The probability of winning one prize in 3 attempts is P = 0.41.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given that, the chance of winning a prize is 0.45, Kyle plays the game 3 times. we need to find the probability that she wins at most 2 prizes

Out of 3 attempts, the probability of winning one prize is:

P(1) = (0.45)x(0.55)²p

where p is the number of permutations, you can win on the first attempt, second attempt, or third attempt, so there are 3 permutations.

Then the probability is:

P(1) = (0.45)x(0.55)²x3 = 0.41

Hence, the probability of winning one prize in 3 attempts is P = 0.41,

Answer: D 0.91

Step-by-step explanation:

Add 0.17 + 0.41 + 0.33 = 0.91

To get 0.17:

0.41 + 0.33 + 0.09 = 0.83

1 - 0.83 = 0.17

Answer:

2/5

Step-by-step explanation:

5-3/2-(-3)=2/5

The random variable r has a mean μ = 10 and σ = 4. For the variable s, the μ = 7 and σ = 3. The mean of r-s will be obtained by arithmetic subtraction of the μ for r and a. The standard deviation isn't independent since it's obtained by square root of the variance of a distribution. The standard deviation will be obtained by obtained through the square root of the squared sum of σ.

μ (r-s) = μ(r) -μ(s)

μ (r-s) = 10 -7 = 3

σ (r) -σ(s) = √(σ (r))²+ (σ (s))²

σ (r) -σ(s) = √(4²+ 3²)

σ (r) -σ(s) = √(16+ 9)

σ (r) -σ(s) = √25 = 5

thus, the mean is 3 and the standard deviation is 5.

Given:

The locations of the two points are (-3 , -8) and (3 , -8).

To find:

The relation between two points.

Solution:

From the given points (-3 , -8) and (3 , -8), it is clear that the y-coordinates are same but the sign of x-coordinates are opposite.

If a figure is reflected across the y-axis, then we change the sign of x-coordinate and the y-coordinates remain same, i.e.,

[tex](x,y)\to (-x,y)[/tex]

For (3,-8),

[tex](3,-8)\to (-3,-8)[/tex]

So, it is reflection across the y-axis.

Therefore, the correct option is C.

Step-by-step explanation:

12 - 1 = 11

to solve for q all you had to do was 12-11=1 (switch 11 and one)

Hey there!

11 = 12 - q

-q + 12 = 11

SUBTRACT 12 to BOTH SIDES

-q + 12 - 12 = 11 - 12

SIMPLIFY IT!
-q = 11 - 12

-q = -1

-1q = -1

DIVIDE -1 to BOTH SIDES

-1q/-1 = -1/-1

SIMPLIFY IT!

q = -1/-1

q = 1

Therefore, your answer should be:

q = 1

Add 2 to both sides

Answer:

18 and 13

Step-by-step explanation:

The two numbers are 13 and 18 respectively.

We have the difference of two integers is 5. Twice the smaller integer is 8 more than the larger integer.

Assume the number to be [x] and [y]. We can write -

x - y = 5

2y = x + 8

2y = 5 + y + 8

y = 13

Then -

x = 13 + 5

x = 18

Therefore, the two numbers are 13 and 18 respectively.

Step-by-step explanation:

Graph below.

Answer:

y = 2/5x + 2

Step-by-step explanation:

y = mx + b

First, we find out the slope. The slope is the change in y over the change in x.

The change in y is the second y-value subtracted from the first. The first y-value is 0 and the second is 2.

0 - 2 = -2

The change in x is the second x-value subtracted from the first. The first x-value is -5 and the second is 0.

-5 - 0 = -5

The slope is the change in y over the change in x.

-2/-5 = 2/5

y = 2/5x + b

b is the y-intercept, which is the value of y when x = 0.

When x = 0, y = 2 (0,2), so b = 2.

y = 2/5x + 2

Step-by-step explanation:

Let's solve your equation step-by-step.

4(x−6)+2=6x−2

Step 1: Simplify both sides of the equation.

4(x−6)+2=6x−2

(4)(x)+(4)(−6)+2=6x+−2(Distribute)

4x+−24+2=6x+−2

(4x)+(−24+2)=6x−2(Combine Like Terms)

4x+−22=6x−2

4x−22=6x−2

Step 2: Subtract 6x from both sides.

4x−22−6x=6x−2−6x

−2x−22=−2

Step 3: Add 22 to both sides.

−2x−22+22=−2+22

−2x=20

The resulting image of point C is C''(x, y) = (1, - 5).

The triangle seen on the Cartesian plane is generated by three points on that plane. The image of the triangle is the result of reflecting the three vertices over the x axis and later translating them 3 units in the +x direction and a unit in the - y direction, two kinds of rigid transformations.

Now we proceed to show the entire procedure:

Reflection over the x-axis

C'(x, y) = C(x, y) + (0, - 2 · c)

C'(x, y) = (- 2, 4) + (0, - 8)

C'(x, y) = (- 2, - 4)

Translation

C''(x, y) = (- 2, - 4) + (3, - 1)

C''(x, y) = (1, - 5)

The resulting image of point C is C''(x, y) = (1, - 5).

The roots of a function are the values of x for which f(x) = 0.

In this problem, we have that:

For values of x less than 2 on the interval, the function is never negative nor zero, hence there are no roots in that interval and option D is correct.

Given

[tex]c=9.3[/tex] in

a = x

we have to determine 'x'.

As the given triangle is a right-angled triangle.

Pythagorean Theorem:

For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as

[tex]c=\sqrt{a^2+b^2}[/tex]

so

[tex]a=\sqrt{c^2-b^2}[/tex]

Thus, the value of x:

Answer:

No, it doesn't.

Step-by-step explanation:

In order to find what makes a triangle, lets use the Triangle Inequality Theorem!

This theorem can help us show whether the sum of two side lengths of a triangle is greater than the third side or not

Here is our formula(s):

1.) a + b > c

2.) a + c > b

3.) b + c > a.

Lets make a=12, b=7, & c=5

1.) 12 + 7 > 5

    19 > 5

2.) 12 + 5 > 7

       17 > 7

3.) 7 + 5 > 12

      10 > 12

As you can see, both numbers 1 and 2 shows to be correct but 3 is not. Therefore it doesn't make a triangle. Remember, if all the two side lengths of a triangle is greater than the third side, then it makes a triangle.

Answer:

  April

Step-by-step explanation:

The sequence of amounts saved is a geometric sequence. The sum of those amounts is given by the formula ...

  Sn = a1·(r^n -1)/(r -1)

where a1 is the amount saved in month 1, r is the common ratio, and n is the number of months. We want to find n such that ...

  150 ≤ 5(2^n -1)/(2 -1)

  30 ≤ 2^n -1

  31 ≤ 2^n

We can solve this using logarithms, or we can make use of our knowledge of powers of 2: 2^5 = 32. That is, n = 5 will be the first month when Jordan's total savings exceeds $150.

The fifth month will be April. Jordan's total savings will be enough in April.

The attached shows a spreadsheet that computes Jordan's amount of savings each month, and his running total. Once the formulas are written, they can be copied down as far as required to see where the total savings is enough.
