Answer:
3.68$Step-by-step explanation:
If 5 apples cost $1.15, find the cost of 16 apples
we can solve with an equation5 : 1.15 = 16 : x
x = 1.15 * 16 : 5
x = 18.04 : 5
x = 3.68
check
5 : 1.15 = 16 : 3.68

A multiple-choice examination has 10 questions, each with four possible answers, only one of which is correct. Suppose that one of the students who takes the examination answers each of the questions with an independent random guess. What is the probability that he answers at least six questions correctly?
Answer:
[tex]0.0197277[/tex]
Step-by-step explanation:
Consider the random variable X
Where X denotes the number of (success/having a correct answer)
in 10 identical and independent trials .
then
X follows the Binomial distribution with parameters
10 and p = p(success) = 1/4
[tex]p\left( X\geq 6\right) =\sum^{10}_{k=6} p\left( X=k\right)[/tex]
[tex]=\sum^{10}_{k=6} C^{k}_{10}\left( \frac{1}{4} \right)^{k} \left( \frac{3}{4} \right)^{10-k}[/tex]
[tex]=\frac{20686}{2^{20}} \\= 0.0197277[/tex]
Given g(x)=^3√x+6, on what interval is the function negative?
A (-∞, -6)
B (-∞, 6)
C (-6, ∞)
D (6, ∞)
The interval which the function is negative is (-∞, -6)
How to determine the interval?The equation of the function is given as:
[tex]g(x) = \sqrt[3]{x + 6}[/tex]
When the function is negative.
It means that g(x) is less than 0
i.e. g(x) < 0
So, we have:
[tex]\sqrt[3]{x + 6} < 0[/tex]
Take the cube of both sides
x + 6 < 0
Subtract 6 from both sides
x < -6
The above represents a value from negative infinity to -6
i.e. (-∞, -6)
Hence, the interval which the function is negative is (-∞, -6)

[tex]\huge\boxed{\bf\:2\sqrt{5} \:\: units }[/tex]
Step-by-step explanation:
We have a figure given in the shape of a square with a diagonal (x) passing from one edge to another. We need to find the measure of its diagonal if the side of the square is [tex]\sqrt{10}[/tex] units.
We know that, a square has all equal sides. Then, all the sides of the square will be equal to [tex]\sqrt{10}[/tex] units.
Now, let's find the diagonal.
To find the diagonal of a sqaure from one of its sides, we need to know the formula ⟶ Diagonal = side [tex]\bf\:\sqrt{2}[/tex].
By using this formula,
[tex]Diagonal (x)\\= side *\sqrt{2} \\= \sqrt{10} *\sqrt{2}\\ = \sqrt{5*2*2} \\= \boxed{\bf\:2\sqrt{5} \:units}[/tex]
→ The diagonal of the square = 2√5 units.

In January, Joanna deposited $250
into her savings account. In
February, she deposited an
additional $100. If her account has
an APR of 6% compounded monthly,
how much interest did Joanna earn
in the first two months?
The interest that Joanna earned in the first two months is $4.26.
What is the interest earned?Interest earned in the first month = future value - amount deposited.
Future value = amount deposited x (1 + monthly interest)
Monthly interest = 6/12 - 0.5% = $252.50
Interest = $252.50 = 250 = $2.50
Interest earned in the second monthly = future value of the first month + amount deposited x (1.005)
(252.50 + 100) x 1.005 = 354.26
Interest = 354.26 = 352.50 = $1.76
Total interest = $1.76 + $2.50 = $4.26

(2x² - 3x) / 7 is the quotient of the given division.
What is simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
To divide by a fraction, we can multiply by its reciprocal. So to simplify the expression:
((2x-3)/x ) / (7/x²)
We can multiply the numerator by the reciprocal of the denominator:
((2x-3)/x ) * (x²/7)
Simplifying this expression, we can cancel out the common factor of x in the numerator and denominator:
(2x-3) * (x/7)
Expanding the product:
(2x² - 3x) / 7
Therefore, the quotient of ((2x-3)/x ) / (7/x^2) is (2x² - 3x) / 7.

(8 kg 300 g 120 mg) − (3 kg 500 g 480 mg) 4 kg 799 g 640 mg
The value of (8 kg 300 g 120 mg) − (3 kg 500 g 480 mg) is; 4 kg 799 g 640 mg
How to carry out Unit Conversions?We want to find the value of;
(8 kg 300 g 120 mg) − (3 kg 500 g 480 mg)
First of all, let us convert all units to kg as;
120 mg = 0.00012 kg
300 g = 0.3 kg
Thus;
8 kg 300 g 120 mg = 8 + 0.3 + 0.00012 = 8.30012 kg
Similarly, converting the second expression;
480 mg = 0.00048 kg
500 g = 0.5 kg
Thus;
3 kg 500 g 480 mg = 3 + 0.5 + 0.00048 = 3.50048 kg
Thus, we have;
8.30012 kg - 3.50048 kg = 4.77964 kg
Breaking down this gives;
4 kg 799 g 640 mg
