(b) (7.5 x 10^5) - (8.6 x 10^4) + (2.7 x 10^3) +(1.4 x 10^4)​

Answer:

P(A, B or C) = 6/7 or 0.8571

Step-by-step explanation:

From the image, we have the frequency for each grade as;

Grade A = 5

Grade B = 10

Grade C = 15

Grade D = 3

Grade F = 2

We want to find the probability that a student earns a grade of A, B or C.

Total frequency for A, B & C = 5 + 10 + 15 = 30

There are a total of 35 students overall for the geometry course.

Thus;

P(A, B or C) = 30/35

P(A, B or C) = 6/7 or 0.8571

Answer:

Step-by-step explanation:

Total frequency for A, B & C = 5 + 10 + 15 = 30

There are a total of 35 students overall for the geometry course.

P(A, B or C) = 30/35

P(A, B or C) = 6/7 or 0.8571

now we round to the hundredths place

0.8571 ⇒ 0.86

3.865in^2

It's (the area of the square minus the area of the circle) divided by 2.

So, Area of the square is 6x6=36

Area of the circle is (pi)*(radius=3)^2=28.27

36-28.27=7.73

7.73/2=3.865in^2

3.51% probability that this fund-raising event is a success

Step-by-step explanation:

In a set with mean  and standard deviation , the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

meiko has 32 pencils

Step-by-step explanation:

8×4=32

Meiko has 32 pencils.

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, Mieko has 4 times as many pencils as Holden. Holden has 8 pencils.

Let Mieko has x pencils,

Establishing the equation,

Therefore, according to question,

x = 4 × 8

Answer:

The distance between the points

d = LM = 10.24

Step-by-step explanation:

Step(i):-

Given that the points are L ( 7,-1) and M (-2,4)

The distance formula

  LM = [tex]\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1} )^{2} }[/tex]

Step(ii):-

[tex]LM= \sqrt{(-2-7)^{2} +(4-(-1) )^{2} }[/tex]

LM = [tex]\sqrt{(-9)^{2} +(5)^{2} }[/tex]

LM = √106

LM = 10.29

The distance between the points

d = LM = 10.24

Answer:

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.

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.

Answer:

x = 65

Step-by-step explanation:

To solve the equation, we write it in radical form:

[tex]5\, \sqrt[3]{x-1} = 20[/tex]

Then, we divide both sides by 5 to isolate the root:

[tex]\sqrt[3]{x-1} = \frac{20}{5} \\\sqrt[3]{x-1} =4[/tex]

and next, we raise both sides of the equation to the power 3 so as to free the expression in x from the root:

[tex]x-1=4^3\\x-1=64[/tex]

now we add 1 to both sides to isolate x:

x = 65

Step-by-step explanation:

a). Since, 20% of the total diagram is represented by one fifth part of the total length.

Therefore, by adding all parts we will get 100% weight of the adult puppy.

20% of the part = 9 pounds

So the total weight of the adult puppy = 9 + 9 + 9 + 9 + 9

                                                         = 45 pounds

b). Weight of the puppy =  9 pounds

    Weight of a adult = 45 pounds

    Therefore, fraction that represents the weight of the puppy as compared to the weight of an adult = [tex]\frac{9}{45}[/tex]

                                         = [tex]\frac{1}{5}[/tex]

Answer:

Question 1 Answer: The adult weight will be 45 pounds.

Question 2 Answer: The puppy is ⅕ of its adult weight.
