X + 15 > 20
Pls show steps
Answer:
X = 5
Step-by-step explanation:
You always do the inverse (opposite). 20 - 15 = 5, therefore the variable 'X' = 5. Also, if you add '6' to 'X', then it shall be ONE greater than 20.
Answer:
any real number greater than 5
Step-by-step explanation:
X+15> 20
X>20-15
X>5
(5,∞)
you can easily know by ;- 6+15>20
21>20 it's true

when does a linear equation have infinitely many solutions?
Answer:
An equation can have infinitely many solutions when it should satisfy some conditions. The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept. If the two lines have the same y-intercept and the slope, they are actually in the same exact line.
Step-by-step explanation:
Answer:
Step-by-step explanation:
A linear equation does not actually have solutions; rather, we find the locus of points ( x, y = f(x) ) and draw a straight line through them.
It is a SYSTEM of linear equations that may or may not have solution(s).
If one equation in this system is a multiple of the other, then the two equations represent the same line and the SYSTEM has infinitely many solutions. The graphs of the two equations coincide/overlap.

can't find probability
Answer: [tex]0.0756,\ 0.7599[/tex]
Step-by-step explanation:
Given
Probability that a coin will land head is [tex]0.3[/tex] i.e. probability of success is [tex]p=0.3[/tex] So, the probability of failure is [tex]q=1-0.3=0.7[/tex]
Using Binomial distribution for [tex]n=4[/tex]
(a) Probability that the coin will lead heads exactly 3 times
[tex]\Rightarrow P(3)=^4C_3(0.3)^3(0.7)^1\\\Rightarrow P(3)=4\times 0.7\times (0.3)^3\\\Rightarrow P(3)=0.0756[/tex]
(b)Probability that the coin lands head at least once
[tex]\Rightarrow 1-P(0)\\\Rightarrow 1-^4C_0(0.3)^0(0.7)^4\\\Rightarrow 1-1\cdot(0.7)^4\\\Rightarrow 0.7599[/tex]
Suppose that to make the golf team you need to score no more than 85 on average over 5 games. If you scored 82, 91, 79, and 85 in your first 4 games what is the highest score you can shoot in your 5th game and still make the team?
Answer:
88
Step-by-step explanation:
(82+91+79+85+s) ÷ 5 ≤ 85
(337 + s) ÷ 5 ≤ 85
cross-multiply to get:
337 + s ≤ 85(5)
337 + x ≤ 425
x ≤ 425 - 337
x ≤ 88

Match the hyperbolas to their vertices.
Answer:
see file below.
Step-by-step explanation:
The matching of hyperbolas to their vertices is shown below.
What is Equation of Hyperbola?The standard form of the equation of a hyperbola with center (h , k)
and transverse axis parallel to the x-axis is (x - h)²/a² - (y - k)²/b² = 1
1. (x + 2)²/3² - (y - 5)²/4² = 1
As, the standard form (x - h)²/a² - (y - k)²/b² = 1
Here a = 3 , b = 4 , h = -2 , k = 5
So, The coordinates of the vertices are (h ± a , k)
The coordinates of the vertices are (1 , 5) , (-5 , 5)
2. (x - 4)²/8² - (y + 2)²/9² = 1
As, the standard form (x - h)²/a² - (y - k)²/b² = 1
Here a = 8 , b = 9 , h = 4 , k = -2
So, The coordinates of the vertices are (h ± a , k)
The coordinates of the vertices are (12 , -2) , (-4 , -2)
3. (y + 5)²/15² - (x - 1)²/8² = 1
As, the standard form (x - h)²/a² - (y - k)²/b² = 1
Here a = 15 , b = 8 , h = -5 , k = 1
So, The coordinates of the vertices are (h ± a , k)
The coordinates of the vertices are (-20 , 1) , (10 , 1)
4. (x - 4)²/8² - (y + 2)²/6² = 1
As, the standard form (x - h)²/a² - (y - k)²/b² = 1
Here a = 8 , b = 6 , h = 4 , k = -2
So, The coordinates of the vertices are (h ± a , k)
The coordinates of the vertices are (12 , -2) , (-4 , -2)
5. (y - 3 )²/6² - (x + 7 )²/5² = 1
As, the standard form (x - h)²/a² - (y - k)²/b² = 1
Here a = 6 , b = 5 , h = 3 , k = -7
So, The coordinates of the vertices are (h ± a , k)
The coordinates of the vertices are (-3 , -7) , (9, -7)
6. (x - 3)²/5² - (y + 7)²/10² = 1
As, the standard form (x - h)²/a² - (y - k)²/b² = 1
Here a = 5 , b = 10 , h = 3 , k = -7
So, The coordinates of the vertices are (h ± a , k)
The coordinates of the vertices are (-2 , -7) , (8 , -7)
7. (y - 5 )²/7² - (x + 2 )²/8² = 1
As, the standard form (x - h)²/a² - (y - k)²/b² = 1
Here a = 7 , b = 8 , h = -2 , k = 5
So, The coordinates of the vertices are (h ± a , k)
The coordinates of the vertices are (5 , 5) , (-9, 5)

