Answer:

A'(-4,-3)

Step-by-step explanation:

use formula of reflection over y axis

(x,y)=(-x,y)

A(4,-3)=A'(-4,-3)

the answer is (-4,-3).

Answer:

-2

Step-by-step explanation:

If you draw a line from a to a^1 and cut that line in half, that’s the line of reflection (or think of it as a line of symmetry if that helps). You use a and a^1 because a^1 is the reflection of point a

Answer:

[tex]V_c=452.16\ mm^3[/tex]

Step-by-step explanation:

Given that,

The volume of a sphere is 904.32 mm³.

The volume of a cone that has the same height and circular base with the same diameter is:

[tex]V_c=\dfrac{1}{3}\pi r^2 \times 2r=\dfrac{2}{3}\pi r^3[/tex]

The volume of a sphere with the same radius is:

[tex]V_s=\dfrac{4}{3}\pi r^3=2\times \dfrac{2}{3}\pi r^3[/tex]

So, the volume of sphere is :

[tex]V_c=\dfrac{V_s}{2}\\\\V_c=\dfrac{904.32 }{2}\\\\V_c=452.16\ mm^3[/tex]

So, the volume of the cone is [tex]452.16\ mm^3[/tex].

Answer:

C) 5.66

Step-by-step explanation:

For a 45-45-90 triangle, the length of each leg length (not including the hypotenuse) is congruent to each other. If 8=y√2, then y=8/√2=4√2=5.66

Answer:

5.66

Step-by-step explanation:

take 45 degree as reference angle

using cos rule

cos 45 =adjacent /hypotenuse

Answer:

Third table

Step-by-step explanation:

For the relationship to be proportional

y/x = constant

First table y/x = 8/4 = 2    then 7/11 doesn't =2  so it is not

Second table y/x =52/5 = 5    then 49/7 doesn't =5  so it is not

Third table y/x = 3/6=1/2    then 5/10 = 1/2   then 7/14 = 1/2  it is proportional

Last table y/x = 6/3 = 2    then 11/8 doesn't =2  so it is not

Answer:

[tex]\frac{2}{8} +\frac{2}{3} =\frac{12}{48} +\frac{32}{48} =\frac{44}{48} =\frac{11}{12}[/tex]

Step-by-step explanation:

To have a common denominator of 48, we need to solve for numerator and denominator!

[tex]\frac{2}{8} =\frac{12}{48}[/tex]        If you multiply the denominator by 6 just to get to 48, you must multiply it to the numerator as well.

[tex]\frac{2}{3} =\frac{32}{48}[/tex]        If you multiply the denominator by 16 just to get to 48, you must multiply it to the numerator as well.

Then we have those results in the line: [tex]\frac{12}{48} +\frac{32}{48}[/tex]

Then we added those fractions to get to 44/48 and simplify it by 4

Answer:

<J = 60.26

<L = 28.84

JL = [tex]2\sqrt{65}[/tex]

Step-by-step explanation:

One is given that triangle (JKL) is a right triangle. The measurements for the legs (JK) and (KL) are given; (8) and (14) respectively. One can use the Pythagorean theorem to solve for the unknown side, the hypotenuse. The Pythagorean theorem states the following,

[tex]a^2+b^2=c^2[/tex]

Where (a) and (b) are the legs or sides adjacent to the right angle of the right triangle. (c) is the hypotenuse or the side opposite the right angle of the right triangle. Substitute in the given values and solve for the unknown,

[tex]a^2+b^2=c^2\\\\8^2+14^2=c^2\\\\64+196=c^2\\\\260=c^2\\\\2\sqrt{65}=c[/tex]

Now one has to find the unknown angles. This can be done using the right triangle trigonometric ratios. These ratios are used to describe the relationship between the sides and an angle of a triangle. These ratios are as follows,

[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adajcent}[/tex]

Bear in mind that the sides are named relative to the angle one is describing it from. Thus, the name of the (opposite) and (adjacent) sides change relative to the angle of description. However, the hypotenuse is the side opposite the right angle, this side never changes its name.

