Answer:
0.512 ; - 0.538
Step-by-step explanation:
Using the standard linear regression relation :
y = bx + c
b slope ; c = intercept ; y = dependent ; x = independent variable.
For finalist between 2004 - 2014 ;
y = 0.024x - 0.328
x = 35
y = 0.024(35) - 0.328
y = 0.512
For finalist between 1990 - 2014 ; with 14 winners ; change in daily circulation :
y = -0.015x - 0.328
x = 14.
y = -0.015(14) - 0.328
y = - 0.538

Solve for x.
2x + 15
3x - 20
x = [?]
Answer:
x= 7
3x-20
2x+15
you would add 3x+2x equals 5x and 20 +15= 35
5x+35
35 divided by 5 is 7 and then on the 5x divide by 5 and leaves x=7
Answer:
35
Step-by-step explanation:
Angles 2x + 15 and 3x - 20 are adjacent angles.
Adjacent angles are equal.
3x - 20 = 2x + 15
3x - 2x = 15 + 20
x = 35
Write at least three expressions that are equivalent to 3(2x - 5)
Answer:
6x - 15
6x - (5 · 3)
(3 · 2x) - 15
So, for #1, we can just simplify 3(2x - 5) to get another expression:
3(2x - 5),
6x-15
For the next one, we could make a new equation that equals 6x-15:
(3x)+(3x)+(5 *-3)
Then for the last one, how about rewrite it so all of the values are inversely negated?
3(2x - 5),
-3(-2x +5)
There are 10 bags of cereal in a pantry. Each serving of cereal is 1/8 of a bag.
How many servings of cereal are there in the bags in the pantry?
Answer:
80 servings
Step-by-step explanation:
there is 8 serving per bag
Answer:
80
Step-by-step explanation:
Let servings be s and the bag be b
s = 1/8 b
multiply both sides by 8
8s = b
For 10 bags, it will be 10*8s = 80s which is 80 servings.
Felipe buys candy that costs $7 per pound. He will spend at least $56 on candy. What are the possible numbers of pounds he will buy?
Answer:
x ≥ 8
Step-by-step explanation:
Let x be the number of pounds he buys. As each pound costs 7 dollars and he must spend at least 56 dollars, we have:
7x ≥ 56
x ≥ 8 (divide each side by 7)
Thus, our answer is any number above 8.
There are 35 red marbles, 8 blue marbles, and 7 green marbles in a bag. What is the theoretical probability of randomly drawing a red marble?
○ 35%
○ 25%
○ 42.9%
○ 70%
Answer:
70%
Step-by-step explanation: 35/50 equals 0.7
Answer:
70%
Step-by-step explanation:
The total number of marbles will be 35 + 8 + 7 = 50 marbles in total (all the colors added together). The probability of drawing a red marble will be the number of red marbles divided by the total marbles. This also fits the probability formula of (desired outcomes)/(total number of outcomes. Thus, we have 35 red marbles and 50 marbles in total. So, we get 35/50, which is 70%.
½ cup of sugar, and I only have a ¼ cup scoop and a ⅛ cup scoop. I need at least two different ways I can get ½ cup
2 ways to get to 1/2
Way 1:
Use the 1/4 scoop 2 times
1/4 + 1/4 =2/4
2/4 simplified is 1/2
Way 2:
Use the 1/8 scoop 4 titmes
1/8+1/8+1/8+1/8=4/8
4/8 simplified is 1/2

Answer:
Relation 1: Not a function
Relation 2: Not a function
Relation 3: Function
Relation 4: Not a function
Step-by-step explanation:
Recall: a relation can only be a function if and only if each domain value has only 1 range value mapped to it or related to it. This means that a domain value can only have exactly one range value for the relation to be qualified a function.
✔️Relation 1 is NOT A FUNCTION.
Rationale: Two of the domain values (star and sky) is having more than 1 range value assigned to each.
✔️Relation 2 is NOT A FUNCTION:
Rationale: domain value, 9, has several range values assigned to it.
✔️Relation 3 is A FUNCTION:
Rationale: each domain value do not have more than one range values assigned to it.
✔️Relation 4 IS NOT A FUNCTION:
Rationale: the domain value, 6, has two range values, m and d, assigned to it.

