11. The numbers 4 through 14 are placed in a bowl and drawn at random then replaced after being drawn. Is it likely or unlikely you will draw a number less than 7?
Answer:
Unlikely
Step-by-step explanation:
In a pool 4-14 you have the numbers: 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14. So there is only three numbers under 7 in this scenario.
What is the slope of the line that passes through the points (-3, -9)(−3,−9) and (22, -4) ?(22,−4)? Write your answer in simplest form.
Answer:
1/5
Step-by-step explanation:
Equation: [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
Points: (-3, -9) and (22, -4)
[tex]y_{2}[/tex] is the second y point that shows up on the question, basically go by order. So it's -4
[tex]y_{1}[/tex] is -9, because again, in order of which coordinates pop-up first in the question
[tex]x_{2}[/tex] is 22, [tex]x_{1}[/tex] is -3
Now input into the equation, to make it easier we'll split the fraction into 2 equations:
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex] = [tex]y_{2} - y_{1}[/tex] and [tex]x_{2} - x_{1}[/tex], we'll put them back in a fraction later
[tex]y_{2} - y_{1}[/tex] = -4 - (-9) = -4 + 9 = 5
[tex]x_{2} - x_{1}[/tex] = 22 - (-3) = 22 + 3 = 25
now put it in the fraction, remember y on top x on the bottom:
5/25, simplify, 1/5

Answer:
The 2nd one 1.96x + .69 < = 3
Step-by-step explanation:
I'm in algebra so I get this.
Basically it's $1.96 per pound of potatoes and "x" represents the amount of potatoes. So essentially you're multiplying 1.96 times how many pounds of potatoes there are. Than it says they only bought 1 pack of cookies and 1 pack is $0.69 so add that to your equation. And we know we only have $3 so that's our max, the most we can spend. So whatever $1.96 and $0.69 add up too has to be less than or equal too $3. And that's it!
If u marked me as brainliest that would be greatly appreciated :D
I need this answered ASAP !!!! Right answers only
The ratio to make a batch of cookies is 2 cups milk and 5 cups chocolate chips. Double the recipe.
9514 1404 393
Answer:
4 cups milk; 10 cups chocolate chips
Step-by-step explanation:
To double the recipe, multiply each of the quantities by 2.
2 × 2 cups milk = 4 cups milk
2 × 5 cups chocolate chips = 10 cups chocolate chips
Evaluate 3x(x-2)/2x-1 when x=0
Answer:
The answer is zero, because the entire equation is being multiplied by zero. The only way that will give you non-zero value is if the denominator in the fraction came to zero as well, but in this case it does not.
Step-by-step explanation:
[tex]3x\frac{x - 2}{2x - 1} \\3(0)\frac{0-2}{2(0) - 1}\\0[/tex]
Which is the smaller number: -5 or -15?
Answer:
-15
Step-by-step explanation:
-15 is smaller because it is a negative number. -5 is closer to 0. -15 is farther away from 0.
Which of the graphs below represents the soltuion set for d - 4 > -3?
Answer:
Answer choice "C".
Step-by-step explanation:
In this question, we have to find the graph that fits the inequality.
First, we need to simplify the inequality.
Solve:
d - 4 > -3
Add 4 to both sides.
d > 1
Now, we can find which graph fits the inequality.
We know that the graph has to start at 1, so we can already eliminate answer choices A, B, and D.
General rule of them is that the direction of the arrow is the opposite direction of the inequality sign.
If the inequality is ">", the arrow on the graph should be pointed rightward (→)
If the inequality is "<", the arrow on the graph should be pointed leftward (←)
Since out inequality sign is ">", the arrow has to be pointing rightward, therefore making answer choice "C" the right answer.

