Answer:

The percentage of deaths in relation to the number of cases is 4.55%.

Step-by-step explanation:

The proportion of deaths is the number of deaths divided by the number of cases(Proporção de mortes é o numero de morte dividido pelo de casos).

The percentage is the proportion multiplied by 100.

In this question:

3739 cases, 170 deaths

170/3739 = 0.0455

0.0455*100 = 4.55%

The percentage of deaths in relation to the number of cases is 4.55%.

Answer:

Step-by-step explanation:

Given that,

0 = 0.25x² - 8x

This is a quadratic equation, since it has the highest power of x to be 2.

0.25x² - 8x = 0

Simplify this by bring out x

x(0.25x - 8) = 0

So, if a × b = 0, it is either a = 0 or b = 0, if the multiplication of two number is 0, then it is either one of the number is 0 or both numbers is 0

So,

x(0.25x - 8) = 0

x = 0. OR. 0.25x - 8 = 0

x = 0. OR. 0.25x = 8

x = 0. OR. x = 8 / 0.25

x = 0. OR. x = 32.

So, the solution that describe the system is

0.25(0)² - 8(0)

OR

0.25(32²) - 8(32)

C. 104°. The measure of arc QR is equal to 104°.

In Mathematics and Euclidean Geometry, the inscribed angle of a circle is equal to one-half of the central angle or intercepted arc of a circle. This ultimately implies that, the measure of an inscribed angle is one-half the measure of the arc it intercepts based on the inscribed angle theorem.

Since angle S intercepts arc QR, the measure of the angle substended by the intercepted arc can be modeled by the following mathematical equation:

m∠S = 1/2(arc QR).

52 = 1/2 × arc QR

Arc QR = 2 × 52

Arc QR = 104°.

Answer: P(landing on orange)=1 - [2/3 + 1/12 + 1/12]

so =1/6

The probability of landing on orange is 1/6.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur.

The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Probability Formula = f/n

where,

f is the number of times an event occurs

n is the total number of trials

It is given that

The probability of landing on red is 2/3, on green 1/12, on blue is 1/12.

The probability of happening a event is P , then Probability of not happening is 1-P

the probability of landing on orange

= 1- { (2/3) +(1/12)+(1/12)}

=1/6

Therefore the probability of landing on orange is 1/6.

The probability of choosing one white sock and then another white sock from a drawer of 16 socks with 8 being white is 7/30, calculated by multiplying the probability of each event: (1/2) * (7/15).

Initially, there are 8 white socks out of 16 total socks in the drawer. After putting one white sock aside, there are now 7 white socks left out of 15 total socks in the drawer.

The probability for each event is calculated separately:
The probability of picking a white sock first: 8/16 or 1/2.
Then the probability of picking another white sock: 7/15.

To find the overall probability of both events occurring in sequence (one after the other), we multiply the probabilities of the two independent events:

(1/2) * (7/15) = 7/30.

So the correct answer is A. 7/30.

1/20 or 0.05

Step-by-step explanation:

Assuming that all five posters are different, the number of ways to randomly place those posters is given by:

[tex]N=5*4*3*2*1 = 120\ ways[/tex]

If we want the largest to be in the center and the next largest to be on its left, two poster will have a set position and only three could be randomized:

[tex]n=3*2*1*1*1=6\ ways[/tex]

Therefore, the probability is:

[tex]P=\frac{n}{N}=\frac{6}{120} =\frac{1}{20} =0.05[/tex]

The probability is 1/20 or 0.05.

Answer:

13 sq cm.

Step-by-step explanation:

To find the area of this irregular figure, we will need to find the areas of a rectangle and triangle within this figure.

To find the area of the rectangle, we can simply do:

1 × 4= 4  sq cm.

Now, this is where it gets a little trickier. To find the area of the triangle, we will first need to determine the base and height.

We can see from the diagram that to find the base, we need to subtract:

7-4= 3 cm. This is the base of ONLY the triangle.

