Answer:
x - 14 < 25
Step-by-step explanation:
You solve this by replacing the words with the number, letter or symbol they equal. So a number is x and decreased is subtraction. So far you have, x - 14. Then you look at less than and you know that the less than symbol is < so you plug that in and then you put 25 on the end.
The answer should be 123/500
First you have to create a proportion which would look like 25/100 =n/136. to find the answer cross multiply the answer: 100n=25*136 which simplified is: 100n=3400. Now you have to divide by 100 to either side:100n/100=3400/100 and that simplified is n=34 and 34 dollars is your answer
Answer: P(x > - 0.23) = 0.41
Step-by-step explanation:
Since we are assuming that the readings at freezing on a batch of thermometers are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = the readings at freezing on a batch of thermometers.
µ = mean temperature reading
σ = standard deviation
From the information given,
µ = 0°C
σ = 1.00°C
the probability of obtaining a reading less than -0.23°C is expressed as
P(x > - 0.23)
For x = - 0.23
z = (- 0.23 - 0)/1 = - 0.23
Looking at the normal distribution table, the probability corresponding to the z score is 0.41
I think if you take 360 and divide it by 55 thats how many busses they used. Then take that answer and divide it by 13 to find how many vans were used.
