Answer:

40

Step-by-step explanation:

There is enough information, so D is not an answer.

10 is far to low. The number is roughly 40. So A is not the answer.

16/20 = .80 that recommended the tooth paste. If you stopped there, 40 would be your answer.  But they took one more survey.

24/30 = .80

So both groups come back with an amount that = 0.8

That means that you should pick 40 as your answer.

Lakima has a spinner divided into 5 equal sections that are labeled 1 though 5. She wants to compare the theoretical probability
Scrat [10]

Using probability concepts, it is found that:

  • The theoretical probability of spinning an odd number is equal to 3/5 = 0.6.
  • The experimental probability of spinning an odd number is equal to 1/2 = 0.5.
  • Therefore, the theoretical probability of spinning an odd number is greater than the experimental probability of spinning an odd number.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

A theoretical probability is calculated without considering experiments, and we have that 3 out of the 5 numbers(1,3,5) and are odd, hence the theoretical probability is given by:

pT = 3/5 = 0.6.

For an experimental probability, we consider the experiments. Of the 6 spins, 3 resulted in an odd number, hence the experimental probability is given by:

p = 3/6 = 1/2 = 0.5.

Therefore, the theoretical probability of spinning an odd number is greater than the experimental probability of spinning an odd number.

Patrick is constructing the circumscribed circle for △RST. Which construction could be his first step?
Naya [18.7K]
Steps in constructing a circumscribed circle on a triangle using a just a compass and a straight edge.
1) construct a perpendicular bisector of one side of ΔRST.
2) construct another perpendicular bisector of another side of ΔRST
3) the point where the two bisectors intersect will be the center of the circle.
4) place the compass on the center point, adjust its length to ensure that any corner of the triangle will be reached and draw the circumscribed circle.

Rectangle 1 has length 10 and width 20. Rectangle 2 is made by multiplying each dimension of Rectangle 1 by a factor of k=3
Gwar [14]

Answer:

30cm, 60cm

Step-by-step explanation:

Given data

Dimensions of the first rectangle

Length =10cm

Width =20cm

We are told that the dimensions of the second rectangle is gotten by multiplying the first rectangle by 3

Hence the dimensions of the second rectangle is

Length =10*3= 30cm

Width = 20*3= 60cm
