What is the answer to this question.. What is 30% of 50?​

Answer:

x = 80

Step-by-step explanation:

We know AEC + CEB = 180 since it forms a line

AEC + 160 = 180

AEC = 20

We also know that

AEC + AEF + FED = 180 since it forms a line

20 + x+ 80 = 180

Combine like terms

100 +x = 180

Subtract 100 from each side

100+x-100= 180-100

x = 80

Answer:

D.) 73.7

Step-by-step explanation:

Took it on edge

The measure of angle B= 73.739.

Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a right-angled triangle with its angles. The ratios used to study this relationship are called trigonometric ratios, namely, sine, cosine, tangent, cotangent, secant, cosecant.

There are basic six ratios in trigonometry that help in establishing a relationship between the ratio of sides of a right triangle with the angle. If θ is the angle in a right-angled triangle, formed between the base and hypotenuse, then

given:

AC= 24, BC= 25

Now,

The opposite is the side facing the angle while the adjacent is the other third side.

Using Trigonometry

sin B = P/B

sin B= 24/25

sin B= 0.96

B= arc sin(0.96)

B= 73.739

The equation y = -4x2 is a parabola that opens downward due to the negative coefficient of the x² term, indicating it has a maximum value. The specific maximum value would depend on the values of x.

The equation y = -4x2 is a quadratic equation. In this case, the coefficient of the x² term is negative, which means the parabola opens downwards. In such situations, the vertex of the parabola represents a maximum value. Hence, y = -4x2 has a maximum value, not a minimum.

To find the actual maximum value, we would need more information, such as values for x. However, unless there are restrictions on the domain, this function does not have a highest maximum value number as it goes towards positive infinity on the y-axis. Instead, we refer to the maximum point being the peak of the parabola, where it turns from increasing to decreasing.

Answer:

The situations that show strong correlation are;

1), 3), 4)

Step-by-step explanation:

To answer the question, we analyze each of the options in turn as follows

1) Since the speed of a car is given by the distance covered per unit time or speed = distance/time then, speed is inversely proportional to time that is an increase in speed will lead to a decrease in time to cover a given distance hence there is a strong correlation implying causation

2) Here, we have that the profit of the company is the difference between the total revenue and the total cost hence;

Profit = Revenue - Cost

As advertising is a cost, increasing the advertising budget, increases the cost and where the revenue remains, constant the profit will decrease

Therefore there is no correlation between increasing the advertising budget and increase in profit

3) When the weather is hot, people get thirsty and will like to cool down their body temperature, hence more people buy ice cream to cool down and quench some thirst hence there is a strong correlation between increase in temperature and an increase in ice cream sales which implies  causation

4) For very low income employments, some employees seek excuses to try to make the most of their time hence whereby it is difficult to have another employee stand in for them, some employees may select the recognized excuse of being sick so as to explain absence from work, hence when the salary is increased, they will find more reasons to come to work hence there is a strong correlation between increase in salary and decrease in sick days.

Answer:

5. y = 2x + 4

6. y = (-1/2)x - 2

Step-by-step explanation:

5. We want to find the slope-intercept form of this, which is y = mx + b, where m is the slope and b is the y-intercept.

Slope is change in y divided by change in x. Here, let's take two random points: (-2, 0) and (0, 4). Then we have:

m = (4 - 0) / (0 - (-2)) = 4 / 2 = 2

The slope is thus 2.

The y-intercept is where the line crosses the y-axis. We see it does so at the point (0, 4), so b = 4.

Our equation is thus: y = 2x + 4.

6. Again, let's find the slope. Pick any two points: (-4, 0) and (0, -2). The slope will be:

m = (-2 - 0) / (0 - (-4)) = -2 / 4 = -1/2

Now, look at the point (0, -2); that's where the line crosses the y-axis, so the y-intercept is b = -2.

Thus, the equation is: y = (-1/2)x - 2.

Answer:

5. y = 2x + 4

6. y = -0.5x - 2

Step-by-step explanation:

5. Slope: (4-0)/(0--2) = 4/2 = 2

y-intercept: 4

y = 2x + 4

6. slope: (-2-0)/(0--4) = -2/4 = -0.5

y-intercept: -2

y = -0.5x - 2

Answer:

Theta =  120 degrees, 420 degrees, 480 degrees, 780 degrees, and 840 degrees

60 + 360 = 420 degrees,  

60 + 720 = 780 degrees,  

120 + 360 = 480 degrees,

120 + 720 = 840 degrees

Step-by-step explanation:

90  to 870 degrees for theta.

sin (theta) = root(3) /2

We see this comes from a 30-60-90 triangle.

theta is 60 degrees

but we want theta from 90 to 870 degrees.

120 degrees works too.

so we try to find all the co-terminal angles to 60 and 120 degrees that satisfy the conditions.

60 + 360 = 420 degrees,  

60 + 720 = 780 degrees,  

120 + 360 = 480 degrees,

120 + 720 = 840 degrees

Step-by-step explanation:

The probability that Jaime eats a cherry flavored jellybean first and a green apple flavored jellybean second, for the given condition, is given by: Option D: 5/78

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For two events A and B, by chain rule, we have:

[tex]P(A \cap B) = P(B)P(A|B) = P(A)P(B|A)[/tex]

where P(A|B) is probability of occurrence of A given that B already occurred.

For this case, we're specified that:

Let we take:

A = event that the first jellybean he chose is cherry flavored.

Then, as there are 10 ways to choose a cherry flavored jellybean, and 40 ways to choose a single jellybean randomly, so we get:

n(A) = 10, and n(choosing a random jellybean from a bag of 40 jellybean) = 40

Thus, we get: P(A) = 10/40 = 1/4 = 0.25

Now, let we take B = event that after eating first jellybean (first can be of any flavor), the second jellybean he eats is of green apple flavored.

For second random picking, there are only 39 jellybeans remaining.

P(B|A) = Probability that the second jellybean chosen is green apple flavored given that the first jellybean was cherry flavored.

Since if first jellybean was cherry flavored, so there are still 10 green apple flavored jellybean.

Thus, P(B|A) = 10/39

Using the chain rule, we get:

P(First jellybean is cherry flavored and second jellybean is green apple flavored) = [tex]P(A \cap B) = P(A)P(B|A) = \dfrac{10}{40} \times \dfrac{10}{39} = \dfrac{10}{156} = \dfrac{5}{78}[/tex]

Thus, the probability that Jaime eats a cherry flavored jellybean first and a green apple flavored jellybean second, for the given condition, is given by: Option D: 5/78