To find the height, we will need to do:

5+1= 6 cm. This is the total height of the entirety of the triangle.

We can now use the Triangle Area formula: [tex]\frac{1}{2}[/tex](bh), to calculate the area of the triangle.

[tex]\frac{1}{2}[/tex] (6*3)= 9 sq cm.

Finally, add the areas of the rectangle and triangle together, giving you:

9+4= 13 sq cm.

Answer:

x=9

Step-by-step explanation:

Looking at the diagram, we see that four angles are formed by the intersection of two lines. The angles highlighted in blue and green are therefore, vertical angles. We know that vertical angles have equal angle measures meaning that in this case, the measure of the blue angle is equal to the measure of the green angle. Using this, we can now solve for x:

7x+49=2x+94

7x-2x=94-49

5x=45

x=45/5

x=9

Answer:

They form a proportion

Step-by-step explanation:

Take 66 songs and divide by 6 hours

66/6 = 11 songs per hour

Take 22 songs and divide by 2 hours

22/2 = 11 songs per hour

The rates are the same so they a proportional

The rates 66 songs in 6 hours and 22 songs in 2 hours do form a proportion, as both simplify to the same ratio of 11 songs per hour, indicating a consistent linear relationship between the number of songs and listening time.

The question asks if the rates of 66 songs in 6 hours and 22 songs in 2 hours form a proportion. To determine this, we check if the ratios are equivalent. The ratio for the first rate is 66 songs per 6 hours, which simplifies to 11 songs per hour (since 66 ÷ 6 = 11). The ratio for the second rate is 22 songs per 2 hours, which simplifies to 11 songs per hour (since 22 ÷ 2 = 11). Since both rates simplify to the same unit rate of 11 songs per hour, they indeed form a proportion. This shows that the rate at which songs are experienced is consistent across both periods, essentially indicating that the number of songs listened to scales linearly with the time spent listening.

Answer:Dudley is 50 feet from the flagpole.

Step-by-step explanation:

The situation is represented in the attached diagram. FL represents the flagpole.

A represents the position of Asher.

B represents the position of Baxter.

C represents the position of Cranby.

D represents the position of Dudley.

Looking at the diagram, Dudley is at the same level with Asher but eastwards of the flagpole. The distance of Dudley from the flagpole would be

100 - 50 = 50 feet

Final answer:

Dudley is 100 feet east from the flagpole after the friends have each moved from their starting positions.

Explanation:

The question describes four friends at different locations in relation to a flagpole, and we are asked to determine how far Dudley is from the flagpole after following the described steps by the friends. To solve this, we can visualize or draw a diagram to represent the positions of friends and use the Pythagorean theorem to find the distance Dudley is from the flagpole.

First, let's determine the position of Cranby.

Since Baxter moved 50 feet north from Asher's position and then Cranby moved 100 feet east from Baxter's position, we can see that Cranby is 100 feet east and 50 feet north of the flagpole.

Dudley, standing 50 feet south of Cranby, would thus be at the same north-south position as the flagpole but still 100 feet to the east.

Therefore, Dudley is 100 feet east of the flagpole.

Answer:

144π or 452.16

Step-by-step explanation:

Use the equation  V = πr²h  and solve for V to find volume

V = π(6)²(4)

V = 144π or 452.16

By setting up and solving the equation 4x = 5x - 4, we can find the value of x. Substituting the value of x into the expression for AM or MB, we can find the length of AB.

In order to find AB, we need to solve for x since AM and MB are given in terms of x. Since line L bisects AB at point M, AM and MB should be equal. So, we can set up the equation 4x = 5x - 4 and solve for x.

4x = 5x - 4

-x = -4

x = 4

Now that we have the value of x, we can substitute it back into one of the expressions for AM or MB to find the length of AB. Using AM = 4x, we have AB = AM + MB = (4 * 4) + (5 * 4 - 4) = 16 + 16 = 32.

Therefore, AB is 32 units long.
