Answer: about 78 mL
Step-by-step explanation:
When you see the liquid in a curved shape, you want to look at the very bottom of the curve. The bottom shows that our answer will be in the 70 mL, but close to 80. If you look at the lines in between, we can see that there are 5 lines, meaning each line represents 2 mL. Now, we count up and reach 78 mL.

How many solutions does the system have?
Answers
Answer: A
Step-by-step explanation:
There are 2 ways to solve this problem.
Solution 1:
Since we are given two equations, we set them equal to each other to find where they intersect, the solution.
3x+3=-2x+3 [combine like terms]
5x=0 [divide both sides by 5]
x=0
Now that we have x=0, we can plug it into either equation to find the point of intersection.
y=3(0)+3
y=3
We know that the point of intersection is (0,3).
-------------------------------------------------------------------------------------------------------------
Solution 2:
This way of solving the problem doesn't require any calculations. All it requires is an understanding of slope-intercept form equation. From the two equations given, we know that they are linear lines. Linear lines can only intersect once. Knowing this, we know that there can only be exactly one solution.

The value of each digit in a number is known as the place value. The number is 412,630.
What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
Identification of the place value of a digit in a number:
The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths and so onThe tens mean multiply by 10The tenth means the tenth part of that digit which is that digit divided by 10.As per the given statement, the part of the numbers can be written as,
30 ones = 30 × 1 = 302 thousands = 2 × 1,000 = 2,0004hundred thousands = 4 × 100,000 = 400,00060 tens = 60 × 10 = 600100 hundreds = 100 × 100 = 10,000Now, summing up all, we will get the number,
Number = 30 + 2,000 + 400,000 + 600 + 10,000
= 412,630
Hence, the number is 412,630.

The probability that an online student owns a laptop is 0.82 and the probability that a student owns a desktop is 0.65. If the probability that a student owns both is 0.55, find the probability that a student owns a laptop or a desktop.
Answers
Answer:
The probability that a student owns a laptop or a desktop is 92%.
Step-by-step explanation:
We are given that the probability that an online student owns a laptop is 0.82 and the probability that a student owns a desktop is 0.65. The probability that a student owns both is 0.55 .
And we have to find the probability that a student owns a laptop or a desktop.
Let the probability that a student owns a laptop = P(L) = 0.82
The probability that a student owns a desktop = P(D) = 0.65
The probability that a student owns both laptop and desktop = P(L [tex]\bigcap[/tex] D) = 0.55
Now, the probability that a student owns a laptop or a desktop is given by = P(L [tex]\bigcup[/tex] D)
P(L [tex]\bigcup[/tex] D) = P(L) + P(D) - P(L [tex]\bigcap[/tex] D)
= 0.82 + 0.65 - 0.55
= 0.92 or 92%
So, the probability that a student owns a laptop or a desktop is 92%.

(9x - 4x2 + 9) + (-x3 + 4x2 - 3)
Answers
Answer:
The solution to the given expression is -x³ + 9x + 6
Step-by-step explanation:
(9x - 4x² + 9) + (-x³ + 4x² - 3)
Since there is a positive sign in front of the second parentheses, then the terms inside will stay the same.
9x - 4x² + 9 - x³ + 4x² - 3
Group terms together that are alike. Also known as like terms.
-x³ + (-4x² + 4x²) + 9x + (9 - 3)'
Combine like terms.
-x³ + 9x + 6
Answer:
- [tex]x^{3\\}[/tex] + 9x + 6
Step-by-step explanation:
First, you need to combine like terms. Like terms, when dealing with exponents can be categorized by their powers.
hIn this case, 9x stands alone, because there is no other coefficient with the power of just x.
9x
Next, we can look at the -4x^2. The other similar coefficient is + 4x^2. We can combine both of those, which will equal out to 0.
Next, you have 9. It can be combined with -3, since none of them have an exponent attached. It will equal 6
9x + 6
We also have a -x^3 left over. There is no like term to combine with it, so we can leave it as is.
Our problem now looks like
9x + 6 - [tex]x^{3}[/tex]
You can rearrange them in the proper order, so it will look like,
- [tex]x^{3}[/tex] + 9x + 6.
And there you have it!

In the question the claim whether the promotional campaign actually increased the proportion of tourists visiting the museum is given which is formulated as alternative hypothesis.
So when we formulate the alternative hypothesis as Ha : p> 0.75 the null hypothesis is H0 p ≤ 0.75
Where p is the probability = 75% = 75/100 = 0.75

Answers
Answer:
y = 5/4x -11
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b
where m is the slope and b is the y intercept
y = 5/4 x + b
Substitute the point into the line
-1 = 5/4(8) +b
-1 =10 +b
Subtract 10 from each side
-11 = b
y = 5/4x -11
Answer:
[tex]\huge \boxed{y=\frac{5}{4} x-11}[/tex]
Step-by-step explanation:
The slope-intercept form of a line is written as,
[tex]y=mx+b \\ \\ \\ \sf m= slope \\ \\ b=y -intercept[/tex]
The slope is given.
[tex]\displaystyle y=\frac{5}{4} x+b[/tex]
The line passes through the point (8, -1).

At the beginning of the months, a consumer had $437.52 of in his bank account. During he made deposits of $256 and $217.14 of $80 and write checks of $115.98 and $108.90 - What balance left?
Answers
Question:
At the beginning of the months, a consumer had $437.52 of in his bank account. During which he made deposits of $80, $256 and $217.14 and write checks of $115.98 and $108.90 - What balance left?
Answer:
The customer's balance is $765.78
Step-by-step explanation:
Given
Start Amount = $437.52
Deposits = $80, $256 and $217.14
Withdrawals (Checks) = $115.98 and $108.90
Required
Determine his balance
We start by calculating the total deposits made by the customer
[tex]Total\ Deposits = \$80 + \$256 + \$217.14[/tex]
[tex]Total\ Deposits = \$553.14[/tex]
Next, we calculate the total withdrawals (checks)
[tex]Total\ Withdrawals = \$115.98 + \$108.90[/tex]
[tex]Total\ Withdrawals = \$224.88[/tex]
At this point, we can now calculate the customer's balance as follows;
[tex]Balance =Start\ Amount + Total\ Deposits - Total\ Withdrawals[/tex]
[tex]Balance = \$437.52+ \$553.14 -\$224.88[/tex]
[tex]Balance = \$765.78[/tex]
Hence, the customer's balance is $765.78
The balance left in the consumer's account is $765.78.
The amount of money in the consumer's account increases with the deposits made and reduces when she writes checks.
The total value of the deposits have to be determined first.
Total value of the deposits = $256 + $217.14 + $80 = $553.14
The value of the checks written has to be determined
$115.98 + $108.90 = $224.88
Add the value of deposit, subtract the value of checks from the beginning balance
$437.52 + $553.14 - $224.88 = $765.78
