Complete question :

When Hiroto is writing, there is 0.92 probability that there will be no spelling mistakes on a page. One day, Hiroto writes an essay that is 11 pages long.

Assuming that Hiroto is equally likely to have a spelling mistake on each of the 11 pages, what is the probability that he will have a spelling mistake on at least one of the pages?

Answer:

0.60

Step-by-step explanation:

The question meets the requirement for a binomial probability distribution :

Recall:

P(x = x) = nCx * p^x * q^(n-x)

Given :

Probability of making a spelling mistake = 1 - p(not making) = 1 - 0.92 = 0.08

Hence,

p = 0.08 ; q = 0.92

n = 11

P(x ≥ 1) = 1 - p(x = 0)

P(x = 0) = 11C0 * 0.08^0 * 0.92^11

P(x = 0) = 1 * 1 * 0.3996373778857415671808

P(x = 0) = 0.399

P(x ≥ 1) = 1 - p(x = 0)

P(x ≥ 1) = 1 - 0.399

P(x ≥ 1) = 0.601

P(x ≥ 1) = 0.60

Chris is having custom t-shirts printed for a family reunion. The total cost of custom t-shirts, y, in dollars, for x t-shirts i
Nuetrik [128]

<u>Answer:</u>

C.  Each additional t-shirt being printed will increase the total cost by $11.

<u>Step-by-step explanation:</u>

We know that the total cost of custom t-shirts, y, in dollars, for x t-shirts is given by:

y = 11x + 25

Here 11 is the price of the shirt, x is the number of shirts that are printed and 25 might be some additional charges.

For each additional shirt that is printed, the total price, y, will increase by $11 so the correct answer option is C.

Using a trigonometric ratio to find a side length in a right triangle. ROUND TO THE NEAREST TENTH ‼️ Can someone help me please❓
SSSSS [86.1K]

Answer:

x ≈ 34.9

Step-by-step explanation:

Using the sine ratio in the right triangle

sin35° = \frac{opposite}{hypotenuse} = \frac{20}{x}

Multiply both sides by x

x × sin35° = 20 ( divide both sides by sin35° )

x= \frac{20}{sin35} ≈ 34.9 ( to the nearest tenth )

Simplify this expression<br> 5*sqrt(x^22) where x&lt;0
Doss [256]

Answer:

\boxed{5x^{11}, x < 0}

Step-by-step explanation:

5\sqrt{x^{22}}

Remember that we evaluate the term under the radical first.

Even though x < 0, x²² > 0

So,

5\sqrt{x^{22}} = 5x^{11}

The simplified expression is

\boxed{5x^{11}, x < 0}
