Answer:

5) 350 girls

8) all but irrational, that is, {natural, whole, integer, rational}

Step-by-step explanation:

5) The total number of ratio units is 5+7=12. The total number of students is 600, so each ratio units stands for 600/12 = 50 students. Then the 7 ratio units that are girls stand for 7·50 = 350 girls.

8) √100 = 10, a natural number, whole number, integer, and rational number. Since it is rational, it is not irrational.

Ariana has a large piece of fabric that she wants to use to make some scarves. The number N of scarves she can make is inversely

AveGali [126]

Answer:

9 scarves.

Step-by-step explanation:

We have been given that the number N of scarves Ariana can make is inversely proportional to the area A of each scarf.

We know that equation of two inversely proportional quantities in in form $y=\frac{k}{x}$ , where, k is constant of variation and y is inversely proportional to x.

Let us find constant of variation using our given information.

$N=\frac{k}{A}$

$15=\frac{k}{3}$

$15*3=\frac{k}{3}*3$

$45=k$

Now, we will substitute $A=5\text{ and }k=45$ in our equation to solve for N.

$N=\frac{45}{5}$

$N=9$

Therefore, Ariana can make 9 scarves.

A policyholder has probability 0.7 of having no claims, 0.2 of having exactly one claim, and 0.1 of having exactly two claims. C

Sladkaya [172]

Answer:

0.89.

Step-by-step explanation:

So, we are given the following data or parameters or information which is going to aid in the solution to this question or problem. So, the data or parameters are;

(1). "probability 0.7 of having no claims, 0.2 of having exactly one claim, and 0.1 of having exactly two claims."

(2). " distributed on the interval [0,60] and are independent."

(3). "The insurer covers 100% of each claim."

So, taking (1) above we will have;

(Total probability= 0.7 + 0.2 + 0.1 = 0.1)

A = { (0.7 × 0)^2 + (0.2 × 1)^2 + ( 0.1 × 2)^2 =( 0.4) +( 0.4) = 0.8.

0.8 + total probability = 0.8 + 0.1 = 0.9.

So, from the question, we are to "Calculate the probability that the total beneﬁt paid to the policyholder is 48 or less."

Hence, P< 48/A = P < 48/0.9 = P < 53.33.

Thus, 53.33/60 = 0.89.

Guys plzzz help me i don't know how to figure out this question 10(6x+7)=26

Mekhanik [1.2K]

What is x
First you use distributive property
60x+70=26
Next subtract 70 on both sides which gives you -44
60x=-44
Then you divide 60 into -44 which will give you -1.36__36 is repeathing
so X=-1.36 repeading
