1. Ratio of medals won by Josephine to the total number won by the team: 1/13 (A)

2. Ratio of medals won by Jacob to medals won by Antonio: 2/1 (D)

Ratio can be described as a quantitative relation that compares how many times a value is contained in another.

1. Ratio of medals won by Josephine to the total number won by the team:

Total won by the team = 26

Medals won by Josephine = 2

Ratio = 2:26 = 2/26

= 1/13 (A)

2. Ratio of medals won by Jacob to medals won by Antonio:

Jacob = 8

Antonio = 4

Ratio = 8:4 = 8/4

= 2/1 (D)

Answer:

2.267742732288 × 1012

Step-by-step explanation:

Tammy must give Qiulian 800 cards, so that they have the same number of card.

Given the following data:

Translating the word problem into an algebraic expression, we have;

Qiulian and Tammy have 2400 cards:

[tex]Q+T=2400[/tex]    .....equation 1.

Tammy has twice as many cards as Qiulian:

[tex]T=2Q[/tex]   .....equation 2.

To determine the amount of card that Tammy must give Qiulian so that they have the same number of card:

Substituting eqn. 2 into eqn. 1, we have:

[tex]Q+2Q=2400\\\\3Q=2400\\\\Q=\frac{2400}{3}[/tex]

Q = 800 cards.

For Tammy:

[tex]T =2Q\\\\T=2\times 800[/tex]

T = 1600 cards.

Therefore, Tammy must give Qiulian 800 cards, so that they have the same number of card.

Answer:

I'm certainly late, but it took me a while to figure this one out so I want to leave an answer.

A=-5 B=2 C=19 D=-2

Step-by-step explanation:

I looked back at the video and actually tried to pay attention and the way to figure these problems out is set up all of the degrees of x in an equation. So, take all of the coefficients that are attached to an x^3, and set them up equal to each other. This makes -5=A, which is the first answer. Repeat for x^2 and you have B=2. For x, it becomes 9=2A+C. A is equal to -5 (from the x^3), so you can substitute and get c=19. Repeat for the x^0 term (the constants), and you get 2=2B+D. Plug in the value for B, 2, and get 2=4+D, which then becomes D=-2. That's how you get the answer and I hope this helps somebody.

The values are A=-5, B=2, C=19 and D=-2

Partial fractions are the fractions used for the decomposition of a rational expression. When an algebraic expression is split into a sum of two or more rational expressions, then each part is called a partial fraction. Hence, basically, it is the reverse of the addition of rational expressions.

Given:(-5x³+2x²+9x+2) / x²+2 =(Ax + B)/x²+2 + (Cx + d)/x²+2 .......(1)

First, we have to perform the long division as follows

The long division gives

(-5x³+2x²+9x+2 )/ x²+2= ( -5x+2)+ (19x-2)/ x²+2

Now, we have to find the partial fraction for  (19x-2)/ x²+2

But, as denominator cannot be factored, So no partial fraction can be calculated.

Thus, (-5x³+2x²+9x+2 )/ x²+2=  ( -5x+2)+ (19x-2)/ x²+2

Comparing it with equation (1), we get

Hence, A=-5, B=2, C=19 and D= -2

Answer:

x = 12.05

using sine rule:

[tex]\boxed{sin(a) = \frac{opposite}{hypotenuse} }[/tex]

Here given the angle is 35° and hypotenuse is 21.

To find x:

→ sin(35) = [tex]\frac{x}{21}[/tex]

→ x = 21 * sin(35)

→ x = 12.04510516

→ x = 12.05 ................rounded to nearest tenth.

Step-by-step explanation:

Number of 4 generated is 7 and number of 7 generated is 5.

Total of 7 + 5 = 12 outcomes out of 50:

The experimental probability of the computer generating a 4 or a 7 is D. 24%.

Experimental probability calculates the probability of some event from the results of experiments.

For an event E, we get the experimental probability of that event

[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]

where P_e(E) is denoting the experimental probability of occurrence of E.

A computer generates 50 integers from 1 to 8 at random. The results are recorded in this table.

Outcome 1 2 3 4 5 6 7 8

Number of times outcome occurred

5 8 9 7 4 6 5 6

The Total of 7 + 5 = 12 outcomes out of 50:

The experimental probability of the computer generating a 4 or a 7

P(4 or 7) = 12/50

Answer:

[tex]5\sqrt{185}t[/tex]

Step-by-step explanation:

after time t (hr), the distance between A and starting point is 40t

the distance between B and starting point is 55t

These two distances are perpendicular to each other, so

the distance between A and B is

[tex]\sqrt{(40t)^2+(55t)^2}=\sqrt{4625t^2}=5\sqrt{185}t[/tex]

Medians bisect eachother at centroid in ratio 2:1

SU is perpendicular bisector

UY=UZ

So

Apply Pythagorean theorem

[tex]\\ \tt\hookrightarrow VY^2=XS^2-VS^2=80^2-48^2=6400-2304=4096\implies VY=64[/tex]

Answer:

XS = 80

YZ= 132

VY = 64

Step-by-step explanation:

Firstly, SU is a perpendicular bisector

so, UV= UZ and YZ = 2(66) = 132

Each median bisect each other at centre with the ratio 2 : 1

therefore ZS = 80 = XS

now , by using P.G.T

VY² = XS²-VS²

=> 80²-48²

=> 6400-2304

=> 4096

=> √4096

=> 64

VY = 64

The Bernoulli counting process depicts that the value of X6 will be 0.

The value of X6 will be:

= N6 - N5

= 3 - 3

= 0

Also, the value of S3 will be:

X1 = 1 - 0 = 1

X2 = 1 - 1 = 0

X3 = 1 - 1 = 0

Therefore, S3 will be:

= X1 + X2 + X3

= 1 + 0 + 0

= 1

In conclusion, the value of S3 is 1.

Step-by-step explanation:

we know that sum of all angles of a triangle is 180°

so, angle N + angle O + angle M = 180°

=> (-5b+16)+(-b+8)+(-9b-9) = 180°

=> -5b+16-b+8-9b-9 = 180°

=> -15b+15 = 180°

=> -15b = 180-15

=> -15b = 165

=> b = -165/15

=> b = -11

angle N => -5(-11)+16

=> 55+16 => 71

angle O => -(-11)+8

=> 11+8 => 19

angle M => -9(-11)-9

=> 99-9

=> 90
