Please help!You roll a 6-sided die two times.
What is the probability of rolling a number less than 4 and then rolling an odd number?
Write your answer as a percentage.
Answer:
rolling a number less than 4=
1,2,3 are less than 4 and a die is 6 sided so that will be 3/6 which in lowest terms is 1/2
1/2 as a percentage is 1/2*100=50%
rolling an odd number=
on a 6 sided die there are 3 odd numbers which are 1,3 and 5=
3/6 which in lowest terms is also 1/2
so 1/2*100=50%

Look at picture above. I need help to understand it. I’m not sure how to do it. And I can’t continue until I get this answer. Thank you
Answer:
1. Negative values of b would mean that y can fluctuate between a positive and negative answer depending on what is used for x. In simpler terms, if b < 0, y can be both less than and greater than 0. If b > 0, y can only be greater than 0. This means that only functions where b > 0 can be defined. You would not want to use negative values of b because the answer will not always be a natural number.
2. You cannot consider y = 1^x or y = 0^x to be exponential functions because, while they do utilize an exponent, they do not create exponential growth. 1 multiplied by itself, no matter how many times, will always result in 1. Similarly, 0 multiplied by itself will always result in 0. Therefore, no exponential growth is occurring in either of those equations. (I think this answer is more up to interpretation. I'm sure an argument can be made for those two equations to be considered exponential functions because they have exponents in them. The important thing to recognize here is that no growth occurs with either of them. Therefore, they are different from other "exponential functions").
Answer:
1. If you have a negative base and you try to take the square root of it you get an imaginary number.
2. To get the second point, raising 1 to x will always get you 1 and raising 0 to x will always get you 0.
Step-by-step explanation:
For example if you have the square root of -64, you get +8i and -8i since you're taking the square root. This means that there are no real roots. They're imaginary.
y = 1^x. if we chose the values: 1, 2, 3, 4 to be our x we will always end up with 1 as our answer. If you graph this, you will see a straight horizontal line at y = 1.
This is why it's not an exponential function. It doesn't behave the same way other exponential functions do. You can have a much better understanding if you use a graphing calculator to actually how it looks (try desmos online if you don't have a gc).
Now y = 0^x will also always result in an answer of 0. Take x as 1, 2, 3, 4. 0*0 = 0. 0 * 0 * 0 = 0. I think you get the point. Exponential functions show exponential growth while y = 1^x and y = 0^x are straight horizontal lines, not exponential functions.

Enter the equation of the circle with the given center and radius.
Center:(-4, 2); radius: 2
The equation is
Answer:
The answer is:
[tex](x+4)^2+(y-2)^2 = 4[/tex]
Step-by-step explanation:
The equation of a circle:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Since, you already have the center and the radius, use them for the equation of a circle and it will be written as:
[tex](x+4)^2+(y-2)^2 = 2^2[/tex]
When putting the equation of a circle, the radius needs to be simplified by the exponent [tex]2[/tex]:
[tex](x+4)^2+(y-2)^2 = 4[/tex]
So, you have found the equation of circle.

Answer:
989 square inches
Step-by-step explanation:
Let's start by finding the surface area of the bottom cube. It has six sides with side length 11, meaning that each side has area 11^2=121. Multiplying this by 5(since she's not staining the bottom), you get 605. For the second sphere, you can calculate this with the expression 6 * 8^2=384. Adding these together, you get a total surface area of 989 square inches. Hope this helps!
If a car travels at 40km/hr for 4 hours, how much distance has it covered?
If a car travels at 40 km/hr for four hours, it will have covered 160 km. A line or line segment's length between two points along the line or line segment
How to find the distance?To calculate distance, use the formula d = st, or distance equals speed times time. Both rate and speed represent some distance per unit time, such as miles per hour or kilometers per hour. The length of the line segment connecting two points in a plane is defined as distance between two points. The formula for calculating the distance between two points is typically given as d = √((x2 – x1)² + (y2 – y1)²). This formula is used to calculate the distance between two points on a coordinate plane or an x-y plane.Speed equals x distance over time, so to find distance, multiply the speed by the time.
For example, 40 km per hour times 4 hours equals 160 km after the 4 hour time period.
Then,
To put it another way,
40 × 4 = 160.
Hence, If a car travels at 40 km/hr for four hours, it will have covered 160 km.