What is the amplitude of the graph of y = 2sin(4x - 1) + 3 ?
Answer: 2
Step-by-step explanation:
The amplitude of the function of graph y = 2sin(4x - 1) + 3 is 2.
What is the graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
What is function?The function is defined as mathematics expression defines a relationship between one variable and another variable.
What is the amplitude of function?A amplitude of function is defined as periodic variable's amplitude is a measure of its change over a single period. A non-periodic signal's magnitude in relation to a standard value is its amplitude.
Given the function of graph as :
y = 2sin(4x - 1) + 3
Comparing the form asin(bx - c) + d to determine the amplitude, period, phase shift, and vertical shift.
Where a is amplitude , d is vertical shift , c/b is phase shift
Amplitude (a): 2
Period: π/2
Phase Shift (c/b): 1/4 (1/4 to the right)
Vertical Shift (d) : 3
Hence, the amplitude of the function of graph y = 2sin(4x - 1) + 3 is 2.

STEP 1: (1/3 : 1/6) = 2/1 = 2
STEP 2: 3/4 + 2 = 11/4 = 2 3/4 = 2.75
STEP 3: 2.75 (-1/2) = -11/8 = -1 3/8 = -1.375

From previous experience, the owner of an apple orchard knows that the mean weight of Gala apples is 140 grams. There has been more precipitation than usual this year. The owner believes the weights of the apples will be heavier than usual and therefore the crop will be more profitable. This will allow the owner to expand the orchard. The owner takes a random sample of 30 apples and records their mean weight. What is the consequence of a Type I error in this situation?
The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually greater than 140 grams.
The owner believes the crop will not be more profitable and does not expand the orchard when the true mean weight of the apples is actually greater than 140 grams.
The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually not greater than 140 grams.
The owner believes the crop will not be more profitable and does not expand the orchard when the true mean weight of the apples is actually not greater than 140 grams.
Answer:
C, The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually not greater than 140 grams.
Step-by-step explanation:
Using error concepts, it is found that the consequence of a Type I error in this situation in this situation is given by:
The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually not greater than 140 grams.
What are the hypotheses test?At the null hypotheses, it is tested if the weights are not heavier, that is:
[tex]H_0: \mu = 140[/tex]
At the alternative hypotheses, it is tested if they are heavier, that is:
[tex]H_1: \mu > 140[/tex]
A Type I error is the rejection of a true null hypothesis, that is, concluding that the weights are heavier and more profitable when they are not. Hence the correct option is:
The owner believes the crop will be more profitable and expands the orchard when the true mean weight of the apples is actually not greater than 140 grams.

circumference is the line around the circle
circumference = 3.14 x diameter
c = 3.14 x 4
c = 12.56

You want to build a fence around your triangular pool. How many meters of fence will you need? If necessary, round t
the nearest tenth.
15 m
13 m
a.
b.
C.
d.
35.5 m
7.5 m
56 m
97.5 m
Answer:
35.5m
Explanation:
Find the diagram attached
First you need to get the missing side of the triangular pool using the pythagoras theorem;
Let the missing side be x
x² = 15² - 13²
x² = 225 - 169
x² = 56
x = √56
x = 7.48m
Amount of meter of fence needed is the perimeter of the triangular pool
perimeter of the triangular pool = 15 + 13 + 7.48
perimeter of the triangular pool = 35.48m
perimeter of the triangular pool = 35.5m
Hence the amount of meters of fence needed is 35.5m
