Step-by-step explanation:
the pattern is
y is 5 times x plus 2
y=5x+2
The solution is, y=5x+2, an equation that shows the relationship between the number of students photographed, x, and the total number of pictures on the memory card, y.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
here, we have,
She took 2 pictures to check that everything is working properly.
Now that it's picture day, she expects to take 5 pictures of each student.
now, we get,
the pattern is
y is 5 times x plus 2

Help me with this question
Answer:
The answer is y=-x+9.
The first thing to do is find where the line intercepts the y-axis, which is at positive 9 so you'll add a +9 to the end of your equation. Next you find the slope and since it's going down left to right, you know it is a negative. Now slope is found by change in y divided by change in x. And since both change and y and change in x are both 1, 1/1 is 1. And since you know it's negative that means the slope is -x. Altogether you get y= -x+9
Jack is paid £2400 a month.
He spends half his money on rent,
He spends the rest on food, bills and savings in the ratio 3:5:4
How much does he spend on bills?
(I really need help with this) - TYSM if anyone is able to help) :)
Answer:
300+400+500=1200
Step-by-step explanation:
given total paid $2400
spend $1200 on a rent (half of his paid)
so rest he spend as a ratio of 3:4:5=1200
let x as a amount he using to pays rest of the bills so
3x+4x+5x=1200
12x=1200
x=1200/12
x=100
so he spends 3x=300
4x=400
5x=500

Use the definition of the derivative to differentiate v=4/2 pie r^3

[tex]\displaystyle \frac{dV}{dr} = \lim_{h\to0} \frac{2\pi(r+h)^3-2\pi r^3}{h}[/tex]

[tex]\displaystyle \frac{dV}{dr} = 2\pi \lim_{h\to0} \frac{3r^2h+3rh^2+h^3}{h}[/tex]
[tex]\displaystyle \frac{dV}{dr} = 2\pi \lim_{h\to0} (3r^2+3rh+h^2)[/tex]

Solve (x-4)^2=5
answer: (x=5+√4
Answer:
x = 4 + sqrt 5
x = 4 - sqrt 5
Step-by-step explanation:
(X-4)^2 = 5
X - 4 = + - sqrt 5
X = 4 + sqrt 5 and
X = 4 - sqrt 5
Answer:
Step-by-step explanation:
Take the square root of each side of the equation to set up the solution for x
[tex](x-4)^{2*\frac{1}{2} } =[/tex] ±[tex]\sqrt{5}[/tex]
Remove the perfect root factor x - 4 under the radical to solve for x.
x - 4 = ±[tex]\sqrt{5}[/tex]
The complete solution is the result of both the positive and negative portions of the solution.
First, use the positive value of the ± to find the first solution.
[tex]x-4=\sqrt{5}[/tex]
Add 4 to both sides of the equation.
[tex]x=\sqrt{5} +4[/tex]
Next, use the negative value of the ± to find the second solution.
[tex]x-4=-\sqrt{5}[/tex]
Add 4 to both sides of the equation.
[tex]x=-\sqrt{5} +4[/tex]
The complete solution is the result of both the positive and negative portions of the solution.
[tex]x=\sqrt{5} +4,-\sqrt{5} +4[/tex]

Pls help ive been stuck on this for hours
Answer:
the correct choice is marked
Step-by-step explanation:
The lengths will form a right triangle if the squares of the two shortest legs total the square of the longest. The square of a root is the number under the radical, so you're looking to see if the two smallest numbers under the radicals total the largest number under the radical.
A: 22 +88 = 110 . . . . . a right triangle
B: 66 +99 = 165 ≠ 176 . . . . an obtuse triangle
C: 22 +110 = 132 ≠ 121 . . . . an acute triangle
D: 66 +77 = 143 ≠ 154 . . . . an obtuse triangle
_____
Additional comment
The largest angle is opposite the longest side. If the longest side is too long for the triangle to be a right triangle, then the opposite angle is larger than 90°, and the triangle is obtuse. If the longest side is too short for a right triangle, then the triangle is acute.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as C
Now , the value of C is
The selling price of the article is given as $440, and we know that the shopkeeper incurs a loss of 12% on the sale
Selling price = Cost price - Loss
Substituting the given values, we get
$440 = C - 0.12C
Simplifying this equation, we get:
$440 = 0.88C
Dividing both sides by 0.88, we get:
C = $500
Hence , the cost price of the article is $500

Answer:
8 + (-3) = 5
Step-by-step explanation:
A number line offers a suitable model. +8 is represented by a segment extending from 0 to 8. -3 is represented by a segment extending from 0 to -3. The addition of those numbers is modeled by placing those segments end-to-end. In the attachment, we have shown -3 placed so it starts at the end of +8. The other end of -3 lies at the sum: 5.
8 + (-3) = 5
I grew up on a pig farm. We raised baby pink pigs from birth to 8 weeks old. A 90% confidence interval is calculated for a sample of weights of 135 randomly selected 8-week old pigs. The resulting confidence interval is 75 to 90 pounds. Will the sample mean weight, from this random sample of 135 pigs, fall within the confidence interval?
a. yes
b. no
c. maybe
Answer:
A
Step-by-step explanation:
3 4 5 6
The sample mean weight, from this random sample of 135 pigs, fall within the confidence interval. (Option A: yes)
How to find the confidence interval for large samples (sample size > 30)?Suppose that we have:
Sample size n > 30Sample mean = [tex]\overline{x}[/tex]Sample standard deviation = [tex]s[/tex]Population standard deviation = [tex]\sigma[/tex]Level of significance = [tex]\alpha[/tex]Then the confidence interval is obtained as
Case 1: Population standard deviation is known[tex]\overline{x} \pm Z_{\alpha /2}\dfrac{\sigma}{\sqrt{n}}[/tex]
Case 2: Population standard deviation is unknown.[tex]\overline{x} \pm Z_{\alpha /2}\dfrac{s}{\sqrt{n}}[/tex]
For this case, we work with sample standard deviation(you can choose even population standard deviation, it won't matter as both are not given here).
We're provided that:
Sample size = n = 135Confidence interval is of 90%, therefore, Level of significance = [tex]\alpha[/tex] = 100 - 90% = 10% = 10/100 = 0.1 (converted percent to decimal)The critical value of Z at 0.1 level of significance is [tex]\pm 1.645[/tex]Confidence interval's limits = 75 (lower limit) and 90(upper limit) (in pounds)Sample mean = [tex]\overline{x}[/tex]Sample standard deviation = [tex]s[/tex]Since the formula for limits of confidence interval is:
[tex]\overline{x} \pm Z_{\alpha /2}\dfrac{s}{\sqrt{n}} = \overline{x} \pm 1.645\dfrac{s}{\sqrt{135}}[/tex]
That has:
[tex]\text{Lower limit} = 75 = \overline{x} - 1.645\dfrac{s}{\sqrt{135}}\\\\\text{Upper limit} = 90 = \overline{x} +1.645\dfrac{s}{\sqrt{135}}\\\\[/tex]
Thus, we get:
Adding both the equations, we get:
[tex]165 = 2\overline{x}\\\\\overline{x} = 82.5 \: \rm pounds[/tex]
That is between 75 and 90 pounds.
Thus, the sample mean weight, from this random sample of 135 pigs, fall within the confidence interval. (Option A: yes)