Solve for (<J)

Since one has the measures of all of the sides, one can use any ratio. In this case, let's use the ratio of tangent (tan).

[tex]tan(\theta)=\frac{opposite}{adjacent}\\\\\tan(\theta)=\frac{14}{8}\\\\\theta=tan^-1(\frac{14}{8})\\\\\theta=60.256[/tex]

Solve for (<L)

The sum of angles in any triangle is (180) degrees. One can use this property here. Form an equation by adding up all of the angle measures, and solve for (<L)

(<L) + (<J) + (<K) = 180

(<L) + 60.26 + 90 = 180

(<L) + 151.16 = 180

(<L) = 28.84

Answer: 0.973

Step-by-step explanation:

The probability mass function of geometric distribution is

[tex]f(x)=(1-p)^{x-1}p,\ \ \ x=1,2,3,...[/tex], p= probability of success on a trial.

As per given, we have

p=0.7

The probability that we'll have at most 3 orders [tex]P(X\leq3)=P(x=1)+P(x=2)+P(x=3)[/tex]

[tex]=(1-0.7)^{1-1}(0.7)+(1-0.7)^{2-1}(0.7)+(1-0.7)^{3-1}(0.7)\\\\=0.7+0.21+0.063\\\\=0.973[/tex]

hence, the required probability = 0.973

The probability that we'll have at most 3 orders will be "0.973".

According to the question,

→ [tex]x \sim Geometric (p)[/tex]

here,

p = 0.7

then,

→ [tex]P(X=x) = (1-p)^{x-1}\times p[/tex]

By putting the given values, we get

                   [tex]= (1-0.7)^{x-1}\times 0.7[/tex]

hence,

The probability that we'll have at most 3 orders will be:

→ [tex]P(X \leq 3)=P(X=1)+P(X=2)+P(X=3)[/tex]

                   [tex]=0.7+0.21+0.063[/tex]

                   [tex]=0.973[/tex]

Thus the above response is correct.

Answer:

Percentage of U.S resident who used the Internet for e-mail were Hispanic=9.19%

Step-by-step explanation:

We are given that

Population was Caucasian=64%

Population was African-American=11%

Population was Hispanic=10%

Let the population of U.S=10000

Now,

Population was Caucasian=[tex]\frac{64}{100}\times10000=6400[/tex]

Population was African-American=[tex]\frac{11}{100}\times 10000=1100[/tex]

Population was Hispanic=[tex]\frac{10}{100}\times 10000=1000[/tex]

Population of others=10000-(6400+1100+1000)=1500

Population of Caucasians used the Internet for e-mail=86% of 6400

Population of Caucasians used the Internet for e-mail=[tex]\frac{86}{100}\times 6400[/tex]

Population of Caucasians used the Internet for e-mail=5504

Population of African-American used the Internet for e-mail=77% of 1100

Population of African-American used the Internet for e-mail=[tex]\frac{77}{100}\times 1100=847[/tex]

Population of Hispanics used the Internet for e-mail=77% of 1000

Population of Hispanics used the Internet for e-mail=[tex]\frac{77}{100}\times 1000=770[/tex]

Population of others used the Internet for e-mail=84% of 1500

Population of others used the Internet for e-mail=[tex]\frac{84}{100}\times 1500=1260[/tex]

Step-by-step explanation:

The relative frequency for a 15% discount is 52.1%.

The relative frequency is the quotient of a particular frequency divided by the total number of frequencies.

Given:

A store is giving out cards labeled 1 through 10 when customers enter the store.

If the card is an even number, you get a 15% discount on your purchase that day.

The subgroup for even numbers = 2, 4, 6, 8, 10

The subgroup frequency = 56 + 50 + 54 + 49 + 54 = 263

The total frequency = 500

The relative frequency = 263/500 = 0.521 = 52.1%
