solve for b: 8ab=c thanks (:
Answer:
You must move the a and 8 to the other side of the equation. Just divide both sides by 8a.
B = c \ 8a.. c over 8a
The value for b is c/8a.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
8ab=c
Now, solving for b
8ab= c
ab= c/8
or, b = c/8a
Hence, the value for b is c/8a.

Angles RLN and MLK would be vertical angles.
Vertical angles are formed when their sides share the same lines. RL shares the same line with LM and NL shares the same line with LK (see the attached diagram), so that means both angles form a vertical pair.

g Suppose 40% of the students in a university are baseball players. If a sample of 781 students is selected, what is the probability that the sample proportion of baseball players will be greater than 43%
Answer: 0.1271
Step-by-step explanation:
Let p= probability of the students in a university are baseball players.
Given: p= 0.40 , sample size : n= 781
The probability that the sample proportion of baseball players will be greater than 43% will be:
[tex]P(p>0.43)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.43-0.41}{\sqrt{\dfrac{0.41(1-0.41)}{781}}}\\\\=P(Z>1.14)\ \ \ [Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]\\\\=1-P(Z<1.14)\\\\=1- 0.8729=0.1271[/tex]
Hence, the probability that the sample proportion of baseball players will be greater than 43% = 0.1271

Which graph shows an odd function?
Answer: The correct answer is c
Step-by-step explanation:
Graph C depicts an odd function.
We have the four graphs as shown in the figure.
We have to determine which graph depicts an odd function.
What is an Odd function?Assume a function f(x), if : [tex]f(-x) = -f(x)[/tex] i.e., absolute value remains the same if the sign of the independent variable is reversed.
Remember - A function is called even if its graph is symmetrical about the y - axis, odd if its graph is symmetrical about the origin.
It can be seen that - Graph A, Graph B, Graph D are not symmetrical about the origin. Only Graph C - Sine wave is symmetrical about Origin.
Hence, Option C is the graph that depicts the odd function.

The largo middle school track team needs new uniforms. The students plan to sell push you tigers (the school mascot) for $5. The students find three companies online that sell stuffed mascots.
A.which company has the lowest cost per tiger?
B. If they use the company, how much profit will the students make for each tiger sold?
P.s-I REALLY NEED HELP!!!! This question is worth 60 points
Answer:
Company C has the lowes cost per tiger at $2.74. (Divide the prices by the number of stuffed animals, in this case, $41.10/15)
$2.26 would be their profit.
Step-by-step explanation:
To find how much money they have to pay for each stuffed animal, you have to divide the prices by the number that would be sold. For example, for Company C, it would be $41.10 divided by 15. When you do that with all the companies, you'll find the Company C is the cheapest.
You find their profit by subtracting $2.74 from $5. They sell it for $5, but they did have to use $2.74 to buy the stuffed animals. $5 - $2.74 = $2.26
Hope this helps! ^-^
Company C has the lowest cost per tiger.
Students will make a profit of $2.26 for each tiger sold.
What is division?The division is the process of dividing a number by a given number.
Note that company A offers 12 tigers for $33.24, therefore, divide 33.24 by 12 to get the cost of one tiger,
Cost of one tiger in company A = $33.24/12 = $2.77
Similarly,
The cost of one tiger in Company B = $44.80/16 = $2.8
The cost of one tiger in Company C = $41.10/15 = $2.74
Clearly, company C has the lowest cost per tiger.
Now, students will buy tigers from Company C for $2.74 per tiger and sell them for $5, therefore, the profit from selling one tiger will be 5-2.74=2.26.

1. If, based on a sample size of 850, a political candidate finds that 458 people would vote for him in a two-person race, what is the 95% confidence interval for his expected proportion of the vote
Answer:
The 95% confidence interval is
[tex]0.5055< p <0.5725[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 850
The number of can of people that will vote in a two people race is k = 458
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{k}{n}[/tex]
=> [tex]\^ p = \frac{458}{850}[/tex]
=> [tex]\^ p = 0.539[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p(1- \^ p)}{n} } [/tex]
=> [tex]E = 1.96 * \sqrt{\frac{0.539(1- 0.539)}{850} } [/tex]
=> [tex] E = 0.0335[/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\r p -E < p < \r p +E[/tex]
=> [tex] 0.539 - 0.0335< p < 0.539 + 0.0335[/tex]
=> [tex]0.5055< p <0.5725[/tex]

Thunder is the sound caused by lightning. You hear thunder 5 seconds after a lightning strike. The speed of sound is about 1225 kilometers per hour. About how many miles away was the lightning?
Answer:
it is 1.05
Step-by-step explanation:
The lightning was 1.7 kilometer away.
What is speed?In unit time, the distance covered by any object is called speed.
In mathematical term, Speed is express as S=D/T,
where S=speed, D=distance, T= time.
Given that,
The speed of sound = 1225 kilometers per hour
The speed of sound = 340.277 meter/second
Also, the time after thunder heard = 5 seconds
To find distance, use formula distance = speed × time,
Distance = 340.277 × 5
= 1701.3 meter
= 1.7 kilometer
The lightning was 1.7 kilometer away.
