Answer:

Range of Relation is ,set of all Second elements of an Ordered Pair.

  For, a Set of Ordered Pair represented in terms of  (a,b)

→Set of all (First Element =a) is called Domain of the relation.

→Set of all (Second Element =b) is called Range of the relation.

Dave is a builder. Yesterday he made mortar mix. He used 24kg of sand and 5kg of cement. Today he needs to make the same type of
polet [3.4K]

Answer:

7.5 kg

Step-by-step explanation:

Ratio of sand to cement = 24kg : 5kg

Today he needs to make the same type of mortar mix, but he will use 36kg of sand.

Let

x = quantity of cement used

Ratio of sand to cement = 36 kg : x kg

Equate both ratios

24 kg : 5 kg = 36 kg : x kg

24/5 = 36/x

Cross product

24 * x = 5 * 36

24x = 180

x = 180/24

x = 7.5

x = quantity of cement used = 7.5 kg

Out of 200 people sampled, 52 had kids. Based on this, construct a 99% confidence interval for the true population proportion of
iragen [17]

Answer:

0.180144 < p < 0.339856

Step-by-step explanation:

According to the Question,

  • Given That, Out of 200 people sampled, 52 had kids, Thus the proportion of the mean is 52/200 = 0.26

⇒ standard error of the sample is square root(0.26 * (1-0.26) / 200) = 0.031

⇒alpha(a) = 1 - 99/100 = 0.01

⇒critical probability(p*) = 1 - a/2 = 0.995

⇒assuming a normal distribution, look for the z-score associated with 0.995 cumulative probability , z-score = 2.576

⇒margin of error(ME) = 2.576 * 0.031 = 0.079856

  • the confidence interval is 0.26 + or - 0.079856

0.180144 < p < 0.339856

Help appreciated !!!!
sergiy2304 [10]

Answer:

Step-by-step explanation:

The circle is divided into 5 sections. The probability that the needle lands on a particular color is equally likely.

   So,

        P(red) = \frac{1}{5}\\\\P(green) = \frac{1}{5}\\\\

   Probability of not blue = 1 - Probability of blue

                                      = 1 - P(blue)\\\\=1 - \frac{1}{5}\\\\= \frac{4}{5}