Step-by-step explanation:
please I need help show work pls
Answer: A
Step-by-step explanation:
If you write down the points you’ll get:
(2,6) & (3,9) & (5,15)
Next apply the expression which in this case:
A) y =3x
Now insert the numbers
1) (2,6) => 6=3(2)
2) (3,9) => 9=3(3)
3) (5,15) => 15=3(5)
So, A is correct.
Edit: Forgot to mention about the numbers placement.
(x,y) so numbers on the left is x while those on the right is y

Answer:
x>-4
Step-by-step explanation:
4x-2 =3x + 35 solve it
Answer:
x=37
Step-by-step explanation:
4x-2=3x+35 Add 2 to both sides.
+2 +2
4x=3x+37 Subtract 3x on both sides.
-3x -3x
x=37

What are the coefficients in the algebraic expression
Jean's bedroom is 12 feet by 12 feet. She has chosen a carpet which costs $28.10 per square yard. This includes installation.
Answer:
$449.60
Step-by-step explanation:
12 x 12 = 144, her room is 144 square feet. One yard is three feet, making a square yard equal to 9 square feet. 144 divided by 9 is 16 square yards. Now we do 16 times the installation cost $28.10. So 16 x 28.10 = 449.6, or $449.60.
I hope this helps!
Based on a sample of 100 employees a 95% confidence interval is calculated for the mean age of all employees at a large firm. The interval is (34.5 years, 47.2 years).
A. What was the sample mean?
B. Find the margin of error?
C. Find the critical value tc for:
a. a 90% confidence level when the sample size is 22.
b. an 80% confidence level when the sample size is 49.
Answer:
a
[tex]\= x = 40.85[/tex]
b
[tex]E = 5.85[/tex]
Ca
[tex]t_c = 2.08 [/tex]
Cb
[tex] t_c = 1.282 [/tex]
Explanation:
From the question we are told that
The sample size is n = 100
The upper limit of the 95% confidence interval is b = 47.2 years
The lower limit of the 95% confidence interval is a = 34.5 years
Generally the sample mean is mathematically represented as
[tex]\= x = \frac{a + b }{2}[/tex]
=> [tex]\= x = \frac{47.2 + 34.5 }{2}[/tex]
=> [tex]\= x = 40.85[/tex]
Generally the margin of error is mathematically represented as
[tex]E = \frac{b- a }{ 2}[/tex]
=> [tex]E = \frac{47.2- 34.5 }{ 2}[/tex]
=> [tex]E = 5.85[/tex]
Considering question C a
From the question we are told the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 90 ) \%[/tex]
=> [tex]\alpha = 0.10[/tex]
The sample size is n = 22
Given that the sample size is not sufficient enough i.e [tex]n < 30[/tex] we will make use of the student t distribution table
Generally the degree of freedom is mathematically represented as
[tex]df = n- 1[/tex]
=> [tex]df = 22 - 1[/tex]
=> [tex]df = 21[/tex]
Generally from the student t distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of 21 is
[tex]t_c =t_{\frac{\alpha }{2} , 21 } = 2.08 [/tex]
Considering question C b
From the question we are told the confidence level is 80% , hence the level of significance is
[tex]\alpha = (100 - 80 ) \%[/tex]
=> [tex]\alpha = 0.20[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex] t_c =Z_{\frac{\alpha }{2} } = 1.282 [/tex]
Divide: 1.98 divided by 0.09

B. X-1+N83 orx= 1-iN88
C. x- 1+9/ or x 1-9;
D. X- 2+9i or x- 2-9/
Answer:
x = 1+√83 i/6 and 1-√83 i/6
Step-by-step explanation:
Given the quadratic expression;
3x^2-x+7 =0
Using the general foemula to find x
x = -b±√b²-4ac/2a
From the equation
a = 3, b = -1 and c = 7
Substitute
x = -(-1)±√(1)²-4(3)(7)/2(3)
x = 1±√1-84/6
x = 1±√-83/6
x = 1±√83 i/6
x = 1+√83 i/6 and 1-√83 i/6

Write the equation of a line that is parallel to y=4 and passes through the point (-2,7)
Answer:
Y= 2X+8
Step-by-step explanation:
Compare the given line with y=mx+c will give the slope of the parallel line as 2. Equation of new line in point slope form is y-y1 = m(x-x1). So y-4 = 2 (x+2) will give you Y= 2X+8

Answer:
1. Lin raised $40
2. Jada raised $20
3. Andre raised $60
Step-by-step explanation:
1. It says Lin raised 100% of her goal and the goal was $40 which means that she earned $40
2. For this one it says Jada raised only 50% of her goal. To solve this one you just take half of 40 since it says she raised only 50% of her goal which gets you 20
3. For this one you just have to do some adding. The first part of the problem you take away the 50% of the 150% for a minute and that just leaves 100% which is a total of 40$ you then just look at the 50% by itself which is 20$. Then you take 40 and add the 20 to it which gets you a total of 60$
