A woman bought some large frames for $13 each and some small frames for $5 each at a closeout sale. If she bought 12 frames for $92, find how many of each type she bought.
Answer:
4 of the large frame and 8 of the small frame.
Step-by-step explanation:
92= 13y+ 5x
4* 13= 52
8* 5= 40
40+52= 92
8+4=12

Answer:
The mean of tree heights at Yard Works is 8 feet. The mean of tree heights at The Grow Station is 9 feet. The mean absolute deviations of the tree heights at both yards is 2.
Answer:
The heights, in feet, of the trees for sale at two nurseries are shown below.
Yard Works: 7, 9, 7, 12, 5
The Grow Station: 9, 11, 6, 12, 7
Which statements are true regarding the measures of center and variability of these data sets? Select three choices.
________________________________________________________
1 The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
2 The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.
3 The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
4 The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.
5 The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.
Step-by-step explanation:
Yard works has...
mean=8
median=7
mode=7
range=11
because in order it is 5 7 7 9 12
(5+7+7+9+12)/5=8
5 7( 7 )9 12 is the median
and seven occurs the most
and with this logic...
THE GROWSTATION has a
mean=9
median=9
mode=n/a
range=6
_______________________________________
YEA) The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
YEA) The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.
YEA) The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.
The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.

There are 10 students in a class:7 boys and 3 girls. If the teacher picks a group of 4 at random what is the probability that everyone in the group is a boy
Answer:
Step-by-step explanation:
Probability the first pick is a girl: 7/10
Probability the second pick is a girl: 6/9
Probability the third pick is a girl: 5/8
Probability of picking 3 girls:
7/10 * 6/9 * 5/8 =
= (7 * 6 * 5)/(10 * 9 * 8)
= (7 * 1 * 1)/(2 * 3 * 4)

What are the ratios for SIN A and COS A
Answer:
A
Step-by-step explanation:
A good trick for trigonometric functions is to remember SOHCAHTOA:
Sin=Opposite over Hypotenuse
Cos=Adjacent over Hypotenuse
Tan=Opposite over Adjacent
The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.
So in this case, the sin of angle A (opposite over hypotenuse) would be [tex]\frac{24}{26}[/tex] and cos A (adjacent over hypotenuse) would be [tex]\frac{10}{26}[/tex].
I hope this helps!
Given the equation 8x - 2y = 4, what is the value of
slope (m) and the value of y-intercept (b)
Answer:
slope (m) = 4
y-intercept (b) = -2
Step-by-step explanation:
Identify the best first step in solving the linear equation: x+12=10
add 12 to both sides of the equation
convert the equation to 12x=10
divide both sides of the equation by 12
subtract 12 from both sides of the equation

Me. Watson is making 34.6 fluid once's of red paint and 18.6 fluid ounces of yellow paint to make orange paint. How many 3.5- fluid once jars can she fill?
Answer: She can fill about 15 3.5- fluid once jars.
Step-by-step explanation:
Given:
Quantity of red paint = 34.6 fluid ounces
Quantity of yellow paint = 18.6 fluid ounces
Total quantity of orange color = (Quantity of red paint )+(Quantity of yellow paint )
= (34.6+18.6) fluid ounces
= 53.2 fluid ounces
Number of 3.5- fluid ounce jars she can fill = (Total quantity of orange color) ÷ 3.5
= 53.2÷3.5 = 15 (approx)
Hence, She can fill about 15 3.5- fluid once jars.

Answer:
[tex]y = -\frac{1}{4}x - 2[/tex]
Step-by-step explanation:
i'm not sure if you're trying to find the equation of the line ?? but i'll assume that's the case and find the slope-intercept form equation of the line.
slope intercept form is [tex]y = mx + b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept. since the slope is already identified, you can plug in [tex]-\frac{1}{4}[/tex] for [tex]m[/tex].
[tex]y = mx + b[/tex] ⇒ [tex]y = -\frac{1}{4}x+b[/tex]plug in the [tex]x[/tex] and [tex]y[/tex] values from the coordinate pair that passes through the line, which is (-4, -1). you can start with either [tex]x[/tex] or [tex]y[/tex], but i'm going to start with [tex]x[/tex].
first, plug in [tex]-4[/tex] for [tex]x[/tex].
[tex]y = -\frac{1}{4}x+b[/tex] ⇒ [tex]y = -\frac{1}{4}(-4)+b[/tex]now plug in [tex]-1[/tex] for [tex]y[/tex].
[tex]y = -\frac{1}{4}(-4)+b[/tex] ⇒ [tex]-1 = -\frac{1}{4}(-4)+b[/tex]after plugging in all of the given values, the equation is now [tex]-1 = -\frac{1}{4}(-4)+b[/tex], in which you need to solve for [tex]b[/tex].
now it's time to solve! begin by multiplying [tex]-\frac{1}{4}(-4)[/tex] in order to simplify the right side of the equation.
[tex]-\frac{1}{4}(-4) = 1[/tex]you now have [tex]-1 = 1 + b[/tex]. subtract 1 from both sides of the equation. on the right side, it cancels itself out, leaving you with [tex]b[/tex]. on the left side of the equation, you now have [tex]-1 - 1[/tex], which equals [tex]-2[/tex].
therefore [tex]-2 = b[/tex], or [tex]b = -2[/tex].
now that you've solved for your [tex]b[/tex] value, plug it into your initial slope-intercept form equation!
[tex]y = -\frac{1}{4}x + b[/tex] ⇒ [tex]y = -\frac{1}{4}x - 2[/tex]if you want to check to make sure that the values are correct, plug (-4, -1) into your completed slope-intercept form equation. as you did in the beginning, plug in [tex]-4[/tex] for [tex]x[/tex] and [tex]-1[/tex] for [tex]y[/tex].
[tex]y = -\frac{1}{4}x - 2[/tex] ⇒ [tex]-1 = -\frac{1}{4}(-4) - 2[/tex]begin simplifying by multiplying [tex]-\frac{1}{4}(-4)[/tex].
[tex]-1 = -\frac{1}{4}(-4) - 2[/tex] ⇒ [tex]-1 = 1 - 2[/tex]subtract [tex]1 - 2[/tex].
[tex]-1 = 1 - 2[/tex] ⇒ [tex]-1 = -1[/tex]since both sides of the equation are equal, that means your [tex]b[/tex] value of [tex]-2[/tex] is correct because it makes the equation true!
aaaand there you go! i hope this helps. have a great day! <3

What does it mean for the relationship when there is a positive correlation between the two variables?
Answer: Positive correlation is a relationship between two variables in which both variables move in tandem—that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases
Step-by-step explanation:
Answer:
Step-by-step explanation:
Positive Correlation is the positive relationship between two variables wherein the movements of variables are positively linked and therefore, if one variable goes up and the other variable also goes up, and vice-versa.

MATH HELP!!! MARKING BRAILIESTT
Answer:
y = 3x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 12 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes , then
y = 3x + c ← is the partial equation
To find c substitute (1, - 2 ) into the partial equation
- 2 = 3 + c ⇒ c = - 2 - 3 = - 5
y = 3x - 5 ← equation of parallel line
