Answer:
The answer is at the bottom!!
Step-by-step explanation:
Another word for finding the opposite of an integer is negative number of an integer.
Decrease, spend, and decline are examples of words that mean negative. An integer is any positive whole number or its opposite. Here, opposite means sign. So a positive integer has a negative opposite and vice versa.
Hope this helps!!
What is the base 5 representation of the number 219?
The easiest way to do this is to start with the power of 5 that is just under 219.
125 would be the closest power of 5
Now subtract 125 from 219 = 94
=====================
The highest power of 5 closest to 94 is 25. You have to multiply 25 * 3 to get a number close enough to 94 that leaves a remainder under 25
94 - 75 = 19
=======================
19 - 3 * 5 = 4 Same argument as above.
219_10 = 1334_5

28% of US adults say they are more likely to make purchases during a sales tax holiday. You randomly select 10 adults. Find the probability that the number of adults who say they are more likely to make purchases during a sales tax holiday is (a) exactly two, (b) more than two, and (c) between two and five, inclusive.
Answer:
a
[tex]P(X = 2) = 0.2547[/tex]
b
[tex]P(X > 2) = 0.5623 [/tex]
c
[tex]P(2 \le X \le 5 ) = 0.7817 [/tex]
Step-by-step explanation:
From the question we are told that
The proportion of US adults who say that they are likely to make purchase during a sale tax holiday is
[tex]p = 0.28[/tex]
The sample size is n = 10
Generally the distribution of US adults who say that they are likely to make purchase during a sale tax holiday, follows a binomial distribution
i.e
[tex]X \~ \ \ \ B(n , p)[/tex]
and the probability distribution function for binomial distribution is
[tex]P(X = x) = ^{n}C_x * p^x * (1- p)^{n-x}[/tex]
Here C stands for combination hence we are going to be making use of the combination function in our calculators
Generally the probability number of adult is exactly 2 is mathematically represented as
[tex]P(X = 2) = ^{10}C_2 * (0.28)^2 * (1- 0.28)^{10-2}[/tex]
=> [tex]P(X = 2) = 45 * 0.0784 * 0.0722[/tex]
=> [tex]P(X = 2) = 0.2547[/tex]
Generally the probability number of adult is more than 2 is mathematically represented as
[tex]P(X > 2) = 1- [P(X \le 2) ][/tex]
[tex]P(X > 2) = 1- [[P(X = 0)] +[P(X = 1) ] + [P(X = 2)] ][/tex]
=> [tex]P(X > 2) = 1- [^{10}C_0 * (0.28)^0 * (1- 0.28)^{10-0}] +[^{10}C_1 * (0.28)^1 * (1- 0.28)^{10-1}] + [^{10}C_2 * 0.28^2 * (1- 0.28)^{10-2}] ][/tex]
=> [tex]P(X > 2) = 1- [0.0374 + 0.1456 + 0.2547 [/tex]
=> [tex]P(X > 2) = 0.5623 [/tex]
Generally the probability number of adult is between two and five, inclusive is mathematically represented as
[tex]P(2 \le X \le 5 ) = [P(X = 2 ) + P(X = 3 ) +P(X = 4) + P(X= 5 )] [/tex]
=> [tex]P(2 \le X \le 5 ) = [[^{10}C_32 * 0.28^2 * (1- 0.28)^{10-2}] + [^{10}C_3* 0.28^3 * (1- 0.28)^{10-3}] +[^{10}C_4 * 0.28^4 * (1- 0.82)^{10-4}] + [^{10}C_5 * 0.28^5 * (1- 0.28)^{10-5}]] [/tex]
=> [tex]P(2 \le X \le 5 ) = [[0.2547] + [120* 0.02195 * 0.1003] +[210 * 0.00615 * 0.1393] + [252 * 0.0017 * 0.1935]] [/tex]
=> [tex]P(2 \le X \le 5 ) = [[0.2547] + [0.2642] +[0.1799] + [0.0829] [/tex]
=> [tex]P(2 \le X \le 5 ) = 0.7817 [/tex]
Consider the following sequence of numbers.
3,-9,27,-81,...
I need common ratio & sum of 1st five terms
Answer:
Please check the explanation
Step-by-step explanation:
Given the sequence
[tex]3,-9,27,-81,...[/tex]
A geometric sequence has a constant ratio and is defined by
[tex]a_n=a_0\cdot r^{n-1}[/tex]
Computing the ratios of all the adjacent terms
[tex]r=\frac{a_n+1}{a_n}[/tex]
[tex]\frac{-9}{3}=-3,\:\quad \frac{27}{-9}=-3,\:\quad \frac{-81}{27}=-3[/tex]
The ratio of all the adjacent terms is the same and equal to
[tex]r=-3[/tex]
Therefore, the common ratio is:
r = -3Determining the sum of 1st five terms
As the first element is
[tex]a_1=3[/tex]
[tex]r=-3[/tex]
Geometric sequence sum formula is given by
[tex]a_1\frac{1-r^n}{1-r}[/tex]
Plugin the values
[tex]n=5,\:\spacea_1=3,\:\spacer=-3[/tex]
[tex]a_1\frac{1-r^n}{1-r}=3\cdot \:\frac{1-\left(-3\right)^5}{1-\left(-3\right)}[/tex]
[tex]=3\cdot \frac{1-\left(-3\right)^5}{1+3}[/tex]
[tex]=\frac{\left(1-\left(-3\right)^5\right)\cdot \:3}{1+3}[/tex]
[tex]=\frac{732}{1+3}[/tex] ∵
[tex]=\frac{732}{4}[/tex]
[tex]=183[/tex]
Therefore, the sum of the first five terms of the sequence is: 183

two supplementary angles differ by 34. find the angles..
Answer:
107°
73°
Step-by-step explanation:
Let the two supplementary angles be x° and y°.
x + y = 180....(1)
Since, supplementary angles differ by 34.
Therefore,
x - y = 34....(2)
Adding equations (1) & (2)
x + y = 180
x - y = 34
_________
2x = 214
x = 214/2
x = 107°
Plug x = 107 in equation (1)
107 + y = 180
y = 180- 107
y = 73°

