Assume that thermometer readings are normally distributed with a mean of degrees and a standard deviation of 1.00degrees C. A th

Andrew [12]

Answer:

0.2684 is the probability that the temperature reading is between 0.50 and 1.75.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 0 degrees

Standard Deviation, σ = 1 degrees

We are given that the distribution of thermometer readings is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(Between 0.50 degrees and 1.75 degrees)

$P(0.50 \leq x \leq 1.75)\\\\ = P(\displaystyle\frac{0.50 - 0}{1} \leq z \leq \displaystyle\frac{1.75-0}{1})\\\\ = P(0.50 \leq z \leq 1.75)\\= P(z \leq 1.75) - P(z < 0.50)\\= 0.9599 - 0.6915 = 0.2684 = 26.84\%$

0.2684 is the probability that the temperature reading is between 0.50 and 1.75.

Jennifer is saving money to buy a bike. The bike costs $223. She has "$128" saved, and each week she adds $19 to her savings.

castortr0y [4]

Answer: it would take her 5 weeks

You have to subtract 128 from 223 to find out how much money is left to earn. Which is 95. Then you must divide 95 divided by 19 because she get $19 each week and the answer is 5

The equation x2 – 1x – 90 = 0 has solutions {a, b}. What is a + b?

ololo11 [35]

It can be factorised as
$(x - 10)(x + 9)$
so the solutions are
x= 10 and x = -9

so the sum of the solutions is 10 -9 which is 1
