Answer:
5) we get a=6
6) we get c=8
Step-by-step explanation:
The triangles given are similar.
When the triangles are similar, the ratio of corresponding sides are also similar.
5) If c = 12, find a
We will use the ratio
[tex]\frac{30}{12}=\frac{15}{a}[/tex]
Now cross multiply to find value of a
[tex]30*a=12*15\\a=\frac{180}{30}\\a=6\\[/tex]
So, we get a=6
6. If b = 6.4, find c
We will use the ratio
[tex]\frac{30}{c}=\frac{24}{6.4}[/tex]
Now cross multiply to find value of b
[tex]30*6.4=24*c\\c=\frac{192}{24}\\c=8\\[/tex]
So, we get c=8

Answer:
40%
Step-by-step explanation:
Move the period over twice then place the percentage sign where you moved the period to
Answer:
40%
multiply both numerator and denominator by 100. You do this to find a equivalent fraction having 100 as the denominator. The fraction is 40 over 100, 100 represents the whole thing 40 is the part so it's basically part over whole. 40% is your answer. I'm sorry if my explanation made no sense

if a sample size 40 is drawn from the population that has mean 276 and a variance of 81, what is the probability that the mean of the sample will be less than 273?
Answers
Answer:
The probability is 0.017429
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)/SD/√n
In this case;
x = 273
mean = 276
SD = √(variance) = √81 = 9
n = 40
Substituting these values into the z-score formula, we have that;
z = (273-276)/9/√40
z = -2.11
So we proceed to get the probability
the probability in this case is;
P( z < -2.11)
We can use the normal distribution table for this
Our answer will be
P( z < -2.11) = 0.017429

E. 100,000 - 2 with the power of 5
Answers
Answer:
The answer is C and E.
Step-by-step explanation:
I just took the assignment and it is C and E.
The expression that represents the population after 5 decades is
100,000 x [tex]2^5[/tex] or 100,000 x 2 x 2 x 2 x 2 x 2.
Options C and E is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 8 is an equation.
We have,
The population of the city = 100,000
Population doubles every decade.
This means,
Population after 1 decade.
= 100,000 x 2
= 200,000
Population after 2 decades.
= 200,000 x 2 x 2
= 800,000
We can write an expression for the population after x decade.
= 100,000 x [tex]2^x[/tex]
The population after 5 decades.
= 100,000 x [tex]2^5[/tex]
= 100,000 x 2 x 2 x 2 x 2 x 2
= 100,000 x 32
= 3200,000
Thus,
The expression is 100,000 x [tex]2^5[/tex] or 100,000 x 2 x 2 x 2 x 2 x 2.

2. x ≈ 17.74
3. x ≈ 16.64
Step-by-step explanation:
The tangent function relates an angle to the opposite and adjacent sides of a right triangle:
Tan = Opposite/Adjacent
Here, we're looking for the measure of the side opposite the angle, so we can rearrange this relation to ...
Opposite = Adjacent×Tan
__
2. x = 32×tan(29°) ≈ 17.74

[tex]a=\sqrt{33}[/tex]
Step-by-step explanation:
When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know b and c we can plug that in to find out what a could be but we won't actually solve it.
[tex]a^2+b^2=c^2\\a^2+4^2=7^2\\a^2+16=49\\a^2=33\\\sqrt{a^2}=\sqrt{33}\\a=\sqrt{33}[/tex]
So a would equal whatever the square root of 33 is.
A friend has a 83% average before the final exam for a course. That score includes everything but the final, which counts for 25% of the course grade. What is the best course grade your friend can earn? % What is the minimum score would your friend would need on the final to earn a 75% for the course? %
Answers
Answer:
[tex]\mathrm{Best\:course\:grade\:possible:\:}87.25\%,\\\mathrm{Minimum\:score\:on\:final\:to\:earn\:at\:least\:a\:75\%\:for\:the\:course:\:}51\%[/tex]
Step-by-step explanation:
Assuming the maximum score for the final is [tex]100\%[/tex], we can multiply each score by its respective course weight and add them together to give a final score. If your friend did receive this maximum score of [tex]100\%[/tex], their overall grade for the course would be:
[tex]83(1-0.25)+100(0.25)=\fbox{$87.25\%$}[/tex].
To find the minimum score they need to earn a 75% for the course, we set up the following equation:
[tex]83(1-0.25)+x(0.25)=75[/tex], where [tex]x[/tex] is the minimum score she needs.
Solving, we get:
[tex]62.25+x(0.25)=75,\\x(0.25)=12.75,\\x=\fbox{$51\%$}[/tex].
