Answer:

705/100 grams cann be covered by the basic postage

Step-by-step explanation:

Given

Basic Postage

[tex]Weight < 7.5g[/tex]

Heavy letters

[tex]Weight \ge 7.5g[/tex]

Required

Can [tex]705/100[/tex] be covered in basic postage?

We have:

[tex]Weight = 705/100\ g[/tex]

[tex]Weight = 7.05\ g[/tex]

By comparing the above with the range of basic postage ---- [tex]Weight < 7.5g[/tex]

We have:

[tex]7.05g < 7.5g[/tex]

Since the above inequality is true, then the letter can be covered

Answer:

You would have $1552.9 after 10 years.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

You currently have $500 saved up.

This means that [tex]P = 500[/tex]

12% interest, compounded annually.

This means that [tex]r = 0.12, n = 1[/tex].

How much money would you have after 10 years?

This is A(10). So

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]A(10) = 500(1 + \frac{0.12}{1})^{10}[/tex]

[tex]A(10) = 1552.9[/tex]

You would have $1552.9 after 10 years.

The relation represented by graph A can be stated as function.

Thus, option (A) is correct.

A) The graph have input values {-5, -4, 0, 3, 4, 7}

and, all input have distinct output values {7, 5, 0, -1, -5}.

So, the graph is function.

B) The set {(-8, 8), (-6, 5), (-6, 4), (-3, 1), (-1, 0)} is not function.

Here, the input value -6 have two distinct output 5 and 4.

C) The table is not function.

Here, the input value 15 have outputs 2 and 3.

and 20 have two distinct output as 4 and 5.

D) The graph is not function as using verticals line test the curve have two same input value with different output value.

Thus, option (A) is correct.

Answer:

The mean number of tiebreakers is of 35.2 and the standard deviation is of 5.44.

Step-by-step explanation:

For each set, there are only two possible outcomes. Either it goes to a tiebreak, or it does not. The probability of a set going to a tiebreak is independent of any other set, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

The probability that a tennis set will go to a tiebreaker is 16%.

This means that [tex]p = 0.16[/tex]

220 randomly selected tennis sets

This means that [tex]n = 220[/tex]

What is the mean and the standard deviation of the number of tiebreakers?

[tex]E(X) = np = 220*0.16 = 35.2[/tex]

[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{220*0.16*0.84} = 5.44[/tex]

The mean number of tiebreakers is of 35.2 and the standard deviation is of 5.44.

Answer:

f(5) = 100

Step-by-step explanation:

for n = 5 means we will plug in 5 for every instance of n.

f(5) = 10•2(5)

Multiply.

f(5) = 10•10

Answer:

x = 17.5 degrees

Step-by-step explanation:

So with this, it gives you the angle measure and the terms for that angle measure for Angle EDC. Since these are equal, set them equal to each other.

2x+10 = 45

Move over the 10

2x = 35

Divide by 2

x = 17.5 degrees

That's all.

Answer: Choice B)  -1, -2, -3, -4, -5

All of the x coordinates change from positive to negative. Meaning that something like x = 2 becomes x = -2.

More specifically, the point (2,4) moves to (-2,4).

The y coordinate of each point stays the same.

Answer:

[tex]c=\frac{ab}{a+b}[/tex]

Step-by-step explanation:

To solve for [tex]c[/tex], our goal is to isolate it.

Start by multiply both sides by [tex]ab[/tex]. That way, we'll still have only one term with [tex]c[/tex], but we'll be able to get rid of two messy fractions.

[tex]b+a=\frac{ab}{c}[/tex]

Taking the reciprocal of both sides:

[tex]\frac{1}{a+b}=\frac{c}{ab},\\c=\boxed{\frac{ab}{a+b}}[/tex]

*Note: You cannot take the reciprocal of both sides if you're adding fractions. This is why we can't just take the reciprocal of both sides in the initial equation.

Alternate solution:

[tex]\frac{1}{a}+\frac{1}{b}=\frac{b}{ab}+\frac{a}{ab}=\frac{1}{c},\\\\\frac{b+a}{ab}=\frac{1}{c},\\\\c=\frac{ab}{b+a}=\boxed{\frac{ab}{a+b}}[/tex]

Answer:

c=ab

a+b

Step-by-step explanation:

1 + 1= 1

a. b. c

a+b = c

ab

a+b= ab

ac+bc=ab

c(a+b)=ab

c(a+b)=ab

The measure of m∠z is 135°.

A closed two-dimensional figure having eight sides, eight vertices, and eight interior angles is known as an octagon. An octagon is referred to as a regular octagon if all of its sides and internal angles are of equal length; otherwise, it is referred to as an irregular octagon.

As, Each inner angle is the same measure because it is a regular octagon.

To calculate the interior angle sum of a polygon, we have a formula.

The total internal angle of a polygon

= (n -2)180°, where "n" is the number of sides.

Here, n = 8

Then, sum of the interior angles.

= (8 -2)180

= 6 x 180

= 1080°

Thus, the measure of m∠z = 1080/ 8  = 135°

Answer:

Step-by-step explanation:

I'm going to go out on a limb here and guess that you are looking for the answer to the measure of arc DAB, since we already know that angle DAB is 78. Angle DAB is an inscribed angle. That inscribed angle intercepts arc DCB, and the theorem for that is that an inscribed angle is half the measure of the arc it intercepts. That means that arc DCB measures twice 78, so arc DCB measures 156 degrees. Since the measure around the outside of any circle is 360 degrees, arc DAB is 360 - 156 which is 204 degrees. If this is not what you are looking for, sorry and be more specific next time.

• Length of the metal sheet = 9.96 m

• Breadth of the metal sheet = 5.08 m

As we know that,

★ Perimeter of rectangle = 2(length + breadth)

→ Perimeter of sheet = 2(9.96 + 5.08) m

→ Perimeter of sheet = 2(15.04) m

→ Perimeter of sheet = 30.08 m

Therefore, perimeter of the rectangular sheet is 30.08 m.

Answer:

7.14%

Step-by-step explanation:

A fair number cube has 6 sides while a normal spinner has 7 different colors. In order to find the probability of Jack getting a number less than 4 and lands on blue, we need to find the probability of each individual event and multiply them together. Since the cube has six sides and 3 options that are less than 4 then the probability of getting less than 4 is 3/6. On the wheel there are 7 colors and only one is blue, therefore, the probability is 1/7. Now we multiply these fractions together.

[tex]\frac{3 * 1}{6 * 7} = \frac{3}{42}[/tex] or 0.0714 or 7.14%

Therefore, the probability of this event happening is 7.14%

The probability of this event is 7.14%.

A fair number cube has 6 sides.

While a normal spinner has 7 different colors.
