Answer:
$23.42
Step-by-step explanation:
zoey's bill= .5x+5
logan's bill= x
.5x+5+x=60.26
1.5x+5=60.26
1.5x=55.26
x=36.84
.5(36.84)+5= 23.42
Answer:
It would take Abigail six days to read 32,400 words of a book if she were to read 30 minutes per day.
Step-by-step explanation:
If Abigail reads 180 words per minute, and she reads 30 minutes per day, we need to multiply 180 by 30 to figure out how many words she reads per day.
180 × 30 = 5,400
Abigail reads 5,400 words per day.
Then, we divide 32,400 by 5,400 to figure out how many days it would take Abigail to read 32,400 words.
32,400 ÷ 5,400 = 6
It would take Abigail six days to read 32,400 days.
Hope that helped!
The solution would be like this for this specific problem:
Given:
No
(Did Not Lie) Yes (Lied)
Positive Test Result 10 29
(Positive test indicated that the subject lied.) (false positive) (true positive)
Negative test result 66 18
(Polygraph test indicated that the subject did not lie.) (true negative) (false negative)
Find:
The
probability that all four test subjects had a true negative test result when
they are randomly selected without replacement.
Formula:
(66/123) x (65/122) x (64/121) x (63/120) = 0.0793864272
Therefore, when they are randomly selected without
replacement, the <span>probability that all four test subjects had a
true negative test result is 0.079</span>.
Answer: 30
Step-by-step explanation:
Simple formula is
LCM*GCF=PRODUCT OF 2 NUMBERS
120 * 10 = 40 * x
1200 = 40x
x = 1200/40
x = 30
