Answer:
Step-by-step explanation:
Like terms: 10y, -2y, 3x, and x
These are all like terms since they have a similar variable
Simplifying the expressions:
10y + 3x + 10 + x -2y = [(10y + -2y) + (3x + x)] + 10
= 8y + 4x + 10
Like terms: 3x, 4x, y, and -2y
Same as first explanation, terms have a similar variable
3x - y + 4x + 6 - 2y = (3x + 4x) + (-2y - y) + 6
= -3y + 7x + 6
Hope I helped :)
Answer:
Since the null hypothesis is true, finding the significance is a type I error.
The probability of the year I error = level of significance = 0.05.
so, the number of tests that will be incorrectly found significant is computed as follow: 0.05 * 100 = 5
Therefore, 5 tests will be incorrectly found significant given that the null hypothesis is true.
Implicit defferentation
remember that dy/dx y= dy/dx
so
take derivitive of both sides
solve for
minus 2x both sides
divide both sides by 2y
when is the slope equal to
solve for
find where the circle and this line intersects
substitute
for y
times both sides by
sqrt both sides, take positive and negative roots
x=+/-10

<span>The height of Gateway Arch shown on the Missouri quarter is 630 feet or 7,560 inches. Find how many 4 inch stacks of quarters make up the height of the Gateway Arch. If there are 58 quarter in 4 inch stack o, how many quarters high is the arch? </span>
<span>Hence to find how many 4 inch stacks of quarters make up the height of the </span><span>Gateway Arch,
Since the Gateway Arch is 7560 then for every stack is 4 inches to find the stacks all in all, we just have to divide 7560 / 4 = 1890
Then, to find </span><span>how many quarters high is the arch,
58 quarter x 4 inch = 232 quarters high in inches.
