Answer:

m∠Y = 40°

Step-by-step explanation:

The sum of complementary angles is 90°. If we let s and y represent m∠S and m∠Y, respectively, the angle measures in degrees satisfy ...

s + y = 90

(4y -110) +y = 90 . . . . . . . . substitute for s

5y = 200 . . . . . . . . . add 110

y = 40 . . . . . . . divide by 5

The measure of angle Y is 40°.

An industry representative claims that 10 percent of all satellite dish owners subscribe to at least one premium movie channel.

Greeley [361]

Answer: 1) 0.6561 2) 0.0037

Step-by-step explanation:

We use Binomial distribution here , where the probability of getting x success in n trials is given by :-

$P(X=x)=^nC_xp^x(1-p)^{n-x}$

, where p =Probability of getting success in each trial.

As per given , we have

The probability that any satellite dish owners subscribe to at least one premium movie channel. : p=0.10

Sample size : n= 4

Let x denotes the number of dish owners in the sample subscribes to at least one premium movie channel.

1) The probability that none of the dish owners in the sample subscribes to at least one premium movie channel = $P(X=0)=^4C_0(0.10)^0(1-0.10)^{4}$

$=(1)(0.90)^4=0.6561$

∴ The probability that none of the dish owners in the sample subscribes to at least one premium movie channel is 0.6561.

2) The probability that more than two dish owners in the sample subscribe to at least one premium movie channel.

= $P(X>2)=1-P(X\leq2)\\\\=1-[P(X=0)+P(X=1)+P(X=2)]\\\\= 1-[0.6561+^4C_1(0.10)^1(0.90)^{3}+^4C_2(0.10)^2(0.90)^{2}]\\\\=1-[0.6561+(4)(0.0729)+\dfrac{4!}{2!2!}(0.0081)]\\\\=1-[0.6561+0.2916+0.0486]\\\\=1-0.9963=0.0037$

∴ The probability that more than two dish owners in the sample subscribe to at least one premium movie channel is 0.0037.

A 35% dextrous solution (35 mg per 100 mL of solution) is given intravenously. Suppose a total of 1.17 L of the solution is give

ludmilkaskok [199]

Answer:

The flow rate in dextrous solution is 0.117 litres per hour

Step-by-step explanation:

Given:

The volume of fluid which passes per unit time = 1.17 Litres

Time Period = 10 hour

To Find:

The Flow rate per hour = ?

Solution:

Flow rate is defined as rate at which the "{volume of fluid which passes per unit time"

Here the Flow rate is = $\frac{\text{volume of fluid which passes per unit time}}{ time period}$

On substituting the values

The Flow rate is = $\frac{1.17}{10}$

The flow rate is 0.117 litres per hour

Thus 0.117 litres of dextrous solution flows per hour.

Chris used 43.96 feet of fencing to enclose a circular garden. What is the radius, in feet, of the garden?

UNO [17]

Answer:

r = 7 ft

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

Here C = 43.96 , then

2πr = 43.96 ( divide both sides by 2 × 3.14 ← for π )

r = $\frac{43.96}{2(3.14)}$ = $\frac{43.96}{6.28}$ = 7 ft
