Answer:

The answer 28.27 *2 = 56.54

Step-by-step explanation:

A= πr^2

The area of Maria's circle, which is double the area of circle G is: 56.52 sq. cm.

Given:

Radius (r) of circle G = 3 units

Area of circle G = π(3²) = 28.26 sq. units.

Area of Maria's circle = 2(area of circle G)

Therefore:

Area of Maria's circle = 2(28.26)

Area of Maria's circle = 56.52 sq. cm.

Answer:

x = 30°

y = 60°

z = 96°

Step-by-step explanation:

Well the angle from the center that intercepts 120° is equal to 120° since it is a central angle.

y = 60° because oof supplementary angles.

The measure of z is 48 * 2 because the 48° is an inscribed angle.

z = 96°

And, the arc that angle y intercepts is also the arc the x intercepts.

That arc is 60° because 180° - 120° = 60°

x is an inscribed angle, so x = 1/2 * 60°

x = 30°

Answer:

The amount of loan ($20000) after 48 months with 1.5% (0.015) interest rate  is calculated by:

A = 20000 x (1 + 0.015/12)^48

   = 21235.94$

Monthly payment of Grace is calculated by:

M = A/number of month

   = 21235.94/48 = 442.4 = ~444$

Answer:

35 years old.

Step-by-step explanation:

To find the age of Gwen, multiply Robin's age, which is 11, by 3, which gives you 33. Then add two to 33 to get Gwen's age, which is 35 years.

Answer:

Gwen is 35 years old

Step-by-step explanation:

In order to understand the word problem better, I turned it into and equation.

Since Gwen is 2 years older than 3 times Robins age, the equation would be:

Gwens age = (3 • Robins age) + 2

G = (3 • 11) + 2

G = (33) + 2

G = 35

So Gwen is 35 years old.

Answer:

24618 mm^3

Step-by-step explanation:

V = pi r^2 h

We know the diameter

r = d2/ = 28/2 = 14

V = pi (14)^2 (40)

Approximating pi to 3.14

V = (3.14 ) 14^2 *40

V =24617.6

Answer:

The value of z test statistic is 2.871.

Step-by-step explanation:

We are given that a software firm survey of 564 randomly selected adults showed that 56​% of them would erase all of their personal information online if they could. Find the value of the test statistic.

Let p = population proportion of adults who would erase all of their personal information online if they could.

So, Null Hypothesis, [tex]H_0[/tex] : p [tex]\leq[/tex] 50%      {means that adults who would erase all of their personal information online if they could is less than or equal to 50%}

Alternate Hypothesis, [tex]H_A[/tex] : p > 50%     {means that majority of adults would erase all of their personal information online if they could}

The test statistics that would be used here One-sample z test for proportions;

                            T.S. =  [tex]\frac{\hat p-p}{\sqrt\frac{\hat p(1-\hat p)}{n} {} }[/tex]  ~ N(0,1)

where, [tex]\hat p[/tex] = sample proportion of adults who would erase all of their personal information online if they could = 56%

           n = sample of adults taken = 564

So, the test statistics  =  [tex]\frac{0.56-0.50}{\sqrt\frac{0.56(1-0.56)}{564} {} }[/tex]

                                       =  2.871

The value of z test statistic is 2.871.

Answer:

A

Step-by-step explanation:

Here you can check by trying points along the number line that are not included in the other number line. For example, x = -3 is included in A but not in B and x = -5 is included in B but not in A.

If x = -3, the inequality 5x > -20 is true because -15 > -20.

If x = -5, the inequality 5x > -20 is false because -25 is not > -20.

There for the answer should include x = -3 and not include x = -5, so A.

Answer:

2-1=1 so A. is 100% more than B because A is 2 times bigger than B.

A. is the answer 2:1

Hope this helps

Step-by-step explanation:

The option that shows the ration A: B is Option C - 1:2. See the rationale below.

If A is 100% more than B, it means that A is equal to B plus 100% of B. In other words, A is twice the value of B.

Therefore, the ratio of A to B is 1:2, indicating that A is twice as much as B.

Recall that a ratio is a quantitative relationship between two or more quantities, indicating how many times one quantity is contained or repeated in relation to another quantity.

It is expressed as a fraction or with a colon (:), representing the relative comparison of the quantities.

Answer:

a) [tex] t_{\alpha}= 1.753[/tex]

b) [tex] t_{\alpha}= -1.383[/tex]

c) [tex] t_{\alpha/2}= \pm 2.179[/tex]

Step-by-step explanation:

Part a

For this case we know that the degrees of freedom are:

[tex] df = 15[/tex]

And we want a right tailed test so then we need to find in the t distribution with degrees of freedom =15 a critical value who accumulate 0.05 of the area in the right and we got:

[tex] t_{\alpha}= 1.753[/tex]

Part b

For this case the significance is [tex]\alpha=0.1[/tex] the degrees of freedom are:

[tex] df = n-1= 10-1=9[/tex]

And since is a left tailed test the critical value for this case would be:

[tex] t_{\alpha}= -1.383[/tex]

Part c

For this case the significance is [tex]\alpha=0.05[/tex] and [tex]\alpha/2=0.025[/tex] the degrees of freedom are:

[tex] df = n-1= 13-1=12[/tex]

And since is a two tailed test the critical values for this case would be:

All angles are of triangle and thus give sum of 180⁰

x + 5 + 7x - 5 + x = 180⁰

9x = 180⁰

x = 20⁰

Answer:

it's 20

Step-by-step explanation:

(X+5)° + (7x-5)° + x°= 180° { sum of the three angles of the triangle is 180°}

X+5+7x-5+X = 180

X+7x+X+5-5= 180

9x+0 = 180

9x = 180

therefore X= 180/9

The answer to this problem is 1/6.

The share of the pizza each friend will have is 1 / 6.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that three friends equally share 1/2 of a pizza. The fraction of the pizza shared by each friend will be:-

Fraction of pizza = ( 1 / 2 ) x ( 1 / 3 )

Fraction of pizza = ( 1 / 6 )

Therefore, the share of the pizza each friend will have is 1 / 6.

Answer:

The dimensions of the vegetable patch is 8 m by 7 m.

Step-by-step explanation:

Area of a vegetable patch is 56 square meters and the perimeter is 30 m.

If l is length and b is breadth, then area and perimeter of a rectangle is given by :

[tex]A=l\times b[/tex]

[tex]P=2(l+b)[/tex]

Substituting the values in the above formulas as :

[tex]l\times b=56\ ....(1)[/tex]

and

[tex]2(l+b)=30\\\\l+b=15\ .....(2)[/tex]

We need to solve equation (1) and (2) to find the values of l and b such that :

Equation (2), l = 15 - b

Equation (1) becomes,

[tex](15-b)b=56\\\\b=7\ m, 8\ m[/tex]

If b = 7 m, so, l = 8 m

If b = 8 m, l = 7 m

So, the dimensions of the vegetable patch is 8 m by 7 m.

The multiplier for a base-10 (decimal) number system is 10 as you move one place to the left. In some other base, the multiplier is that base. In a binary (base-2) number system, each "bit" increases in value by a factor of 2 as you move to the left.
