdot (6) - 6][/tex]

[tex]f(6) \approx 3.585[/tex]

[tex]r = \frac{3.585-3.170}{6-5}[/tex]

Step-by-step explanation:

Answer:

∠ 2 = 45°

Step-by-step explanation:

∠ 1 and ∠ 2 are same- side interior angles and are supplementary, thus

∠ 2 = 180° - ∠ 1 = 180° - 135° = 45°

Answer: 45

Step-by-step explanation:

Answer:

(a) An ineffective sample may be found about 42 times in 1000 samples.

(b) Yes, the drug is evidently effective at alpha = 0.05.

(c) A drug that had a p-value of 0.042 is more effective in comparison to a drug that had a p-value of 0.087.

Step-by-step explanation:

We are given that a statistical study reported that a drug was effective with a p-value of 0.042.

Let the Null Hypothesis, [tex]H_0[/tex] : The drug was ineffective.

Alternate Hypothesis, [tex]H_A[/tex] : The drug was effective.

(a) An ineffective sample may be found about 42 times in 1000 samples.

(b) As we know that, if the P-value is less than the level of significance, then we have sufficient evidence to reject our null hypothesis.

SO, here also; the P-value is less than the level of significance as 0.042 < 0.05, so we reject our null hypothesis and conclude that the drug is evidently effective.

(c) The drug that had a p-value of 0.087 would be ineffective as in this case the P-value is more than the level of significance as 0.087 > 0.05, so we do not reject our null hypothesis and conclude that the drug is evidently ineffective.

This means that a drug that had a p-value of 0.042 is more effective in comparison to a drug that had a p-value of 0.087.

Answer:

0.6955x

Step-by-step explanation:

Given the following :

Promotional discount on items = 35%

Sales tax on items = 7%

Original cost of items = x

First we obtain the cost of item after the promotional discount is applied

Cost of item :

Original price - (original price * promotional discount)

x - (x * 0.35) = x - 0.35x

Cost of item = 0.65x

Then the sales tax is added :

Total amount after tax:

Cost of item + (cost of item × sales tax rate)

0.65x + (0.65x * 0.07)

0.65x + 0.0455x

= 0.6955x

Answer:

x and y do not show direct variation

Step-by-step explanation:

Two quantities x and y show direct variation when

y = kx

and k ≠ 0

Given x = y + 2

Making y the subject of the formula:

y = x - 2

The equation above cannot be written in the form y = kx

This means that x and y are not in a proportional relationship

For instance, let's say when x = 4

y = (4) - 2 = 2

Now, if x is doubled, x = 8

y = (8) - 2 = 6

Therefore, doubling x does not necessarily double y, hence they are not in a direct variation.

Scientific notations are the way through which a very small or a very large number can be written in shorthand.  In scientific notations when a number between 1 and 10s is multiplied by a power of 10.

For example, 6,500,000,000,000 can be written as 6.5e+12.

Given that the Water covers about 1.385 x 10⁸ square miles of Earth's surface. The area is given in scientific notations, this can be written in the standard form as shown below,

1.385 x 10⁸ square miles = 138,500,000 square miles

Answer:

5×17-8

Step-by-step explanation:

First you multiply 5 by 17 and then you subtract 8

Answer:

Angle 1= 63°

Angle 2 = 21°

Angle 3 = 96°

On the first roll, you have a 1/3 probability of rolling a 1 or 2 and thus winning $200.

There's a 2/3 probability of not rolling a 1 or 2 on the first roll. On the second roll, there is again a 1/3 probability of rolling a 1 or 2, and 2/3 probability otherwise, so that there is a 1/3*2/3 = 2/9 probability of getting a 1 or 2 and thus winning $100, and 2/3*2/3 = 4/9 probability of losing.

(a) Let [tex]W[/tex] be a random variable representing the winnings from playing the game. It has the probability mass function

[tex]P(W=w)=\begin{cases}\frac13&\text{for }w=\$200\\\frac29&\text{for }w=\$100\\\frac49&\text{otherwise}\end{cases}[/tex]

(b) Compute the expected value of [tex]W[/tex]:

Step-by-step explanation:

Answer: D. No; the graph fails the vertical line test.

The vertical line test is a tool used to determine if we have a function. If we can draw a single straight vertical line through more than one point on the red curve, then the graph is said to have failed the vertical line test. Consequently, this leads to the relation not being a function.

For this circle graph, we can draw a vertical line through more than one point, which is why we don't have a function here.

Put another way, there are inputs (x) that produce more than one output (y), so that's why we don't have a function.
