She has 1 61/152 pounds of apples left
How to determine how many pounds of apples she has left?Fractions are represented as numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing
In order to find how many pounds of apples she has left, subtract the apple she sold from the apple she begins with. That is:
Apple left = 35 1/2 - (35 1/2 * 1/2) - (35 1/2 *4/19) - (35 1/2 * 1/4 )
Apple left = 1 61/152

wat factor of 26 is between 4 and 26
Answer:
13
Step-by-step explanation:
cos 13 x 2 = 26
13 is a factor that is more than 4 and less then 26
The factor of the number 26 that is between 4 and 26 is 13. Factors are the numbers that can divide into a number without leaving a remainder. In this case, the factors of 26 are 1, 2, 13, and 26.
Explanation:In mathematics, a factor of a number is a number that divides into another number without leaving a remainder. In the case of the number 26, its factors include 1, 2, 13, and 26. The factor of 26 that is between 4 and 26 is 13.
To find this, you can go through the factors of 26 one by one. The factors are found by dividing 26 by all the numbers up to 26, and the numbers that give a remainder of 0 are the factors. In this case, 1, 2, 13, and 26 divide evenly into 26, and so are the factors of 26. Of these, only 13 lies between 4 and 26.

The average lifetime of smoke detectors that a company manufactures is 5 years, or 60 months, and the standard deviation is 8 months. Find the probability that
sample of 29 smoke detectors will have a mean lifetime
between 57 and 64 months. Assume that the sample is taken from a large population and the correction factor can be ignored.
Round the final answer to at least four decimal places and intermediate z-value calculations to two decimal places.
The required probability is 0.8945 that a sample of 29 smoke detectors will have a mean lifetime between 57 and 64 months.
To find the probability that a sample mean is between 57 and 64 months, we need to find the standard deviation of the sample mean, which is given by the standard deviation of the population divided by the square root of the sample size.
The standard deviation of the sample mean = standard deviation of the population / square root of sample size = 8 / √(29) = 8 / 5.385 = 1.48
Next, we need to standardize the interval of 57-64 months by subtracting the mean and dividing it by the standard deviation of the sample mean.
z₁ = (57 - 60) / 1.48 = -2.03
z₂ = (64 - 60) / 1.48 = 1.35
Finally, we can use a standard normal table to find the area under the normal curve between z₁ and z₂, which gives us the probability of a sample mean falling in the interval (57, 64).
P(57 < X < 64) = P(-2.03 < Z < 1.35) = 0.9790 - 0.0845 = 0.8945
Therefore, the final answer is 0.8945, rounded to four decimal places.

Write an equation for the following points. (1, 100) (2, 50) (4, 25), (5, 20)
The equation of line is y = -50x + 150
What is Slope?
A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Points:(1, 100) (2, 50) (4, 25), (5, 20)
so, the slope is
= (50-100)/ (2-1)
= -50 /1
= -50
using slope intercept form
y - 100 = m (x- 1)
y- 100 = -50(x-1)
y- 100 = -50x + 50
y = -50x + 50 + 100
y = -50x + 150
Hence, the equation of line is y = -50x + 150.

What is the Sum of the Xm'f Coulumn
To find the sum of the Xm'f column, we first need to calculate the midpoint (Xm) for each class interval and then multiply it by the frequency (f) for that interval. The midpoint of each class interval can be calculated as the average of the lower and upper bounds of the interval.
For the first class interval 50-52:
Xm = (50 + 52) / 2 = 51
Xm'f = Xm * f = 51 * 5 = 255
For the second class interval 53-55:
Xm = (53 + 55) / 2 = 54
Xm'f = Xm * f = 54 * 8 = 432
For the third class interval 56-58:
Xm = (56 + 58) / 2 = 57
Xm'f = Xm * f = 57 * 12 = 684
For the fourth class interval 59-61:
Xm = (59 + 61) / 2 = 60
Xm'f = Xm * f = 60 * 13 = 780
For the fifth class interval 62-64:
Xm = (62 + 64) / 2 = 63
Xm'f = Xm * f = 63 * 11 = 693
Finally, we can add up the Xm'f values for each interval to get the sum of the Xm'f column:
Sum of Xm'f = 255 + 432 + 684 + 780 + 693 = 2954
So the sum of the Xm'f column is 2954.
1. You have the digits 0-9. How many 6-digit permutations are odd and do not start with 0
Answer:
We have 10 digits to choose from (0-9), so the total number of 6-digit permutations is 10 × 10 × 10 × 10 × 10 × 10 = 1,000,000.
Of these, the permutations that start with 0 can be eliminated, leaving 9 × 9 × 9 × 9 × 9 × 9 = 729,000.
Now, we need to figure out how many of these are odd. To do this, we note that odd numbers end in 1, 3, 5, 7, or 9. This means that the last digit of an odd 6-digit permutation is always one of these five digits. Since we are choosing the last digit from 5 options, there are 5 × 729,000 = 3,645,000 odd 6-digit permutations that do not start with 0.

Pat and Rich drove to the beach
last weekend. It took them twice as
long to get back as it did to drive
there. If they spent 9 hours traveling
to and from the beach, how long
did it take them to drive each way?
The total time that it took Pat and Rich to get to the beach is given as 3 hours.
How to solve for the total timeLet's call the time it took Pat and Rich to drive to the beach "t".
Since it took them twice as long to get back, it took them 2t to get back.
The total time they spent traveling was 9 hours, so we can set up an equation:
t + 2t = 9
Combining like terms:
3t = 9
Finally, dividing both sides by 3:
t = 3
So it took them 3 hours to drive to the beach, and 6 hours to drive back.
