3 + [2 + 3 X (6 X 3)]
Write the equation of the line passing through the points (2,-5) (3,-1)
Answer:
they give you two points... so use the point slope formula with one on the points
y - y1 = m ( x - x1)
Step-by-step explanation:
find the slope m
m = y2 -y1 / x2-x1
from the given.. x1=2 and y1 = -5
x2 = 3 and y2 = -1 then,
m = -1 -( -5) / 3 - 2
m = 4/1
m = 4
now plug in to the point slope formula either of the points... I'll use the 1st point
y - 2 = 4(x -(-5))
y -2 = 4(x +5)
y -2 = 4x +20
y = 4x +22

A supplier of digital memory cards claims that less than 1% of the cards are defective. In a random sample of600 memory cards, it is found that 3% are defective, but the supplier claims that this is only a sample fluctuation. At the 0.01 level of significance, test the supplier's claim that less than 1% are defective. Use the p-value method.
Answer:
The decision rule is
Fail to reject the null hypothesis
The conclusion is
The is no sufficient evidence to support the claim that the less than 1% of the cards are defective
Step-by-step explanation:
From the question we are told that
The sample size is [tex]n = 600[/tex]
The population proportion of defective samples is p = 0.01
The sample proportion of defective samples is [tex]\^ p = 0.03[/tex]
The level of significance is [tex]\alpha = 0.01[/tex]
The null hypothesis is [tex]H_o : p = 0.01[/tex]
The alternative hypothesis is [tex]H_a: p < 0.01[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{\^ p - p }{ \sqrt{ \frac{p( 1 - p )}{n} } }[/tex]
=> [tex]t = \frac{0.03 - 0.01 }{ \sqrt{ \frac{0.01( 1 - 0.01 )}{600} } }[/tex]
=> [tex]t = 0.00406[/tex]
From the z table the area under the normal curve to the left corresponding to 0.00406 is
[tex]p-value = P(Z < 0.00406 ) = 0.50162[/tex]
comparing the p-valve and the level of significance we see that the
[tex]p-value > \alpha[/tex] hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is
The is no sufficient evidence to support the claim that the less than 1% of the cards are defective

Group of answer choices
75 feet
129 feet
141 feet
27 feet
The distance between a boat and a cliff is 129 feet.
TrigonometryThe trigonometric functions are used to determine the distance and angle in real-life situations.
How to find the distance between a boat and a cliff using trigonometry?Consider the following diagram.
Let the distance between a boat and a cliff be [tex]x[/tex].
[tex]tan25^{o}=\frac{40}{x}[/tex]
[tex]x=\frac{35+25}{tan25}[/tex]

Evaluate each expression. Enter the correct answers in the boxes. (60−6)×(13)3+27÷3= ( 60 − 6 ) × ( 1 3 ) 3 + 27 ÷ 3 = 82÷4×(2+3)−9= 8 2 ÷ 4 × ( 2 + 3 ) − 9 = Ʃ 789+Plus456-Minus123×Multiplied by0.,÷Divided byemptyemptyBackspace=Equals
Answer:
2115
Explanation:
To evaluate the expression (60−6)×(13)3+27÷3 we use BODMAS
BODMAS is an acronym/rule in mathematics that dictates the order we should solve mathematical operations such as the above.
BODMAS stands for bracket first, order or of, division, multiplication, addition and then lastly subtraction
To solve the expression using BODMAS, we solve the brackets first
(60−6)×(13)3+27÷3 =54×39+27/3
Then division
=54×39+9
=2106+9
Then addition
=2106+9=2115
Answer=2115
Item 18 Two times the greater of two consecutive integers is 9 less than three times the lesser integer. What are the integers? Item 18 Two times the greater of two consecutive integers is 9 less than three times the lesser integer. What are the integers?
Answer:
11 and 12
Step-by-step explanation:
Let the consecutive integers be x and x+1
The lesser integer = x
The greater integer = x+1
Two times the greater of two consecutive integers is expressed as;
2(x+1) = 2x+2.
9 less than three times the lesser integer is expressed as;
3x - 9
Equate both expression
2x+2 = 3x - 9
2x-3x = -9-2
-x = -11.
x = 11
The greater integer = x+1 = 11+1 = 12
Hence the integers are 11 and 12

Samuel found the difference of the polynomials. (15x^2+11y^2+8x)-(7x^2+5y^2+2x)= blankx^2+6y^2+6x What value is missing from his solution?
Answer:
Co-efficient of [tex]x^{2}[/tex] is missing.
It should be 8[tex]x^{2}[/tex].
Step-by-step explanation:
Given two polynomials:
1st polynomial: [tex]15x^2+11y^2+8x[/tex]
2nd polynomial: [tex]-7x^2+5y^2+2x[/tex]
To find:
The value in the blank:
[tex](15x^2+11y^2+8x)-(7x^2+5y^2+2x)= \_\_ \ x^2+6y^2+6x[/tex]
Solution:
Here, we have 3 pair of like terms.
2 terms with [tex]x^{2}[/tex], 2 terms with [tex]y^{2}[/tex]and 2 terms with [tex]x[/tex].
Like terms can be subtracted.
Subtracting the terms with [tex]y^{2}[/tex], the coefficients will get subtracted.
[tex]11y^2 - 5y^2 = 6y^2[/tex]
Subtracting the terms with [tex]x[/tex], the coefficients will get subtracted.
[tex]8x -2x=6x[/tex]
Subtracting the terms with [tex]x^{2}[/tex], the coefficients will get subtracted.
[tex]15x^2 - 7x^2 =\bold{8}x^2[/tex]
Therefore, the answer is:
Co-efficient of [tex]x^{2}[/tex] is missing.
It should be 8[tex]x^{2}[/tex].
Write an equation in slope-intercept form of the line that passes through the given point and is
perpendicular to the graph of the given equation.
(5,0); y+1=2(x-3)
Answer:
[tex]y=\frac{-1}{2}x +\frac{5}{2}[/tex]
Step-by-step explanation:
Slope intercept form looks like y=mx+b
The slope (m) needs to be the opposite reciprocal of 2, because the line needs to be perpendicular the given line. Therefore, m = -1/2
We can write the equation in point-slope form first because we're given a point and now we have the slope. The equation would be [tex]y-0=\frac{-1}{2} (x-5)[/tex]
Rewriting, we get [tex]y=\frac{-1}{2}x +\frac{5}{2}[/tex]

Identify each value of x that makes 11 + 2x < 13
Answer:
x < 1
Step-by-step explanation:
This is the answer because:
1) 11 + 2 = 13 and 13 is not less than 13, it is equal to 13. Therefore, x has to equal anything less than 1 because then only inequality statement will be true.
Therefore, the answer is x < 1.
Hope this helps! :D
The value of x that makes 11 + 2x < 13 is x < 1
Given:
11 + 2x < 13
< means less than
11 + 2x < 13
Subtract 11 from both sides11 + 2x - 11 < 13 - 11
2x < 2
divide both sides by 2x < 2/2
x < 1
x less than 1
Therefore, the value of x that makes 11 + 2x < 13 is x < 1
