Simplify the following 3 x a x 2 x b

Answer:

answer is 2.5 times....

There are 2.5 times does 2 go into 5.

Since, Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that,

To find what times does 2 go into 5.

Now, We can solve as by divide 5 by 2,

⇒ 5 / 2

⇒ 2.5

Thus, A number 5 is 2.5 times 2.

Probability of 1st/2nd/10th sample = 1/10

Step-by-step explanation:

All the possible combinations of the 3 size samples from a 5 size population have been listed without repetition.

Total Numbers of Samples = 10

To find the probability of finding the first sample from random sampling procedure,

Probability = Number of desired outcomes/ Total number of outcomes

Where Number of desired outcome is 1 and total number of outcomes is 10.

Probability = 1/10

Similarly, to find 2nd sample or 10th sample, the number of desired outcomes is same i.e 1, hecne the probability remains the same i.e 1/10

Possible samples:

(G,L), (G,S), (G,A), (G,P), (L,S), (S,A), (A,P), (L,P), (S,P), (A,L).

a) Given:

Answer:

whats the real answer?

Step-by-step explanation:

Answer:

(f+g)(x) = x²+5x-14 + (x-2)

           = x²+5x-14+x-2 = x²+6x-16

(f-g)(x) = x²+5x-14 - (x-2)

          = x²+5x-14 - x+2

          = x²+5x-14-x+2 = x²+4x-12

Answer: Slope of 2.

Step-by-step explanation:

Start at where the line meets on the y-axis, -7. Then work your way upwards until you see the line align with a value of x, like (1,-5). Then you see a trend of it going up 2 units and over 1. 2/1 or 2 is your slope.

Answer:

You would see the graph reflected over the x axis

Step-by-step explanation:

when there is a negative in front of the equation and not in the absolute value bars then it is a reflection over the x-axis...If there is a negative in front of the x in the absolute value bars then it is a reflection over the y-axis

Answer:

A= 30 years old

B= 20 years old

Step-by-step explanation:

Let the present age of A be x years old.

Since the sum of the present ages of A and B is 60 years,

present age of B= (60-x) years old

In 5 years

A= x +5

B= 60 -x +5= 65-x

Since the ratio of A:B= 4:3,

A would represent 4 units and B would represent 3 units.

Thus [tex]\frac{3}{4}[/tex]A=B

[tex]\frac{3}{4}[/tex](x+5)= 65 -x

[tex] \frac{3}{4} x + \frac{15}{4} = 65 - x \\ \frac{3}{4} x + x = 65 - \frac{15}{4} \\ \frac{7}{4} x = 61.25 \\ 7x = 61.25 \times 4 \\ 7x = 245 \\ x = 245 \div 7 \\ x = 35[/tex]

Thus, present age of A

= x

= 35 years old

present age of B

= 60 -x

= 60 -35

= 25 years old

5 years ago

A= 35 -5= 30 years old

B= 25 -5= 20 years old

* under the section in 5 years, [tex]\frac{3}{4} A=B[/tex] because both would be equal to 3 units each. Since B is 3 units and A is 4 units, in order to make both value the same, we divide the 4 units of A by 4 then multiply by 3 to get 3 units. Thus, [tex]\frac{3}{4}[/tex] of A is equal to B.

Answer:

d

Step-by-step explanation:

Given the x and y are in direct variation then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 12 when x = 4, that is

12 = 4k ( divide both sides by 4 )

3 = k

y = 3k ← equation of variation

When x = 20 , then

y = 3 × 20 = 60 → d

The value of the expression {(-3)⁰}/{(-3)²} is 1/9.

Exponentiation is one of the mathematics operations.

Let mᵃ, where m and a are the real numbers.

And m is multiplied by a times to itself.

So, a is the exponent of m.

Given:

Start Fraction (negative 3) Superscript 0 Over (negative 3) squared End Fraction

In numerator form:

{(-3)⁰}/{(-3)²}

Answer:

y = -8/15

Step-by-step explanation:

log (4y + 1) = log (y - 7) - 2log2

log (4y + 1) = log (y - 7) - log2² (power law)

log (4y + 1) = log [(y - 7)/4]

4y + 1 = (y - 7)/4 (remove log)

4(4y + 1) = y - 7

16y - y = -8

15y = -8

y = -8/15

Answer: [tex]-1\frac{1}{5}[/tex]

Step-by-step explanation:

[tex]2(P +1) + 3(P + 2 ) > 2[/tex]

Distribute 2 and 3

[tex]2P+2+3P+6>2[/tex]

Combine like terms;

[tex]5P+8>2[/tex]

Subtract 8

[tex]5P>2-8[/tex]

[tex]5P>-6[/tex]

Divide by 5

[tex]P>-\frac{6}{5}[/tex]

Convert to a mixed number by dividing. However, when we have the numerator greater than the denominator, we must find a way to make the numerator lower. We can achieve this by separating it into 2 fractions.

[tex]-\frac{6}{5}=-\frac{5}{5}-\frac{1}{5}[/tex]

When we do this, we can see that 5/5 = 1

[tex]-1-\frac{1}{5}=-1\frac{1}{5}[/tex]

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Since the cube fits perfectly in the sphere, it means that the diagonal of the cube will form the diameter of the sphere. In a cube, all sides are equal. To determine the length of its diagonal, d, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Therefore,

d² = 10² + 10² = 200

d = √200 = 14.14cm

Formula for finding the volume of a sphere is expressed as

Volume = 4/3 × π × r³

Radius of sphere = diameter/2 = 14.14/2 = 7.07cm

Volume = 4/3 × π × 7.07³ = 471.19π cm³

The value of [tex]x[/tex]:

[tex]x = 44[/tex]

Step-by-step explanation:

Find the value of [tex]x[/tex]:

[tex]2(x + 10) = 3(x-8)[/tex]

Use Distributive Property:

[tex]2(x + 10) = 3(x-8)[/tex]

[tex]2x +20 = 3x - 24[/tex]

-Subtract both sides by [tex]3x[/tex] and combine both [tex]2x[/tex] and [tex]-3x[/tex] together:

[tex]2x +20 - 3x = 3x - 3x - 24[/tex]

[tex]-x + 20 = -24[/tex]

-Subtract both sides by [tex]20[/tex]:

[tex]-x + 20 - 20 = - 24 - 20[/tex]

[tex]-x = -44[/tex]

Divide both sides by [tex]-1[/tex]:

[tex]\frac{-x}{-1} = \frac{-44}{-1}[/tex]

[tex]x = 44[/tex]

So, the final answer would be [tex]x = 44[/tex].

Answer:

Cross Multiplying

x × 8 = 5 × 3

8x = 15

Dividing both sides by 8

x = [tex]\frac{15}{8}[/tex]

OR

x = [tex]1 \frac{7}{8}[/tex]
