Answer:
She rode [tex]1\frac{1}{2}[/tex] miles from her friends house to school.
Step-by-step explanation:
Geneva rode her bike a total = [tex]2\frac{1}{2}[/tex] miles
She rode from her house to the park = [tex]\frac{4}{5}[/tex] miles
She rode from the park to her friend's house = [tex]\frac{1}{5}[/tex] miles
total distance from her house to her friend's house = [tex]\frac{4}{5}+\frac{1}{5}[/tex] = 1 mile
Finally she rode the rest of the way to her school.
distance between her friend's house to school = [tex]2\frac{1}{2}-1[/tex] = [tex]\frac{3}{2}[/tex] miles
[tex]1\frac{1}{2}[/tex] miles she rode from her friends house to school
This is a square pyramid. What is the length of the base? h=3 v=36
volume of square pyramid = S^2*h/3
volume = 36
h = 3
36 = S^2 *3/3
36 = S^2
S = sqrt(36)
S = 6
length of base = 6
if the coefficient of determination for a data set is 0.25 and the SSE for the data set is 24, what is the SST for the data set?
Answer: SST for the data set is 32.
Step-by-step explanation:
Since we have given that
Coefficient of determination = R² = 0.25
Value of SSE = 24
We need to find SST.
As we know the formula for "Coefficient of determination":
[tex]R^2=1-\dfrac{SSE}{SST}[/tex]
We will put the above mentioned value:
[tex]0.25=1-\dfrac{24}{SST}\\\\0.25-1=-\dfrac{24}{SST}\\\\-0.75=-\dfrac{24}{SST}\\\\SST=\dfrac{24}{0.75}\\\\SST=32[/tex]
Hence, SST for the data set is 32.
can 0.91919191 be written as a fraction?
Final answer:
Yes, 0.91919191 can be written as a fraction. The fraction form is 91919191/9999999.
Explanation:
Yes, 0.91919191 can be written as a fraction. To convert a repeating decimal to a fraction, we can use the following steps:
Let x be the repeating decimal.Multiply both sides of the equation x = 0.91919191... by a power of 10 that moves the decimal point to the right of the repeating part (8 digits in this case): 10000000x = 91919191.91919191...Subtract the original equation (x) from the new equation (10000000x) to eliminate the repeating part: 10000000x - x = 91919191.91919191... - 0.91919191...Simplify the equation: 9999999x = 91919191Divide both sides of the equation by 9999999 to solve for x: x = 91919191/9999999Therefore, 0.91919191 can be written as the fraction 91919191/9999999.
Y=(3/5)x -3 and 5y =3x-10 these lines are and the second question?
The given lines Y=(3/5)x -3 and 5y =3x-10 are examples of linear equations which, when solved, are found to be parallel due to their identical slope.
Explanation:The lines given in the question are in the format y = mx + b, where 'm' is the slope and 'b' is the y-intercept. The equations are Y=(3/5)x -3 and 5y =3x-10. By comparing the coefficients, the slope of the first line is 3/5 and the y-intercept is -3. For the second equation, we first need to convert it into the 'y = mx + b' form. Dividing every term by 5 gives us y = (3/5)x - 2. Therefore, the slope of the second line is also 3/5 and the y-intercept is -2. Since both lines have the same slope, they are parallel lines.

What function is represented below? graph begins in the first quadrant and decreases quickly while crossing the ordered pair 2, 1. Then the graph begins to decrease slowly as it approaches the x axis. f(x) = one fourth to the power of x plus 2 f(x) = one fourth to the power of x + 2 f(x) = one fourth to the power of x minus 2 f(x) = one fourth to the power of x − 2
Answer:
The represented function is :
[tex]f(x)=(\frac{1}{4})^{x-2}[/tex]
Step-by-step explanation:
[tex]1.\thinspace f(x)=(\frac{1}{4})^x +2[/tex]
And the equation must pass through (2,1) as given,
But, f(2) = 2.0625 ≠ 1 so this is not the required function.
[tex]2.\thinspace f(x)=(\frac{1}{4})^{x+2}[/tex]
And the equation must pass through (2,1) as given,
But, f(2) = 0.0039 ≠ 1 so this is not the required function.

On a survey mission,a pilot flew out to a parcel of land and back in 7h. The rate flying out was 120mph. The rate flying back was 90mph.how far away was the parcel of
To find the distance, multiply the speed by the time for each leg of the trip and add them together to get the total distance of 735 miles.
Explanation:To find the distance to the parcel of land, we can use the formula Distance = Speed x Time. Since the pilot flew out and back, we can calculate the distance for each leg of the trip and then add them together.
Distance going out = Speed x Time = 120 mph x (7/2) hours = 420 miles
Distance coming back = Speed x Time = 90 mph x (7/2) hours = 315 miles
Total distance = Distance going out + Distance coming back = 420 miles + 315 miles = 735 miles

Let x be the number of successes throughout n independent repetitions of a random experiment having probability of success p=1/4. determine the smallest value of n so that p(1<=x)>=0.7
To answer problems like this you have to use binomial:
P (x > 1) = 1 – p (0 < x < 1) > .7
So:
1 – p (0) – p (1) > .7
1 – (3/ 4) ^n – (3/ 4) ^n (n – 1 ) (1/ 4) > .7
Therefore n > 5.185, and the smallest value of n so that we can satisfy the given condition is 6 (rounded up)

Derrick’s parents are finalizing a budget for his college expenses. His first year of college will cost $8,000, and his expenses will increase by 12% each year. What is the amount they should budget for Derrick’s four-year college education, to the nearest dollar?
$38,235 is needed.
$42,823 is needed.
$32,072 is needed.
$39,200 is needed.
1st year = 8000
2nd year = 8000 * 1.12 = 8960
3rd year = 8960*1.12 = 10035.20
4th year = 10035.20 * 1.12 = 11239.42
8000 + 8960 + 10035.20 + 11239.42 = 38234.62 round to $38,235
Answer:
$38,235 is needed.
Step-by-step explanation:
Given,
The cost of first year of college is $ 8000 and it is increasing by 12 % each year,
So, His first year's cost = $ 8000,
Second year's cost = 12 % more than the first year's cost = 112 % of first year's cost = 112 % of 8000 = 1.12 × 8000 = $ 8960,
Third year's cost = 112 % of second year's cost = 112 % of 8960 = 1.12 × 8960 = $ 10035.2
Fourth year's cost = 112% of third year's cost = 1.12 × 10035.2 = $ 11239.424
Hence, Total cost for four-year college education = 8000 + 8960 + 10035.2 + 11239.424 = $ 38234.624 ≈ $ 38235
⇒ $38,235 is needed.

choose the ratio that you would use to convert 5.5 pounds to ounces
Answer:
A. 16 ounces/1 pound
Step-by-step explanation:
Remember that: 1 pound (lb) is equal to 16 Ounces (oz).
Then you have to find a ratio to convert 5.5 pounds to ounces.
If you write: 5.5 pounds, you have to find a ratio that eliminates pounds in order to get ounces:
5.5 pounds*16 ounces/1 pound
In this way pounds in the numerator is eliminated with pounds from the denominator and the result you get is in units of ounces.
5.5 pounds*16 ounces/1 pound=88 ounces
