Step-by-step explanation:
Jace bought 4 cookies and 2 brownies from the bakery.
Let x represent the number of cookies and y represent the number of brownies.
Since he bought $9 worth of cookies and brownies. Each cookie costs $0.75 and each brownie costs $3. hence:
0.75x + 3y = 9 (1)
Also, he bought twice as many cookies as brownies, hence:
x = 2y
x - 2y = 0 (2)
Solving equation 1 and 2 simultaneously gives x = 4, y = 2
Hence Jace bought 4 cookies and 2 brownies from the bakery.

The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.Step-by-step explanation:
According to the graph, the line crosses the y-axis at y = 4. Therefore, our y-intercept is 4. Writing it in coordinate point would be (0, 4), as definition of the y-int.

cluster sampling
simple random sampling
stratified random sampling
systematic random sampling
Answer:
Simple random sampling.
Step-by-step explanation:
In this case, the statistics teacher selects a group of students from his class absolutely at random, without taking into account any specific factor when making said selection, rather than absolute chance.
In this way, in the case the teacher performs a simple random sampling with respect to his class, since the selected students do not respond to any specific characteristics that are required for the sample.

which equation below has a slope of 1/4?
Answer:
The answer is 1, 2, and 3 only
Step-by-step explanation:
Math
Way
The equations which have slope 1/4:
ii. (y - 3.5) = 0.25(x - 2.75)
iii. 5x - 20y = 32
What is the equation of line?The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.
The slope-intercept form of a linear equation is y = mx + b, where m is the slope.
I. y = x - 5 is in slope-intercept form, so we can see that its slope is 1.
II. (y - 3.5) = 0.25(x - 2.75) can be rewritten in slope-intercept form as y = 0.25x + 2.1875. Therefore, its slope is 0.25 or 1/4.
III. 5x - 20y = 32 can be rewritten in slope-intercept form as y = (1/4)x - (4/5). Therefore, its slope is 1/4.
IV. 5x + 20y = 32 can be rewritten in slope-intercept form as y = (-1/4)x + (4/5). Therefore, its slope is -1/4.
So, only equations II, and III have a slope of 1/4.

It's the third option because if you put a piece of paper in the corner its a lil more than 90 degrees, so it wouldn't be B (there's a little more white space left). And it obviously wouldn't be A because that's self explanatory, lol.
And you can't make a perfect square in the inside of the angle so that's another way to tell.

If $18,000 is invested at 9% for 15 years. Find the future value if the interest is compounded semi-annually. Please round the answer to the nearest cent (two decimal places) . Enter only the number without $ sign.
Answer:
$67415.73
Step-by-step explanation:
we know that
FV = P(1+r/n)^nt
where FV = future value
P= Present values =$18000
r= rate of interest =9%
n= year. = 15 year
here , the interest is compounded semi-annually
this means n= 30 , r= 4.5%
plugging the value we have
FV = 18000(1.045)^30= $67415.7264= $67415.73
