please show work!
Answer:
k=2 or 5/4
Step-by-step explanation:
8k^2-26k+20=0
2(4k²-13k+10)=0
(4k²-13k+10)=0/2
4k²-8k-5k+10=0
4k(k-2)-5(k-2)=0
(k-2)(4k-5)=0
either.
k=2
or

Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns (x) and $8 per hour babysitting (y). And she wants to earn at least $160 per week. Rewrite the inequality from in slope-intercept form
Answer:
18x ≥ 160
Step-by-step explanation:
Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns (x) and $8 per hour babysitting (y). And she wants to earn at least $160 per week.
Let the number of hours = x
At least = Greater than or equal to
Slope intercept form
= y = mx + c
y = $160
Hence
10x + 8x ≥ 160
18x ≥ 160

A set of magical wand prices are normally distributed with a mean of 50 dollars and a standard deviation of 4 dollars. A blackthorn wand has a price of 45.20
Complete Question
A set of magical wand prices are normally distributed with a mean of 50 dollars and a standard deviation of 4 dollars. A blackthorn wand has a price of 45.20. What proportion of wand prices are lower than the price of the blackthorn wand? You may round your answer to four decimal places
Answer:
0.1151
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = $45.20
μ is the population mean = $50
σ is the population standard deviation = $4
We are solving for x < 45.20
Hence:
z = 45.20 - 50/4
z = -1.2
Probability value from Z-Table:
P(x<45.20) = 0.11507
Approximately to 4 decimal places = 0.1151
Therefore, the proportion of wand prices that are lower than the price of the blackthorn wand is 0.1151

HOPE THIS HELPS!!20 divided by 2 1/3 = 8.57
8 batches is the answer.
Answer:
Actually, 20 divided by 2 1/3 equals 8.57 repeating (8.571428...), which can be rounded to 8.57 to two decimal places.
To see why, we can convert the mixed number 2 1/3 to an improper fraction:
2 1/3 = (2 * 3 + 1) / 3 = 7/3
Then, we can rewrite the division as a fraction and simplify:
20 / (7/3) = 20 * (3/7) = 60/7 = 8.571428...
So, 20 divided by 2 1/3 is approximately 8.57.

If 3 runners has a mean running time of 6.2, 7.4 and.6.9 and had an interquartile range of 1.1, .02 and .08 who would be the fastest runner
Answer:
The runner with a mean running time of 6.2
Step-by-step explanation:
The value range parameters of the three runners are;
The mean running time of the runner, A = 6.2
The mean running time of the runner, B = 7.4
The mean running time of the runner, C = 6.9
The interquartile range of the runner, A = 1.1
The interquartile range of the runner, B = 0.02
The interquartile range of the runner, C = 0.08
Whereby the number of running times for the 3 runners is large, and with the assumption that distribution of the mean is normal, we have
The mean = The mode of the data
Therefore, the minimum, and maximum running time of the runners are;
Runner A;
Minimum running time = 6.2 - 1.1 = 5.1
Maximum running time = 6.2 + 1.1 = 7.3
Runner B;
Minimum running time = 7.4 - 0.02 = 7.38
Maximum running time = 7.4 + 0.02 = 7.42
Runner C;
Minimum running time = 6.9 - 0.08 = 6.82
Maximum running time = 6.9 + 0.08 = 6.98
The fastest runner has the lowest running time;
Therefore, the fastest runner is runner A with a mean running time of 6.2 with a minimum running time of 5.1
