Step-by-step explanation:

cross-multiply

4y = -2

y = -2/4

y = -1/2

Answer-

y=-1/2

Multiply each side by -2 to isolate the variable.

1/4 x -2 = -1/2

For the coin: 2 possibilities, either head or tail. So probability of head is 1/2.

For the cube (assuming numbers are 1 to 6): 6 possibilities (1 2 3 4 5 6). We have 3 odd numbers, so probability of odd number is 3/6=1/2.

You want both head and an odd number, so you multiply the 2 probabilities: 1/2×1/2=1/4.

So the answer is 1/4.

You can use a tree to better understand probabilities.

Answer:

I guess the answer is 4.4 cm or 22/5 cm

Step-by-step explanation:

AREA= 15cm^2

Let the Breadth be x

Length= 4x-7

Area = l×b

15 = 4x-7×x

15+7=4x+x

22=5x

22÷5=x

4.4=x

Therefore, Breadth= 4.4cm Length= 10.6cm

Step-by-step explanation:

(E)lsa + (C)hang + (B)ob=104

C=3B

E=B+6

substitute

(B+6)+3B+B=104

5B+6=104

5B=98

5B/5=98/5

B=19.60

E=19.60+6=25.60

C=3(19.60)=58.80

Answer: x = 2.

Step-by-step explanation:

By an online search, i found that the question is:

"Given that x satisfies the inequality 20*x > 33,  find the smallest value of x if x is a prime number."

To find the smallest value of x we need to input different possible values of x (where we have the condition that x must be a prime number) and see which one is the first one that makes the inequality true.

The prime numbers are:

2, 3, 5, ....

Let's start with the smaller one, x = 2

So we input it in the inequality and get:

20*2 > 33

40 > 33

this is true.

Then we can have x = 2, which is the smaller prime number that satisfies the inequality.

Answer:

6.6

Step-by-step explanation:

The length of i is 6.6 units(after the nearest 10th of a centimeter) if in ΔIJK, k = 7.2 cm, ∠J=55°, and ∠K=67°.

The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have a triangle:

As we know the sum of the triangle is 180°

So I = 180 - 55 - 67 = 58°

Applying sin law to calculate the value of i:

[tex]\rm \frac{i}{sin58} = \frac{k}{sin67}[/tex]

[tex]\rm i = \frac{7.3\times sin 58}{sin67}[/tex]

i = 6.633 units ≈ 6.6 units   (sin58 = 0.848, and sin67 = 0.920)

Thus, the length of i is 6.6 units(after the nearest 10th of a centimeter) if in ΔIJK, k = 7.2 cm, ∠J=55°, and ∠K=67°.

Answer:

28.86

Step-by-step explanation:

According to the scenario, computation of given data are as follows,

Exponential smoothing a = 0.1

we can calculate forecast for each week by using following formula,

Forecast for week = Forecast of last week + a × ( actual calls of last week - forecast of last week)

By using this method, forecast for all week are as follows

Answer:

"in an average of" / "approximately"

Step-by-step explanation:

these clue words do not hold any definite value. therefore, it can be used for estimating.

Answer:

We conclude that:

[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]

The solution graph on the number line is also attached.

Step-by-step explanation:

Given the inequality

[tex]-8x\:\le 32[/tex]

Solving the inequality

[tex]-8x\:\le 32[/tex]

Multiply both sides by -1 (reverse the inequality)

[tex]\left(-8x\right)\left(-1\right)\ge \:32\left(-1\right)[/tex]

Simplify

[tex]8x\ge \:-32[/tex]

Divide both sides by 8

[tex]\frac{8x}{8}\ge \frac{-32}{8}[/tex]

Simplify

[tex]x\ge \:-4[/tex]

Therefore, we conclude that:

[tex]-8x\le \:32\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]

Answer:

A = 3

B = 8

C = 2

D = 5

Step-by-step explanation:

The language is solved and the four digit code is given by

A = 3

B = 8

C = 2

D = 5

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

2 + 1 = A

On simplifying the equation , we get

A = 3

Now , 3 + 5 = B

B = 8

And , D + 3 = 8

Subtracting 3 on both sides , we get

D = 5

And , 3 + C = 5

Subtracting 3 on both sides , we get

C = 2

Hence , the four digit code is A = 3 , B = 8 , C = 2 , D = 5

Answer:

[tex](x,y) = (0,7)[/tex]

[tex](x,y) = (3,7)[/tex]

Step-by-step explanation:

The question and the attached image are different. However, the attached image answers the question y = -4 correctly.

So, I will solve for: [tex]y = -x + 7[/tex]

Given

[tex]y = -x + 7[/tex]

Required

Possible values of x and y

Let x = 0:

[tex]y = -x + 7[/tex]

[tex]y = -0 + 7[/tex]

[tex]y = 7[/tex]

So, we have:

[tex](x,y) = (0,7)[/tex]

Let y = 4

[tex]y = -x + 7[/tex]

[tex]4 = -x + 7[/tex]

Collect Like Terms

[tex]x = -4 + 7[/tex]

[tex]x =3[/tex]

So, we have:

[tex](x,y) = (3,7)[/tex]

So, all you need to do is: assume a value for either x or y, then solve for the other variable.
