Which table correctly shows all the sample spaces for tossing a coin and rolling an even number on a six-sided number cube?

wlad13 [49]

Alright, so you have to have heads and tails, as well as 3 spots each for each even number. Therefore, we need heads with 2 4 6 as well as tails with 2 4 6 (the third one down in the first picture)

Converting mixed numbers to impoper fractions

Oduvanchick [21]

To convert a mixed number to an improper, first, multiply the denominator of the fraction and the whole number of the fraction. Then, add the numerator to the product of the denominator and the whole number.
For example, 3 1/4. Multiply the 3 and 4 to get 12. Then add the one and you get 13. Lastly, take your sum (13 in this case) and put it over the original denominator (4) Your answer is 13/4. Hope that helps :)

Sugar canes have lengths X that are normally distributed with mean 365.45 cm and standard deviation 4.9 cm what is the probabili

Gemiola [76]

Answer:

The probability of the length of a randomly selected Cane being between 360 and 370 cm P(360 ≤X≤370) = 0.6851

Step-by-step explanation:

step(i):-

Let 'X' be the random Normal variable

mean of the Population = 365.45

Standard deviation of the population = 4.9 cm

Let X₁ = 360

$Z= \frac{x-mean}{S.D}= \frac{360-365.45}{4.9}$

Z₁ = -1.112

Let X₂ = 370

$Z= \frac{x-mean}{S.D}= \frac{370-365.45}{4.9}$

Z₂ = 0.911

Step(ii):-

The probability of the length of a randomly selected Cane being between 360 and 370 cm

P(x₁≤x≤x₂) = P(z₁≤Z≤z₂)

P(360 ≤X≤370) = P(-1.11≤Z≤0.911)

= P(Z≤0.911)-P(Z≤-1.11)

= 0.5 +A(0.911) - (0.5-A(1.11)

= 0.5 +A(0.911) - 0.5+A(1.11)

= A(0.911) + A(1.11)

= 0.3186 + 0.3665

= 0.6851

The probability of the length of a randomly selected Cane being between 360 and 370 cm P(360 ≤X≤370) = 0.6851