How long was Anthony's family gone? Complete the explanation of how the answer can be found. To find the answer, count hour(s) from 5:05 to 6:05. Then count minutes to 6:35. Then count minutes to 6:45 and minutes to 6:51. I add them all up to get that the Anthony's family was gone hour(s) and minutes. Anthony's family went out to dinner. They left at the time shown on the clock. They returned home at 6:51 P.M.
Answer:
Thus, the Anthony's family were away for 1 hour 46 minutes
Step-by-step explanation:
We are being told that Anthony's family went out to dinner and they left at the time shown on the clock (i.e 5;05 P.M) and they returned home at 6:51 P.M.
We are to calculate how long was Anthony's family gone
We all know that:
60 seconds = 1 minute
60 minutes = 1 hour
So from 5:05 to 6:05 = 60 minutes
From 6:05 to 6:35 = 30 minutes
From 6:35 to 6:45 = 10 minutes
From 6:45 to 6:51 = 6 minutes
Therefore ; to deduce how long was Anthony's family gone; we will have to sum up the values of the minutes from the above time- frames up;
So; (60 + 30 + 10 + 6 ) minutes
= 106 minutes
since 60 minutes = 1 hour
Then 106 minutes = 1 hour 46 minutes
Thus, the Anthony's family were away for 1 hour 46 minutes

Answer:
Original: $733 million
Sequel: $860 million
Step-by-step explanation:
Let's say the original movie grossed x dollars. Since the sequel grossed 127 million more than that, we can write the expression x + 127 to represent the sequel.
Their total is 1593 million, so let's add them up:
x + (x + 127) = 1593
2x + 127 = 1593
2x = 1466
x = 1466/2 = 733
To find the sequel gross amount, add 127 to 733:
127 + 733 = 860
So, the original movie grossed $733 million, while the sequel grossed $860 million.

Step 1) Use the area formula to find the length of the radius
A = (3.14 x r^2) / 4
3.14 = (3.14 x r^2) / 4
12.56 = 3.14r^2
r^2 = 4
r = 2 feet
Step 2) Use the perimeter formula to find the perimeter
C = ((pi x 2r) / 4) + 2r
C = ((3.14 x 4) / 4) + 4
C = (12.56 / 4) + 4
C = 3.14 + 4
C = 7.14 feet

An artist uses 60 pounds of clay to make 80 bowls. The ratio of pounds of clay she uses to the number of bowls she makes is a proportional relationship. Select all the true statements.
Answer:
With the given information we can find the unit rate at least
We know that the artist used 60 pounds of clay to make 80 bowls. If we divide those magnitudes, we would find the total number of pounds per bowl.
[tex]p=\frac{60}{80}=0.75 \ lb/bowl[/tex]
Therefore, the artist used 0.75 pounds per bowl.
We can also express the proportional relationship as
[tex]clay=0.75(bowl)[/tex]
Which indicates that the total number of pounds of clay represents 75% of the total number of bowls, that's the relation.

Determine the minimum amount of packaging needed to completely cover a
triangular prism Oblerone bar with these dimensions: length 22.5 cm; triangular face
A right triangular prism has 3 rectangular faces.
If each of the edges of the triangular base measures 4.5cm,
and the length (the height) of the prism is 22.5cm,
the 3 rectangular faces (sides of the box) are rectangles,
22.5cm long and 4.5cm wide.
Each face has a surface area of (22.5cm)(4.5cm)=101.25 square centimeters.
The total lateral surface area for the 3 rectangular sides of the box is
3(101.2 square centimeters)=303.75 square centimeters.
If the triangular faces of the box are triangles
with a base measuring 4.5cm and a height measuring 4.0cm,
the surface area of each triangular face is
(1/2)(4.5cm)(4.0cm)=9 square centimeters.
The surface area of the two triangular faces adds up to
2(9 square centimeters)=18 square centimeters.
The total surface area for the box is
303.75 square centimeters + 18 18 square centimeters= 321.75 18 square centimeters,
and that rounds up to highlight 322 square centimeters.
NOTE:
The answer above is the one your teacher wants,
but there is a problem with this problem.
An equilateral triangle with sides measuring 4.5cm
would have a height of approximately 3.9cm.
