Answer:

20/81.

Step-by-step explanation:

There are 5 odd numbers in 1 to 9 and 4 even ones.

Prob(Odd number on first spin) = 5/9

Prob(Not flipping heads on second) = 1/2

Prob(Not spinning a 6 on third ) =  8/9

The compound probability is found by multiplying the above ( because each trial is independent of the others):

Answer = 5/9 * 1/2 * 8/9

= 40/162

= 20/81.

It's probably A (I can't tell you for certain, because I can't see the image, but the other options seem illogical).

The bar graph presents the number of students who received each letter grade on a written report, enabling a clear comparison of quantities.

The statement about the graph that is true: The bar graph displays the number of students who earned each letter grade on a written report, making it suitable for comparing quantities. For example, the bar that represents the number of students who received an A appears to be shorter than the bar for students who received a C, indicating fewer students got an A.

Answer:

5.5

Step-by-step explanation:

gradient = (7-(-4))/(-4-(-6)) = 11/2 = 5.5

Answer:

P(sum is even) = 1/16 + 9/16 = 10/16

= 5/8

P(sum is odd) = 3/8

E(x) = (5/8)(6) + (3/8)(-2) = 3

Answer:

Order is 6

Step-by-step explanation:

The population of Portland Oregon has recently grown to more than 500,000.

The order of magnitude for the number of people in Portland means the power of 10. It means that we need to write 500,000 in form of 10 to the power. So,

[tex]P=500,000[/tex]

It contains 6 zeroes. It means,

[tex]P=5\times 10^6[/tex]

So, the order of magnitude for the number of people in Portland is 6.

Answer:  f(x) = (x + 3)(x – 7)

Step-by-step explanation:  Use "standard form" of the function and insert values given: vertex (2,-25) intercept point (7,0)

f(x) = a(x-h)² + k   from vertex, h is 2   y is -25   from intercept,  x is 7  f(x) is 0

to find a,  0 = a(7-2)² +(-25)   0 = a(7-2)² -25  add 25 to both sides

25 = a(5)²  25 = 25a  25/25 = a  1=a  (seems useless but verifies implied "a"coefficient is 1)

f(x) = a(x-h)² + k solve to get the quadratic form

f(x) = (x-2)² -25     (x - 2)² is x² -4x +4

f(x) = x² -4x +4 -25  simplify

f(x) = x² -4x - 21   then factor

f(x) = (x + 3)(x - 7)

Answer:

f(x) = (x + 3)(x - 7)

Answer:

3.6 cm

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2 (b1+b2)*h

We know the area of 4.5  and the top is 1 and the bottom is 1.5

4.5 = 1/2 (1+1.5) h

4.5 = 1/2 (2.5) h

4.5 =1.25h

Divide each side by 1.25

4.5/1.25 = 1.25h/1.25

3.6 =h

Answer:

[tex]3.6 \: \: cm[/tex]

Step-by-step explanation:

[tex]area \\ 4.5 = \frac{1}{2}(a + b ) \times h \\ 4.5 = \frac{1}{2} (1 + 1.5) \times h \\ 4.5 = \frac{1}{2} \times 2.5 \times h \\ 4.5 = \frac{2.5h}{2} \\ 4.5 = 1.25h \\ \frac{4.5}{1.25} = \frac{1.25h}{1.25} \\ h = 3.6 \: cm[/tex]

Answer:

i'm pretty sure it's B. X=-24 and x=24

Step-by-step explanation:

The average rate of change for a square root function decreases as we look at intervals of fixed lengths over the domain and the endpoints of those intervals increase. This is due to the property of the square root function where it's an increasing function but at a decreasing rate.

The average rate of change of a function measures how the output (y-value) changes in comparison to the input (x-value). For a square root function like f(x) = √x, as we look at intervals of fixed lengths over the domain and as the endpoints of those intervals increase, the average rate of change decreases.

This happens because the slope of the tangent line to the function (which represents the rate of change) gets progressively less steep as x increases. Square root functions are increasing functions but at a decreasing rate. For example, the slope between the points (1,1) and (4,2) on the function f(x) = √x is 1/3, but between (4,2) and (9,3), it's 1/5, indicating a decrease in the rate of change.

Answer:

500 cm2

Step-by-step explanation:

The dimensions of the prism are 7 cm, 9 cm and 20 cm.

So the three areas we want to find are three rectangles, with the sides:

7 cm and 20 cm, 9 cm and 20 cm, 9 cm and 20 cm

The area of each rectangle is:

rectangle_1 = 7 * 20 = 140 cm2

rectangle_2 = 9 * 20 = 180 cm2

rectangle_3 = 9 * 20 = 180 cm2

Summing all these three areas, we have:

Total area = 140 + 180 + 180 = 500 cm2

Answer:

x = 39

Step-by-step explanation:

To solve for x, we have to get it by itself in the equation.

In this problem, we have to do the opposite of subtraction and add 36 to the left and right side of the equation.

3 + 36 = x - 36 + 36

36 + 3 is equal to 39 and -36 + 36 cancels out.

This leaves us with 39 = x.

Answer:

Convert   4.5% to a decimal. 6000,0.045, 8 years

Step-by-step explanation:

I used math--way

The value of the account after 8 years with continuous compounding is approximately $8593.76.

To find the value of the account after 8 years with continuous compounding, we can use the formula for continuous compounding:

A=P⋅e rt

Where:

A is the amount of money accumulated after

t years, including interest.

P is the principal amount (the initial amount of money).

r is the annual interest rate (in decimal).

t is the time the money is invested for, in years.

e is the base of the natural logarithm, approximately equal to 2.71828.

Given:

P=$6000

r=4.5%=0.045 (in decimal)

t=8 years

Substituting the values into the formula:

A=6000⋅e 0.045⋅8

Now, let's calculate this:

A=6000⋅e 0.36

A≈6000⋅2.71828 0.36

A≈6000⋅1.432292989

A≈8593.757934

Rounding to two decimal places, the value of the account after 8 years with continuous compounding is approximately $8593.76, which is slightly different from the provided answer of $8532.60. This discrepancy might be due to rounding differences or calculation variations.
