HURRY PLEASE!!!!!! Boden's account has a principal of $300 and a simple interest rate of 4.4%. Complete the number line. How much money will be in the account after 4 years, assuming Boden does not add or take out any money?
Answer:
$66.00
Step-by-step explanation:
first we need multiply :D I will use the formula I =prt
principal= $500
rate=3.3%
time= 4 years
but we need to convert the percent, 3.3%, to a decimal
3.3%=0.033 or .033
now we multiply !
500 × 0.033 × 4 = 66 = $66.00

The mean room temperature from Monday to Saturday is 25oC and the mean room temperature of Saturday and Sunday is 28oC. if the mean room temperature from Monday to Sunday is 26oC, find the room temperature on Saturday
Answer:
We can conclude that the room temperature on Saturday was 24°C
Step-by-step explanation:
For a set of N values:
{x₁, x₂, ..., xₙ}
The mean of the set is calculated as:
[tex]M = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]
In this case, our set is the temperature of 7 days (so we have 7 elements)
{T₁, T₂, T₃, T₄, T₅, T₆, T₇}
Such that:
T₆ = temperature on Saturday
T₇ = temperature on Sunday.
We know that:
"The mean room temperature from Monday to Saturday is 25°C"
Then:
[tex]\frac{T_1 + T_2 + T_3 + T_4 + T_5 + T_6}{6} = 25 C[/tex]
"the mean room temperature of Saturday and Sunday is 28°C"
[tex]\frac{T_6 + T_7}{2} = 28C[/tex]
"The mean room temperature from Monday to Sunday is 26°C"
[tex]\frac{T_1 + T_2 + T_3 + T_4 + T_5 + T_6 + T_7}{7} = 26 C[/tex]
So we have 3 equations.
Let's rewrite:
T₁ + T₂ + T₃ + T₄ + T₅ = A
Then we can rewrite our equations as:
[tex]\frac{A+ T_6}{6} = 25 C[/tex]
[tex]\frac{T_6 + T_7}{2} = 28C[/tex]
[tex]\frac{A + T_6 + T_7}{7} = 26 C[/tex]
Removing the "Celcius" and multiplying in the 3 equations by the denominator on both sides, we get:
A + T₆ = 6*25
T₆ + T₇ = 2*28
A + T₆ + T₇ = 7*26
We now need to solve that system for T₆
The first step is to isolate one of the variables in one of the equations, (because we want to solve this for T₆ , let's not isolate that one). Let's isolate A in the first one:
A = 6*25 - T₆
A = 150 - T₆
Now we can replace this on the other two equations:
T₆ + T₇ = 2*28
(150 - T₆ ) + T₆ + T₇ = 7*26
Now, let's isolate T₇ in the top equation to get:
T₇ = 2*28 - T₆
T₇ = 56 - T₆
Now we can replace this in the last equation to get:
(150 - T₆ ) + T₆ + (56 - T₆) = 7*26
Now, we can solve this for T₆
150 - T₆ + T₆ + 56 - T₆ = 182
-T₆ = 182 - 150 - 56
-T₆ = -24
T₆ = 24
We can conclude that the room temperature on Saturday was 24°C
what is the solution to 8t - 2 - 9t < 5?
Answer:

Combine like terms
- 2 - t < 5
Add 2 to each side
-2-t+2 < 5+2
-t <7
Multiply each side by -1, remembering to flip the inequality

Probability that the two numbers are multiples of 3 after replacing first
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The odd integers from11 to 22 are
11,13,15,17,19,21
So there are 6 events
Out of these 6 numbers, 2 numbers (15,21) are multiples of 3.
One number out of these 2 numbers can be chosen in 2 ways.
Therefore, favourable number of elementary events = 2.
Required probability =2/6=1/3
Hence 1/3 is the probability that the two numbers are multiples of 3 after replacing first

4x+2=-13 solve for x
Answer:
Solution given
4x+2=-13
subtract each term by 2
4x+2-2=-13-2
divide both side by 4
4x/4=-15/4
we get
x=-15/4
is a required answer.
Let's solve:
[tex]4x+2=−13[/tex]
Step 1: Subtract 2 from both sides.
[tex]4x+2−2=−13−2 \\ 4x = - 15[/tex]
Step 2: Divide both sides by 4.

Explain how
you know you would use sine, cosine or tangent to
solve this. Explain thorougly
C
X
10
B В
Answer:
To solve for x, I would use Cosine.
This is because cosine holds the ratio of adjacent/hypotenuse. Based on the diagram, we can see that HYPOTENUSE = x, so we are solving for x. We know the angle, is 17 degrees. Lastly, we know the triangle leg ADJACENT to the angle is 10 units long. So we would use cosine, implementing the ratio adjacent/hypotenuse. Solving this, we would use cos(17)=10/x. Then our goal is to isolate x, so cos(17)=10/x becomes cos(17)*x=10, we are still trying to isolate x, so, x=10/cos(17). Therefore, our answer x = 10.457 units. cosine would be the best way to go.

X = 11
Step-by-step explanation:
3^(x-7) = 81
Find what exponent makes three into 81
The answer: x = 11
Answer:
x = 11
Step-by-step explanation:
Given
[tex]3^{x-7}[/tex] + 4 = 85 ( subtract 4 from both sides
[tex]3^{x-7}[/tex] = 81
[tex]3^{x-7}[/tex] = [tex]3^{4}[/tex]

x - 7 = 4 ( add 7 to both sides )
x = 11

Answer: Choice D
[tex]\frac{9\sqrt{2}}{2}[/tex]
=============================================
Explanation:
We have a 45-45-90 triangle. If x is the leg length, then y = x*sqrt(2) is the hypotenuse.
Solving for y gets us [tex]x= \frac{y}{\sqrt{2}} = \frac{y\sqrt{2}}{2}[/tex]
In this case, y = 9 is the hypotenuse which then leads to choice D.
------------
Another way to find the answer is to use the pythagorean theorem
a = x and b = x are the two congruent legs
c = 9 is the hypotenuse
Solving a^2+b^2 = c^2, aka x^2+x^2 = 9^2, will lead to [tex]x = \frac{9\sqrt{2}}{2}[/tex]

THE CORRECT ANSWER IS 57 CM³!
The weight of oranges growing in an orchard is normally distributed with a mean weight of 5 oz. and a standard deviation of 0.5 oz. From a batch of 1500 oranges, how many would be expected to weight less than 5 oz., to the nearest whole number?
Answer:
The interval that would represent weights of the middle 95% of all oranges from this orchard is from 5 oz to 7 oz.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 6
Standard deviation = 0.5
Middle 95% of weights:
By the Empirical Rule, within 2 standard deviations of the mean.
6 - 2*0.5 = 5
6 + 2*0.5 = 7
The interval that would represent weights of the middle 95% of all oranges from this orchard is from 5 oz to 7 oz.
how to write a relative frequency
Answer:
To find a relative frequency you need to divide the total number of x in the frequency to the total number. This can be represented as a fraction, decimal, or percent.
Step-by-step explanation:
For example,
The ball landed 3 times out of 40.
3/40 = 7.5%
Step-by-step explanation:
To find the relative frequencies, divide each frequency by the total number of students in the sample–in this case, 20. Relative frequencies can be written as fractions, percents, or decimals. Cumulative relative frequency is the accumulation of the previous relative frequencies.
Example: Your team has won 9 games from a total of 12 games played: the Frequency of winning is 9. the Relative Frequency of winning is 9/12 = 75%