Choose one. 5 points
$68.00
$65.00
$69.00
$60.00
Answer:
$65.00
Step-by-step explanation:
Cost price of shirt after giving discounts is equals to [tex]\$68[/tex].
What is Cost price?" Cost price is defined as the price to be paid at the time of purchase any product."
According to the question,
Initial cost price of shirt [tex]= \$100[/tex]
First discount [tex]= 15\%[/tex]
Discount amount [tex]= 15\%[/tex] of [tex]100[/tex]
[tex]= \frac{15}{100} \times 100\\\\= \$15[/tex]
Cost price after first discount [tex]= 100 - 15[/tex]
[tex]= \$85[/tex]
Second discount [tex]= 20\%[/tex]
Discount amount [tex]= 20\%[/tex] of [tex]85[/tex]
[tex]= \frac{20}{100} \times 85\\\\= \$17[/tex]
Cost price after first discount [tex]= 85 - 17[/tex]
[tex]= \$68[/tex]
Hence, cost price of shirt after giving discounts is equals to [tex]\$68[/tex].

Here it is jaded :):)
Answer:
9.03 = x
Step-by-step explanation:
Since we have the Hypotenuse given and we need to find the value of the adjacent side of the given angle we would use the Cosine Ratio;
Cos(46) = [tex]\frac{x}{13}[/tex]
To solve for "x" we would first have to isolate the "x" all to itself.
To isolate the variable, simply multiply 13 to the both sides of "="
=> Cos(46) * 13 = x
=> 9.03 = x
So you can write the answer in either of the 2 ways mentioned above, if you need a fully simplified answer the second answer would be a better fit. If u just need the Equation the 1st equation would be the better fit.

Answer:
Landon's purchase: p +5g = 17.55Lesley's purchase: 4p +2g = 13.50pretzel: $1.80granola bar: $3.15Step-by-step explanation:
The equation representing either purchase will multiply the number of items by their cost, for each item, and show the total as the cost of the purchase. Here, p is defined as the cost of a pretzel; g is defined as the cost of a granola bar.
Landon's purchase
1 pretzel + 5 bars will cost 1p +5g
That cost is 17.55, so the equation is ...
p +5g = 17.55
Lesley's purchase
4 pretzels + 2 gars will cost 4p +2g
That cost is 13.50, so the equation is ...
4p +2g = 13.50
__
To solve, you can subtract the second equation from 4 times the first:
4(p +5g) -(4p +2g) = 4(17.55) -(13.50)
18g = 56.70 . . . . collect terms
g = 3.15 . . . . . . . . divide by 18
Then the cost of a pretzel can be found using the first equation.
p + 5(3.15) = 17.55
p = 1.80
The cost of a pretzel is $1.80; the cost of a granola bar is $3.15.
5. Ten workers are fencing a 25 m by 28 m stadium. They had finished fencing 95 m.
How many more metres of fence co they need to build?
A. 11 m
C. 148 m
B. 106 m
D. 201 m
Answer:
A. 11 m
Step-by-step explanation:
Given that
the ten workers are fencing 25 m by 28 m
And, they finished the fencing 95 m
We need to find out the number of more meter of fence that could be developed
So,
= (25+25) + (28+28)
= 106 - 95
= 11
Hence, 11 more meters should be build
Therefore the correct option is A.

Line m is mapped onto line n by a dilation centered at the origin with a scale factor of 2. The equation of line m is 3x−2y=63x-2y=63x−2y=6 . Find the equation for line n showing all work for full credit.
9514 1404 393
Answer:
3x -2y = 12
Step-by-step explanation:
The constant in the standard form equation for a line is proportional to the distance of the line from the origin. Dilation by a factor of 2 moves the line to twice its original distance from the origin. The equation of the new line will have the constant 2×6 = 12:
3x -2y = 12
_____
Additional comment
The actual distance of line ax+by=c from the origin is ...
d = |c|/√(a²+b²)
The distance from any point in the plane to the line is ...
d = |ax +by -c|/√(a²+b²)
The previous equation is for the special case of (x, y) = (0, 0), the distance from the origin.

In certain regions of the country, elk can cause damage to agricultural crops by walking through the fields. One strategy designed to limit elk from crossing a field is to surround the field with a fence. Some elk, however, will still be able to bypass the fence. For a period of one month, the number of elk found crossing a sample of fields with a fence was recorded and used to construct the 95 percent confidence interval (2.9,4.4) for the mean number of elk. Assume that the conditions for inference were checked and verified.
Required:
The interval (2.9, 4.4) provides convincing statistical evidence which claims?
Answer:
The mean number of elk to cross all fields protected by fence is equal to 3.65 per month.
Step-by-step explanation:
Given the confidence interval : (2.9,4.4)
Confidence = xbar ± standard Error
To obtain the mean :
We first calculate the standard error :
Standard Error from confidence interval :
(Upper boundary - Lower boundary interval) / 2
(4.4 - 2.9) / 2
1.5 / 2
= 0.75
Hence, the mean can be obtained as :
(Lower boundary + 0.75) or (Upper boundary - 0.75)
Lower boundary + 0.75 = 2.9 + 0.75 = 3.65
Upper boundary - 0.75 = 4.4 - 0.75 = 3.65