The slope intercept form of a linear equation is y=mx+b,where x and y are coordianates of an ordered pair, m is the slope of the line, and b is where the Crosse...
Answer:
The equivalent equation solved for x is x = (y-b)/m
Step-by-step explanation:
Here is the complete question:
The slope-intercept form of a linear equation is y = mx + b, where x and y are coordinates of an ordered pair, m is the slope of the line, and b is where the line crosses the y-axis.
Which is an equivalent equation solved for x?
x = y-bmx = y-b over m
x= my + b
m=y−bxm is equal to the fraction with numerator y minus b and denominator x
x=y−bm
Step-by-step explanation:
To determine the equivalent equation solved for x, we will make x the subject of the formula.
From the given equation,
y = mx + b
To make x the subject of the equation,
First, add -b to both sides of the equation, so that we get
y +(-b) = mx +b +(-b)
Then, we will get
y-b = mx +b -b
y-b = mx
Finally, to make x the subject of the equation, we will divide both sides by the coefficient of x ( that is, m)
(y-b) / m = mx / m
Then,
(y-b)/m = x
∴ x = (y-b)/m
Hence, the equivalent equation solved for x is x = (y-b)/m.
The first option is correct
x = (y-b)/m = y-b over m

can someone help me with this please and explain what a term is
Answer:
3y
Step-by-step explanation:
A term is a mathematical expression, in this case a number multiplied by a variable.
Like terms would mean anything that is equal to 3x.
Because 3 is a constant number, any like terms have to have the number 3 in it, so we can eliminate 5x, -2x, 7y, and x because they don't have a 3.
y is a variable which is a stand-in for an unknown number, and it can be switched out with any one variable. That means the only possible answer is 3y
As a plane takes off it ascends at a 20 degree angle of elevation. If the plane has been traveling at an average rate of 290 ft/s and continues to ascend at the same angle, then how high is the plane after 10 seconds (the plane has traveled 2900ft).
Given :
As a plane takes off it ascends at a 20 degree angle of elevation.
If the plane has been travelling at an average rate of 290 ft/s and continues to ascend at the same angle.
To Find :
How high is the plane after 10 seconds.
Solution :
Distance travelled by plane, D = 2900 ft.
Angle of elevation, Ф = 20°.
Height gained is given by :
[tex]H = Dsin\ \phi[/tex]
H = 2900 × sin 20°
H = 991.86 ft.
Therefore, height of plane after 10 seconds is 991.86 ft.
Hence, this is the required solution.
What is the answer to x?
Answer:
x=24ft.............
Answer:
x = 24 ft.
Step-by-step explanation:
The 13 and the 5 and both multiplied by 2 to find the lengths of the second triangle. So, the 12 should also be multiplied by 2 to find the value of x:
12 * 2 = 24
x is 24 ft.

Mrs. Brown gave her daughter, Shane, $250 to open a savings account. Each month, Mrs. Brown gives Shane $50 to deposit into her savings account. Which equation can be used to find m, the number of months after opening her account when Shane will have $800 in her savings account?
Answer:
Equation ; 800 = 50m + 250Number of months = 11 monthsStep-by-step explanation:
This is a linear relationship which means that it follows the equation;
y = mx + c
y will be the total after some months so will be $800
m will be the number of months
x is the amount the account increases by every month which is $50 here
c is the amount in the account before the $50 started being added which is $250.
800 = 50m + 250
50m = 800 - 250
m = (800 - 250) / 50
m = 11 months
There were 306 students in the cafeteria. After some went outside, there were 249 students left in the cafeteria. How many students went outside? Write an equation and solve the problem?
Answer:
The equation to solve the problem is
306 = 249 + x
x = 306 - 249
Hence:
57 students went outside
Step-by-step explanation:
Let the number of students outside be represented by x
Hence:
Number of students in the cafeteria = Number of students inside - Number of students who went outside
We are told:
There were 306 students in the cafeteria. After some went outside, there were 249 students left in the cafeteria.
The equation to solve the problem is given as:
306 = 249 + x
x = 306 - 249
Hence:
x = 57
57 students went outside

a) La aceleración:
b) El tiempo que tarda en detenerse:
Responder:
1.439 s
-9,645 m / s²
Explicación paso a paso:
Dado que:
Velocidad en m / s = (50 * 1000) / 3600 = 13.899 m / s
Distancia (d) = 20
Tiempo = distancia / velocidad
Tiempo = 20 / 13.889
Tiempo = 1.439 s
Aceleración (a):
Cambio de velocidad / tiempo empleado
= (0 - 13,889) / 1,439
- 13.889 / 1.439
= -9,645 m / s²
