Answer:

74%->91.22

100%-> 123.27(estimated)

The total amount of the utility bill will be $123.2.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that on a recent utility bill, the water/sewer/garbage portion of the bill was $91.22. This consisted of 74% of the total bill.

The total amount will be calculated as below:-

74% ⇒ $91.22

1% ⇒ 91.22 / 74

100% ⇒ ( 91.22 x 100 ) / 74

100% ⇒ $123.27

Therefore, the total amount of the utility bill will be $123.2.

Step-by-step explanation:

Answer:

1. m<2 = 115 °

2. m<5 = 83 °

3. m<8 = 45 °

4. m<4 = 137 °

Step-by-step explanation:

1. Determination of m<2

m<1 = 115 °

m<2 =?

m<2 = m<1 (vertically opposite angles are equal)

m<2 = m<1

m<2 = 115 °

2. Determination of m<5

m<6 = 83 °

m<5 =?

m<5 = m<6 (vertically opposite angles are equal)

m<5 = m<6

m<5 = 83 °

3. Determination of m<8

m<9 = 45 °

m<8 =?

m<8 = m<9 (vertically opposite angles are equal)

m<8 = m<9

m<8 = 45 °

4. Determination of m<4

m<3 = 137 °

m<4 =?

m<4 = m<3 (vertically opposite angles are equal)

m<4 = m<3

m<4 = 137 °

===========================================================

Explanation:

1/3 converts to the decimal form 0.333333... where the 3's go on forever

5/3 is a similar story but 5/3 = 1.666666.... where the '6's go on forever

The notation [tex]0.\overline{6}[/tex] indicates that the 6's go on forever.

So, [tex]0.\overline{6} = 0.666666\ldots[/tex]

The horizontal bar tells us which digits repeat. As another example, [tex]0.\overline{123} = 0.123123123123\ldots[/tex]

The three dots just mean "keep this pattern going forever".

----------

Everything mentioned so far has the decimal portions go on forever repeating some pattern over and over.

The only one that doesn't do this is 33% which converts to the decimal form 0.33

The value 0.33 is considered a terminating decimal since "terminate" means "stop". So this is the value that doesn't fit in with the other three items mentioned.

Answer:

The drug have effect on lowering the cholesterol.

Step-by-step explanation:

H₀ : μ₁ - μ₂ = 0

⇒ H₀ : μ₁ =  μ₂

H₁ : μ₁ - μ₂ < 0

⇒H₁ : μ₁ <  μ₂

Now,

given , n₁ = 23 , n₂ = 23

∴ Degree of freedom = v = n₁ + n₂ - 2

                                         = 23 + 23 - 2 = 44

⇒v = 44

Now,

Given, level of significance = 5% = 0.05

For the given significance level, critical time t = 1.68

As

Decision rule states that'if t < 1.68 , reject H₀

Now,

For Drug:

mean = m₁ = 195

SD = d₁ = 35

People = n₁ = 23

For placebo :

mean = m₂ = 245

SD = d₂ = 31

People = n₂ = 23

Now,

Variance = [tex]\frac{(23-1)35^{2} + (23-1)31^{2} }{23 + 23 - 2}[/tex]  = 1093

Standard Deviation, S = 33.06

Point estimate = m₁ - m₂ = 195 - 245 = -50

Standard deviation error = S×([tex]\frac{1}{n_{1} } + \frac{1}{n_{2} }[/tex] ) = 9.75

Now,

Test statistics = [tex]-\frac{50}{\sqrt{9.75} } = -5.13[/tex]

⇒ t < 6.13

⇒Reject H₀

⇒The drug have effect on lowering the cholesterol.

The length of QR to the nearest tenth of a foot is 287.28 feet.

Step-by-step explanation:

Let a right angled Triangle QRS have base SQ, perpendicular RS and Hypotenuse QR.

∠S = 90°

∠Q = 17°

Perpendicular = 84 ft

We know that for a right angle triangle

SinΘ = perpendicular/Hypotenuse

Sin ∠Q = 84/QR

QR = 84/sin(17°)

QR = 84/0.2924

QR = 287.2777

QR = 287.28 feet

The cosine rule is used to determine the length of side q. Then the length of side q is 5.34 inches.

Trigonometry deals with the relationship between the sides and angles of a triangle.

In ΔQRS, r = 5.1 inches, s = 2.4 inches and ∠Q=26°.

Then the length of q will be given by the cosine rule.

[tex]\rm q = \sqrt{r^2 + s^2 - 2rs \cos Q}\\\\q = \sqrt{5.1^2 + 2.4^2 - 2 \times 5.1 \times 2.4 \cos 26^o}\\\\q = \sqrt{26.01 + 5.76 - 24.48 \times 0.89879}\\\\q = \sqrt{50.49 - 22}\\\\q = \sqrt{28.49}\\\\q = 5.34 \ inches[/tex]

The length of the q is 5.34 inches.
