Answer:

4/7.

Step-by-step explanation:

This the question in which marbles have to be taken out of a bag. Odds in another word for probability.

Total number of marbles in the bag = 2 Blue + 1 Green + 4 Red = 7 marbles.

Required marbles = 3 red marbles.

Therefore:

P (a red marble is selected in the first attempt) = Red Marbles / Total Marbles.

P (a red marble is selected in the first attempt) = 4/7.

Therefore, the correct answer is 4/7!!!

Based on the survey, what is the probability that a person chosen at random is a diabetic patient or an eye patient

KonstantinChe [14]

First, you must find the total number of people. Add together 32, 54, 78, 112, and 96 to get 372. Next, add the number of diabetic patients with the number of patients with eye problems (54 + 112 = 166).

Your fraction is now 116/372. Simplify this to get your answer, 29/93 or 0.31.

Is 300 mm greater than 3 cm

rewona [7]

Answer:

Yes

Step-by-step explanation:

There are 10 mm in 1 cm.

We have 300 mm, so let's convert this to cm by using a proportion:

$\frac{10mm}{1cm} =\frac{300mm}{x}$ , where x is the number of cm in 300 mm.

Cross-multiplying, we get: 10x = 300, so x = 30 cm.

Clearly, 30 cm > 3 cm, so yes, 300 mm is greater than 3 cm.

Hope this helps!

Write the equations for 74,2 and 49

serious [3.7K]

Answer:

$x+10y=94$

Step-by-step explanation:

Assuming we want to find the equation (74,2) and (4,9)

This is an equation of a straight.

Let this equation be y=mx+b.

$m=\frac{9-2}{4-74} =-\frac{1}{10}$

We substitute the slope and (4,9) to get:

$y-9=-\frac{1}{10}(x-4)$

We rewrite in standard form to get:

$x+10y=94$
