Which accurately shows how to use inverse operations to find the value of a in a + 5 = 14?

Answers

Answer 1

To use inverse to solve the operation we shall proceed as follows:
a+5=14
using the additive inverse property we shall have:
a+5+(-5)=14+(-5)
simplifying the above we get:
a+5-5=14-5
a+0=9
thus
a=9

2. Then, you have:

√(x0-a)^2+(y0-b)^[2=|y0-10|

3. When you susbtitute values and simplify it, you obtain:

(√(x0-4)^2+(y0-0)^2)^2=(y0-10)^2
(x0-4)^2+y0^2=(y0-10)^2

4. Now, you must clear y, and you will have:

A standard number cube is tossed. Find P (3 or odd)

A. 1/2
B. 2/3
C. 1/3
D. 1/6

Answers

Total number of possible outcomes = 6

Total number of outcomes with 3 or odd = 3
They are : 1, 3, 5

P(3 or odd) = 3/6 = 1/2

Answer: 1/2

E = event space = set of outcomes we want to happen
E = set of numbers that are either 3 or odd
E = {1, 3, 5}

S = sample space = set of all possible outcomes
S = set of all the values on the standard number cube (aka dice)
S = {1, 2, 3, 4, 5, 6}

There are 3 items in the event space out of 6 total in the sample space
Using math notation, we can say n(E) = 3 and n(S) = 6. The small n means "number". So writing "n(E)" means "number of items in the event space".

So,
P(3 or odd) = n(E)/n(S)
P(3 or odd) = 3/6
P(3 or odd) = 1/2

The probability as a fraction is 1/2, which is 0.5 in decimal form. This represents a chance of 50%. Note: since 3 is an odd number, saying "P(3 or odd)" is the same as just saying "P(odd)"

c.r = .75
d.r = .90

Answers

Just had this problem the answer is D.

Answer:

d) r=0.90

Step-by-step explanation:

When the r value is closer to +1 or -1, it indicates that there is a stronger linear relationship between the two variables. A correlation nearerto -1 is a strong negative correlation while a correlation of 0.10 would be a weak positive correlation.

Correlation coefficient measures the strength of association between two variables.

It may be positive or negative.

If nearer to 1 or - there is strong correlation

Write an equation of the direct variation that includes the point (6, –2). y = –3x

Answers

Answer:

-1/3x is the answer

Step-by-step explanation:

Do the problem.

An equation of the direct variation that includes the point (6, –2) is y = -1/3(x).

What is a direct variation?

In Mathematics, a direct variation is also referred to as direct proportion and it can be modeled by using the following mathematical expression or function:

y = kx

Where:

y represents the y-variable or dependent variable.x represents the x-variable or independent variable.k represents the constant of proportionality.

Under direct variation, the value of x represent an independent variable while the value of y represents the dependent variable. Therefore, the constant of proportionality (variation) can be calculated as follows:

Constant of proportionality (k) = y/x

Constant of proportionality (k) = -2/6

Constant of proportionality (k) = -1/3

Therefore, the required equation is given by;

y = kx

y = -1/3(x)

The equation for a projectile's height versus time is h(t)=-16t^2+Vt+h. A tennis ball machine serves a ball vertically into the air from a height of 2 feet, with an initial speed of 130 feet per second. Which equation correctly models the ball's height as a function of time?

Answers

For this case we must use the projectile equation for this problem.
We have then:
h (t) = - 16t ^ 2 + Vt + h
Where,
V: initial speed
h: height
For the tennis ball we have:
h (t) = - 16t ^ 2 + 130t + 2
Answer:
An equation that correctly models the ball's height as a function of time is:
h (t) = - 16t ^ 2 + 130t + 2

The maximum height at the moment is 266.0625 ft.

Projectile's height

The equation for a projectile's height versus time is

[tex]&h(t)=-16 t^{2}+V t+h \\[/tex]

h = 2

V = 130

Substitute these values into the function

[tex]$h(t)=-16 t^{2}+130 t+2$[/tex]

Take the first derivative

[tex]$h^{\prime}(t)=-16* 2 t+130[/tex]

[tex]=-32 t+130$[/tex]

Equate the derivative with zero [tex]$h^{\prime}(t)=0$[/tex].

Solve the equation -32 t + 130=0

32 t = -130

t = -130 /(-32)

= 4.0625(s) .

Find the maximum height at the moment

t = 4.0625 (s)

h(4.0625) [tex]= -16(4.0625)^{2}+130 * 4.0625+2[/tex]

= - 264.0625+528.125+2

= 266.0625 ft.

