Answer:

The missing value y=12.5 and we have (5,12.5)

Step-by-step explanation:

The formula used for direct variation is:

[tex]y\: \alpha \:x\\y=kx[/tex]

We need to find missing value (2,5)(5,y)

First we will find k, and then y

We have x=2, y=5

Find k:

[tex]y=kx\\5=k(2)\\k=\frac{5}{2}\\k=2.5[/tex]

Now, we cam find missing value in (5,y)

We have x=5, k=2.5 and y=?

[tex]y=kx\\y=2.5(5)\\y=12.5[/tex]

So, the missing value y=12.5 and we have (5,12.5)

Answer:

a=9

Step-by-step explanation:

2/3 (a-18)=-6

a−18=−6×( 3/2)

a−18=−6×3/2

a−18= −18/2

a−18=−9

a=−9+18  

a=9

​

Answer:

A=9

Step-by-step explanation:

Simplify both sides of the equation.

2/3(a−18)=−6

(2/3)(a)+(2/3)(−18)=−6(Distribute)

2/3a+-12=-6

2/3a-12=-6

Add 12 to both sides.

2/3a−12+12=−6+12

2/3a=6

Multiply both sides by 3/2

(3/2)* (2/3a)= (3/2)* (6)

A=9

Answer:

[tex]2[/tex]

Step-by-step explanation:

For this I would find two friendly points like (60,10) and (70,30). Now we will plug in for the slope-intercept formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].

So...

[tex]y_2=30\\y_1=10\\x_2=70\\x_1=60[/tex]

Now we plug in and solve...

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{30-10}{70-60}\\m=\frac{20}{10}\\m=\frac{2}{1}=2[/tex]

So the slope will be 2.

Answer: D) 13y^25 and 2y^25

Like terms involve the same variables, and each of those variables must have the same exponents.

Another example of a pair of like terms would be 5x^3y^2 and 7x^3y^2. Both involve the variable portion "x^3y^2" which we can replace with another variable, say the variable z. That means 5x^3y^2 becomes 5z and 7x^3y^2 becomes 7z. After getting to 5z and 7z, it becomes more clear we have like terms.

Answer:

All of the statements are true

Step-by-step explanation:

Given that :

Number of trials (n) = 100

Expected number of successes = 55

The number of successes of the 100 trials :

Number of successes / number of trials = 55 / 100 = expected number of successes / n = 55/ 100 = 0.55

Using Normal approximation :

Standard deviation (σ) = √(npq) ; q = 1 - p = 1 - 0.55 = 0.45

σ = √(100 * 0.55 * 0.45) = √24.75 = 4.975

The probability distribution of x = B(n, p) = x = B(100, 0.55)

Using approximation ; N(p, σ) = N(55, 4.97)

Hence, All of the statements are true

Answer:

[tex]P(R\ and\ B) = 0.0256[/tex]

Step-by-step explanation:

Given

[tex]Red = 22[/tex]

[tex]Yellow = 38[/tex]

[tex]Green = 20[/tex]

[tex]Purple = 28[/tex]

[tex]Blue = 26[/tex]

[tex]Orange = 16[/tex]

Required

Determine the probability of red then blue jelly? i.e. P(R and B)

From the question, we understand that the red jelly bean was not replaced. This means that the number of jelly beans reduced by 1 after the picking of the red jelly bean

So, we have:

[tex]P(R\ and\ B) = P(R)\ and\ P(B)[/tex]

This is then solved further as:

[tex]P(R\ and\ B) = P(R)\ *\ P(B)[/tex]

[tex]P(R\ and\ B) = \frac{n(R)}{Total}\ *\frac{n(B)}{Total - 1}[/tex]

The probability has a denominator of Total - 1 because the number of jelly beans reduced by 1 after the picking of the red jelly bean

The equation becomes:

[tex]P(R\ and\ B) = \frac{22}{150}\ *\frac{26}{150- 1}[/tex]

[tex]P(R\ and\ B) = \frac{22}{150}\ *\frac{26}{149}[/tex]

[tex]P(R\ and\ B) = \frac{22*26}{150*149}[/tex]

[tex]P(R\ and\ B) = \frac{572}{22350}[/tex]

[tex]P(R\ and\ B) = 0.02559284116[/tex]

[tex]P(R\ and\ B) = 0.0256[/tex]

Step-by-step explanation:

pounds / dollars =

You have to answer 2 questions.

1. Which axis are you reading first. Hint the question says pounds to dollars.

So you must be reading the x axis first. because it is pounds.

2. Where would the next point on the graph go.

You read along the x axis first. 25

then you read along the y axis. 20

The answer is 25,20 and that's where the next point goes.

Answer: 162

Work: 152 - 30 which equals 122, then add 40, and you get 162.

Answer:

Initial investment= $777.78

Step-by-step explanation:

Giving the following information:

Last year Hank cashed out his investment account that earned 4.5% simple interest after 10 years of investing. He ended up with $350 in interest on the account.

To calculate the principal (initial investment), we need to use the following formula:

I= P*r*t

I= $350

r= 0.045

t= 10

P= ?

350= P*0.045*10

350/0.45 = P

$777.78= P

Answer:

first is a function second third ad fourth arent function

Step-by-step explanation:

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The collection of values that could result in a function's outputs is known as the co-domain.

Given:

As, we know the relation is said to be a function if we have distinct inputs.

If the inputs are repeated then it is not a function.

So, {(3, 2),(6, 4),(9, 6),(12, 8)} is a function.

Also, {(2, 3),(2, 5),(3, 6),(9, 4)} is not a function.

{(2, 4),(6, 3),(4, 8),(6, 6)} is not a function.

{(3, 4),(5, 2),(6, 8),(6, 4)} is not a function.

Answer:

(c) Rs. 1500

Step-by-step explanation:

Percentages

It's given Kamal spent 40% of his income. With the remaining 60%, he deposited Rs. 400 in a bank and still has Rs. 500 left.

This means Rs. 400 + Rs. 500= Rs. 900 is 60% if his income.

The 100% of his income is calculated as a percent proportion:

If 60% is Rs. 900, then 100% is:

[tex]\displaystyle \frac{900}{60}*100=1500[/tex]

Thus, Kamal's income is Rs. 1500. Correct choice: (c) Rs. 1500
