Marcia biked 600 meters on friday. On saturday, she biked 3 kilometers. One sunday she biked 2 kilometers and 700 meters. How many kilometers did Marcia bike over the three days?
Answer:
6.3 km
Step-by-step explanation:
You want to know the total distance represented by segments of 600 m, 3 km, and 2km plus 700 m.
KilometerKilo- is a prefix meaning 1000. A kilometer is 1000 meters. That means we can write the distances as ...
600 m = 0.600 km3 km = 3.000 km2 km + 700 m = 2.700 kmTotalThe total of these distances is found by adding the decimal values in the usual way.
0.600 +3.000 +2.700 = 6.300
Marcia biked 6.3 km over the three days.

Final answer:
The equation formed based on the information that Paul halves the number to get 6 is x/2 = 6. Multiplying both sides by 2 gives us x = 12, which is the original number that Paul was thinking of.
Explanation:
The student question regarding forming an equation from a given word problem can be translated into: Paul halves the number and gets 6. To form an equation with x, we represent the unknown number as x, and then create an equation based on the information given. Since halving the number results in 6, the equation we form is x/2 = 6.
To find the value of x, we can multiply both sides of the equation by 2, which will give us x = 6 × 2. This simplifies to x = 12, which is the original number Paul was thinking of.

Answer:
The equation to describe the situation is [tex]p-3=17.[/tex]
And, the total weight of the basket of apples was 20 pounds.
Step-by-step explanation:
The question is incomplete so, the complete question is below:
Liang bought a basket of apples to make pies for her friends. The basket of apples weighed p pounds. Before she had time to make the pies, she ate 3 pounds of apples. There are 17 pounds of apples left to make pies. Write an equation to describe this situation. What was the total weight of the basket of apples?
Now, to write an equation to describe the situation. And to find the total weight of the basket of apples.
So, the basket of apples total weighed = [tex]p\ pounds.[/tex]
Liang ate apples weighed = 3 pounds.
And the apples left for the pies weighed = 17 pounds.
Now, to write an equation describing the situation:
[tex]p-3=17.[/tex]
Thus, the equation is [tex]p-3=17.[/tex]
Now, to get the total weight of the basket of apples:
[tex]p-3=17\\\\Adding\ both\ sides\ by\ 3\ we\ get:\\\\p=20[/tex]
Hence, the basket of apples total weighed = 20 pounds.
Therefore, the equation to describe the situation is [tex]p-3=17.[/tex]
And, the total weight of the basket of apples was 20 pounds.
The points J(-1,-9) and K(5,1) are endpoints of a diameter of circle S. Which equation represents circle S?
Answer:
(x -2)² +(y +4)² = 34
Step-by-step explanation:
The center of the circle is the midpoint of the line segment:
S = (J +K)/2 = ((-1, -9) +(5, 1))/2 = (4, -8)/2 = (2, -4)
The radius of the circle is the distance between the center and either end point. We want the square of the radius for our formula.
r² = (5 -2)² +(1 -(-4))² = 9 +25 = 34
The equation of a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
Using the numbers we have found, the equation for circle S is ...
(x -2)² +(y +4)² = 34
Answer:
(x-2)² + (y+4)²=34

We are standing on the top of a 960 foot tall building and launch a small object upward. The object's vertical altitude, measured in feet, after t seconds is h ( t ) = − 16 t 2 + 64 t + 960 . What is the highest altitude that the object reaches?
Answer:2 seconds s(2) max ht = 264 ft two answer pick one at least
Step-by-step explanation:
..A person standing cloes to the edge on the top of a 200-foot building throws a baseball ... t = -b/2a t = -64/-32
The highest altitude the object reaches is 1024 feet.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
h(t) = -16t² + 64t + 960
Now,
h'(t) = -16 x 2t + 64 = -32t + 64
h''(t) = -32
This means,
h(t) has a maximum altitude at h'(t) = 0
Now,
h'(t) = 0
-32t + 64 = 0
-32t = -64
t = 2
Now,
h(2) = -16 x 2² + 64 x 2 + 960
h(2) = -16 x 4 + 128 + 960
h(2) = -64 + 128 + 960
h(2) = 1024 feet
Thus,
The highest altitude is 1024 feet.

