Answer:

She should expect to draw 60 red hats.

Step-by-step explanation:

Explanation

This must assume that after each draw,  she replaces the hat she drew, otherwise you'd never get to the hundredth draw.

The total number of choices Tyler has is 5. She can draw one of 3 red hats and 1 of 2 blue hats.

The probability of drawing a red hat is 3 in 5

Though you don't need it, the probability of drawing a blue hat is 2/5

Solution

The total number of successful draws = fraction of reds * number of reds

Number red = 3/5 * 100 = 60

Answer

She should draw roughly 60 red hats.

Please help me solve for x
kkurt [141]

\qquad \qquad\huge \underline{\boxed{\sf Answer}}

The shown pair of angles are Co interior angle pair, therefore the sum of those angles is 180°

\qquad \sf  \dashrightarrow \: 130 \degree + 7x + 1 \degree = 180 \degree

\qquad \sf  \dashrightarrow \: 131 \degree + 7x = 180 \degree

\qquad \sf  \dashrightarrow \:  7x= 180 \degree - 131 \degree

\qquad \sf  \dashrightarrow \:  7x= 49 \degree

\qquad \sf  \dashrightarrow \:  x=49 \degree \div 7

\qquad \sf  \dashrightarrow \:  x=7 \degree

The required value of x is 7°

A field is a rectangle with a perimeter of 1220 feet. The length is 100 feet more than the width. Find the width and length of t
rosijanka [135]
To start, let x represent the width and x+100 represent the length. Since the perimeter of a figure is the sum of all the measurements of the side which can be represented by (x+100)+(x+100)+x+x and since you know your perimeter is 1220, you can set the expression equal to 1220. This would look like this:
(x+100)+(x+100)+x+x=1220

Once you have done that, combine any like terms (combine terms with the same variables and raised to the same power together) which would simplify to this:
4x+200=1220

Now that you have your like terms simplified, subtract 200 from both sides to get 4x=1020 and finally, to solve for x, or find the width, divide both sides by 4 to get x=255.

Now that you have your width, now you must find your length as the question asks to find the dimensions of the rectangular field. To find the length, add 100 to the width, 255 since according to the information given, the length is 100 more than the width. When you add 100 to 255, you should get that your length is 355. 

Now that you have your length and width, you can conclude that the dimensions of the field is 255 by 355 feet, which is your answer :)

Drug X is to be administered intravenously at a dosage of 20 mg/kg. A patient weighing 60 kg should receive
arsen [322]

Answer:

D. 1200 mg

Step-by-step explanation:

In order to find the solution we need to understand that a dosage of 20 mg/kg means that 20 mg are administered to the patient for each kg of his/her weight.

So, if the patient weight is 60 kg then:

Total drug X = (20mg/Kg)*(60Kg)=1200mg.

In conclusion, 1200 mg will be administered to the patient, so the answer is D.
