Answer:

[tex]x = \frac{1}{4}[/tex]

Step-by-step explanation:

Step 1: Subtract [tex]\frac{3}{4}[/tex] from 1

[tex]1 - \frac{3}{4}\\\\= \frac{1}{4}[/tex]

Therefore, the point could be [tex]\frac{1}{4}[/tex]

Answer:

Equation 1,

[tex]x + 2y = 11[/tex]

Equation 2,

[tex]x - 2y = 11[/tex]

Take equation number 2.

[tex]x - 2y = 11 \\ x = 11 + 2y[/tex]

Substitute 'x' in Equation number 1.

[tex]x + 2y = 11 \\ 11 + 2y + 2y = 11 \\ 11 + 4y = 11 \\ 4y = 11 - 11 \\ 4y = 0 \\ y = \frac{0}{4} \\ y = 0[/tex]

y = 0.

So x,

[tex]x = 11 - 2y \\ x = 11 - 2(0) \\ x = 11 - 0 \\ x = 11[/tex]

x = 11.

Answer:

using elimination method multiply both equations by 2...then subtract equation 2 from 1

Answer:

a) 0.27 = 27% probability that a randomly chosen card holder has annual income $20,000 or less.

b) 0.778 = 77.8% probability that (s)he carries a balance

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

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

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

a) What is the probability that a randomly chosen card holder has annual income $20,000 or less?

20% of 30%(carry no balance).

30% of 70%(carry balance). So

[tex]P = 0.2*0.3 + 0.3*0.7 = 0.06 + 0.21 = 0.27[/tex]

0.27 = 27% probability that a randomly chosen card holder has annual income $20,000 or less.

b) If this card holder has an annual income that is $20,000 or less, what is the probability that (s)he carries a balance?

Conditional probability.

Event A: Annual income of $20,000 or less.

Event B: Carries a balance.

0.27 = 27% probability that a randomly chosen card holder has annual income $20,000 or less

This means that [tex]P(A) = 0.27[/tex]

Probability of a income of $20,000 or less and balance.

30% of 70%, so:

[tex]P(A \cap B) = 0.3*0.7 = 0.21[/tex]

The probability is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.21}{0.27} = 0.778[/tex]

0.778 = 77.8% probability that (s)he carries a balance

Step-by-step explanation:

Answer:78.5 square units.

Explanation:

Answer:

1/2

Step-by-step explanation:

Well, First let us find the amount of numbers in a die greater than 3.

Remember greater than 3 does not include 3.

We have 3 numbers, 4,5,6 that are greater than 3.

The probabilty of getting a rolling a number greater than 3 is 3/6.

The  probability of the coin landing on heads is 1/2.

BUT, the problem is only requiring for you to find the probabilty of rolling a dice greater than 3. (key words)

Which is 3/6 or simplified to 1/2.

Answer:

y = 54

Step-by-step explanation:

Once again we are going to use the inscribed angle and intercepted arc relationship where the inscribed angle is equal to half of the measure of the intercepted arc.

Angle "y" is the inscribed angle and its intercepted arc has a measure of 108°

So y = one half of 108

[tex]\frac{108}{2} =54[/tex]

So we can conclude that y = 54

Answer:

i am also trying to figure out a

Step-by-step explanation:

Given:

In the given triangle the measure of two angles are 102 degree and 28 degrees and the sides of the triangle are a, 27 cm, c.

To find:

The value of a.

Solution:

Let the given triangle be ABC, such that,

[tex]m\angle B=28^\circ[/tex]

[tex]m\angle C=102^\circ[/tex]

[tex]b=27\ cm[/tex]

Using angle sum property of triangles, we get

[tex]m\angle A+m\angle B+m\angle C=180^\circ[/tex]

[tex]m\angle A+28^\circ+102^\circ=180^\circ[/tex]

[tex]m\angle A=180^\circ-28^\circ-102^\circ[/tex]

[tex]m\angle A=50^\circ[/tex]

According to the Law of Sines:

[tex]\dfrac{\sin A}{a}=\dfrac{\sin B}{b}[/tex]

[tex]\dfrac{\sin 50^\circ }{a}=\dfrac{\sin 28^\circ }{27}[/tex]

[tex]\dfrac{27\times \sin 50^\circ }{\sin 28^\circ}=a[/tex]

[tex]\dfrac{27\times \sin 50^\circ }{\sin 28^\circ}=a[/tex]

[tex]a\approx 44.06[/tex]

Therefore, the value of a is about 44.06 cm.

Answer:

  $7200

Step-by-step explanation:

The amount of simple interest can be found from ...

  I = Prt . . . . . . . where principal P is invested at annual rate r for t years

__

The amount of compound interest can be found from ...

  I = P((1 +r)^t -1) . . . . . same variable definitions

__

The amount of simple interest earned is ...

  I = 12000·0.075·8 = 7200

The amount of compound interest earned is ...

  I = 12000(1.06^8 -1) ≈ 7126.18

In this scenario, the simple interest account earns more interest. If Lila chooses that one, the amount of interest earned is $7200.

Answer:

A≈471.24 is the surface area of the cylinder

58m^2 is the surface area of the triangular prism

Step-by-step explanation:

Solution

A=2πrh+2πr2=2·π·5·10+2·π·52≈471.2389

Triangle area formula

area = 0.5 * b * h , where b is the length of the base of the triangle, and h is the height/altitude of the triangle.

4(2.5)+8(6)

10+48=58m^2

Answer:

AI = 3.25in

IH = 4.2in

Area = 23.025in

Step-by-step explanation:

the length of AI =CD+EF+GH

AI=1.3+0.75+1.2 INCH

AI=3.25 INCHES

the length of IH= 9 INCH - 4.8 INCH

=4.2 INCH

THE AREA OF THE VISIBLE SIDE OF THE MODEL = AI+IH+GH+GF+EF+DE+CD+AB+BC

3.25+4.2+1.2+4.8+0.75+4.8+1.3+2.8875+2.8875 INCH

=26.075

Step-by-step explanation:

4<a<5

2<b<4   multiply

4x2 < axb < 5x4

8<ab < 20

Answer:

1<a/b<2.5

Step-by-step explanation:

bro you're gonna give me brainless ://

We are given 4<a<5 and 2<b<4 and are asked to find a/b.

Since there is a wide range of values of numbers from 4 to 5 and 2 to 4, there is no definite answer to this. However, we can take the most extreme values here and write them on the opposite ends of the inequality.

For example, the lowest value here is >4/4 (>1) because that is the smallest value from the first inequality divided by the largest value from the second inequality. The other extreme is the biggest value possible, which is <5/2 (<2.5).

Given these extremes, we can now rewrite the inequality.

(smallest value)<a/b<(largest value)

1<a/b<2.5

Answer:

A

Step-by-step explanation:

While fractions are more exact, it will always depend on the scenario. You aren't going to give the amount of money something is as a fraction, that will always be a decimal. However, in most math circumstances, fractions can get more straight to the point since there is no such thing as a truly repeating fraction.