You wonder if TV ads are more effective when they are longer or repeated more often or both. So you design an experiment. You prepare 30-second and 60-second ads for a camera. Your subjects all watch the same TV program, but you assign them at random to four groups. One group sees the 30-second ad once during the program; another sees it three times; the third group sees the 60-second ad once; and the last group sees the 60-second ad three times. You ask all subjects how likely they are to buy the camera. (a) This is a randomized block design, but not a matched pairs design. (b) This is a matched pairs design. (c) This is a completely randomized design with one explanatory variable (factor). (d) This is a completely randomized design with two explanatory variables (factors). (e) This is a completely randomized design with four explanatory variables (factors).
Answer:
d) This is a completely randomized design with two explanatory variables (factors).
Step-by-step explanation:
Explanatory variables are independent variables.
In this case, I prepared two explanatory variables, which are : (i)30-second ad

Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 464 randomly selected adults showed that 64% of them would erase all of their personal information online if they could. Find the value of the test statistic.
Answer:
The value of the test statistic = 6.03
Step-by-step explanation:
The test statistics for a proportion of the population is the z calculated as follows;
[tex]z=\frac{\hat{p}-p}{\sqrt{\frac{pq}{n}}}[/tex]
Where:
[tex]\hat{p}[/tex] = 0.64
From the rule of large numbers we have, the proportion of adults who will erase their information online will tend towards 1/2 or 0.5 therefore, we have
p = 0.5 as the test
q = 1 - p = 1 - 0.5 = 0.5
n = Sample size = 464
Therefore, z is given by;
[tex]z=\frac{0.64-0.5}{\sqrt{\frac{0.5 \times 0.5}{464}}}[/tex]
= 6.03
The value of the test statistic = 6.03.

A coin tosses 100 times 52 heads and 48 tail what is the probability of flipping a tail on the coin
Answer:
The answer is 48/100 or 12/25
Step-by-step explanation:
Since there is 48 tails and 100 times flipped the answer would be 48/100 and if you ask for the probability of flipping the heads that would be quite the same and its 52/100. So the ANSWER IS 12/25.
The experimental probability of flipping a tail on the coin is:
P = 0.48
How to get the probability?
When we do an experiment N times, the probability of a given outcome is equal to the quotient between the number of times that the outcome of the experiment was the desired one, and the total number of times that we performed the experiment.
In this case, we want to find the probability of flipping a tail.
The experiment is performed 100 times.
48 of these times, the outcome is "tails".
So the experimental probability is:
P = 48/100 = 0.48

You need to remember the following:
1. The area of a rectangle can be calculated with the following formula:
[tex]A_r=lw[/tex]
Where "l" is the length and "w" is the width.
2. The area of a triangle can be calculated with the following formula:
[tex]A_t=\frac{bh}{2}[/tex]
Where "b" is the base and "h" is the height.
Use those formulas to find the area of each face.
Area of the rectangle
[tex]A_r=(10\ in)(4\ in)=40\ in^2[/tex]

A collection of 8 geodes has a mean weight of 14 ounces. A different collection of 12 geodes has a mean weight of 9 ounces. What is the mean weight of the 20 geodes? The mean weight is ounces.
Answer:
The mean weight of the 20 geodes is 11 ounce.
Step-by-step explanation:
Mean weight:
Mean weight is actually the average weight. Add up all weight, then divides by the number objects.
[tex]\textrm{Mean weight}=\frac{\textrm{Total weight}}{\textrm{Total number of objects}}[/tex]
Given that,
A collection of 8 geodes has mean weight of 14 ounce.
Then the total weight of 8 geodes is =(8×14) ounce
=112 ounce
A different collection of 12 geodes has a mean weight of 9 ounce.
Then the total weight of 8 geodes is =(12×9) ounce
=108 ounce
Therefore total weight of (12+8) =20 geodes is = (112+108) ounce
=220 ounce
The average mean of 20 geodes is
[tex]=\frac{220}{20}[/tex]
=11 ounce.
The mean weight of the 20 geodes is 11 ounce.
Answer: The mean weight of the 20 geodes is 11 ounce.
Mean weight means total weight divided by total number of objects.
Given that:
A collection of 8 geodes has mean weight of 14 ounce.
Then the total weight of 8 geodes is = (8×14) ounce = 112 ounce
A different collection of 12 geodes has a mean weight of 9 ounce.
Then the total weight of 8 geodes is = (12×9) ounce = 108 ounce
Therefore total weight of (12+8) =20 geodes is = (112+108) ounce =220 ounce
The average mean of 20 geodes is = [tex]\frac{220}{20}[/tex] =11 ounce.
Hence, the mean weight of the 20 geodes is 11 ounce.