Therefore, the maximum height at the moment is 266.0625 ft.

A and b are independent events. the probability that a will happen is 1/4 and the probability that b will happen is also 1/4. what is the probability they will both happen?

Answers

To find the probability of both things happening you just have to multiply them by each other.

1/4*1/4=1/16

Final answer:

For independent events A and B, the probability of both happening is the product of their individual probabilities. In this case, the probability of both A and B happening is 1/16.

Explanation:

In the field of probability in mathematics, when dealing with independent events like A and B in your question, the probability of both A and B happening (denoted as P(A AND B)) is calculated by multiplying the probability of A happening (P(A)) by the probability of B happening (P(B)) This is known as the multiplication rule for independent events.

So, if the probability that A will happen (P(A)) is 1/4, and the probability that B will happen (P(B)) is also 1/4, then the probability that both A and B will happen (P(A AND B)) is (1/4) * (1/4) = 1/16.

Answers

Increment = 6% = 0.06
The explicit formula for the series is;
C(n) = C(n-1)(1.06), where n = nth month, C(n-1) = cost during previous month, C(n) = cost in month n

Applying the explicit formula;
Current cost = $150
2nd month cost = 150*1.06 = $159
3rd month cost = 159*1.06 = $168.54

The second option is correct.

A sporting goods store sells 2 fishing reels and 5 fishing rods for $195. Later, they sell 4 fishing reels and 3 fishing rods for $131. Find the price of each item.

Answers

Let
Fishing reel = x
Fishing rods = y

Therefore,
2x + 5y = 195 ---- 1
4x + 3y = 131 ---- 2

Solving 1 and 2 above;
Multiply expression 1 by 2 and subtract 2 from the results;
4x + 10y = 390
4x + 3y = 131
-------------------
0x + 7y = 259 => y = 259/7 = 37

Using the value of y in expression 1;
2x + 5(37) = 195
2x + 185 = 195
2x = 10
x = 10/2 = 5

Therefore, the price of fishing reels is $5 and fishing rods is $37.

Rent-a-car rents compact cars for a fixed amount per day plus a fixed amount for each mile driven Benito rented a car for 6 days drove it 550 miles and spent $337. Lisa rented the same car for 3 days drove it 350 miles and spent $185. What is the charge per day and charge per mile for the compact car?

Please show all work! TYSM! ☺♥♫

Answers

If charge per day =x
and charge per mile =y

6x + 550y = 337
3x + 350y = 185

multiple the second equation by 2
6x+700y=370
subtract the first equation from this equation
150y=33
y=0.22

Now we plug the y back in to one of the initial equations to get the value of x

3x+350(0.22)=185
x=36

Charge per day is $36 and charge per mile is $0.22

The charge per day and charge per mile for the compact car is $36 and $0.22 respectively

let

x = charge per day

y = charge per mile

6x + 550y = 337 (1)

3x + 350y = 185 (2)

multiply (2) by 2

6x + 700y = 370 (3)

6x + 550y = 337 (1)

subtract (1) from (3)

700y - 550y = 370 - 337

150y = 33

y = 33/150

y = 0.22

substitute y = 0.22 into (2)

3x + 350y = 185

3x + 350(0.22) = 185

3x + 77 = 185

3x = 185 - 77

3x = 108

x = 108/3

x = 36

Therefore, charge per day and charge per mile for the compact car is $36 and $0.22 respectively

Answer: B. [tex]\frac{16}{25}[/tex]

Step-by-step explanation:

Also, the scale factor of dilation is the ratio of the sides of new shape to the corresponding sides of the original shape .

Let k be the scale factor of dilation, then

Given : Original shape - larger prism

New shape - smaller prism

Surface area of prism with all sides equal (a)=[tex]4a^2[/tex]

Surface area of original prism =[tex]4(10)^2=400[/tex]

Answers

the picture in the attached figure

we know that
In a square pyramid we have five faces, 4 triangles and 1 square. So to determine surface area we need to take the areas of the triangles and square and add them all up

The square's area is relatively simple:

A=b²
A=6²=36 ft²

But now let's observe the triangles, a triangle's area is:

A=(1/2)*b*h

the base is equal to 6 ft

b=6 ft

AC=BC----------> because the angle is 45°

AC=6 ft/2----> 3 ft

BC=3 ft

A=(1/2)*6*3----> 9 ft²

Multiply the triangle's area by four to account for all four triangular faces and add the squares area for your answer

Surface area=36 +4*9-----> 72 ft²
