Assume that thermometer readings are normally distributed with a mean of 0 degrees C and a standard deviation of 1.00 degrees C.

A thermometer is randomly selected and tested. For the case below, draw a sketch, and find the probability of the reading. (The given values are in celsius degrees)
Between -1.42 and 1.61
The probability of getting a reading between -1.42 degrees C and 1.61 degreesC is_______ ( round to four decimal places as needed)

Answer:

The probability of getting a reading between -1.42 degree C and 1.61 degree C is 0.8685.

Step-by-step explanation:

We are given that

$Mean,\mu=0$ degree C

Standard deviation, $\sigma=1$ degree C

We have to find the probability of the reading between -1.42 and 1.61.

$P(-1.42$

$P(-1.42$

$P(-1.42$

Using the formula

$P(a$

$P(-1.42$

$P(-1.42$

Hence, the probability of getting a reading between -1.42 degree C and 1.61 degree C is 0.8685.

Use a truth table to verify the ﬁrst De Morgan law (p ∧ q)’ ≡ p’ ∨ q’.

Nutka1998 [239]

Answer:

(p ∧ q)’ ≡ p’ ∨ q’

Step-by-step explanation:

First, p and q have just four (4) possibilities, p∧q is true (t) when p and q are both t.

p ∧ q

t t t

t f f

f f t

f f f

next step is getting the opposite

(p∧q)'

<em>f</em>

<em> t</em>

<em> t</em>

<em> t</em>

Then we get p' V q', V is true (t) when the first or the second is true.

p' V q'

f <em>f</em> f

f <em>t</em> t

t <em>t</em> f

t <em>t</em> t

Let's compare them, ≡ is true if the first is equal to the second one.

(p∧q)' ≡ (p' V q')

<em>f f </em>

<em> t t</em>

<em> t t</em>

<em> t t</em>

Both are true, so

(p ∧ q)’ ≡ p’ ∨ q’

3 3/5 + 9 3/5 answer with a mixed number in simplest form

Romashka [77]

Both fractions have the same denominator so it's going to be easy. First set up your equation:

$3 \frac{3}{5} + 9 \frac{3}{5}$

Add the whole numbers:

$3 + 9 = 12$

Now add the fractions:

$\frac{3}{5} + \frac{3}{5} = \frac{6}{5}$

add both together:

$12 + \frac{6}{5} = 12 \frac{6}{5}$

$\frac{6}{5}$ is an improper fraction so change it:

$12 \frac{6}{5} = 13 \frac{1}{5}$

Since 6 is one more than 5, add 1 to the whole number and subtract the numerator and denominator(6 - 5 = 1) and make the remaining the new numerator. That leaves you with $13 \frac{1}{5}$

Your answer is $13 \frac{1}{5}$

Sheldon wants to buy a laptop that costs $ 450 from an electronics store . He has two coupons to choose from coupon A which give

Gekata [30.6K]

Answer:

Coupon B

Step-by-step explanation:

Given

$Price = \$450$

$Coupon\ A = \$80$

$Coupon\ B = 20.5\%$

Required

Which coupon is better

From the question, we have:

$Coupon\ A = \$80$

$Coupon\ B = 20.5\%$

Coupon B means that:

$Coupon\ B = 20.5\% * \$450$

$Coupon\ B = 0.205 * \$450$

$Coupon\ B = \$92.25$

By comparison:

Coupon B gives him a better buy because: $\$92.25 > \$80$
