If Mr. Argo went 20 miles on 2.5 gallons of gas, and he wants to know how far he can go on 9 gallons of gas. Which proportion would be helpful to solve the problem?
A.20/9 = 2.5/x
B. 9/2 = 20/x
C. 20/2.5 = x/9
D.9/20 = x/2
Answer:
3/4 = 12/16, y = 2, w = 2.5, 20/2.5 = x/9
Step-by-step explanation:
The first question is asking which is proportional.
B. 3/4 = 12/16
We know this is proportional because 4 can be multiplied by 4 to get 16, and the same can be applied to 3 to get 12.
The second question is asking for the missing value of y.
3/12 = y/8
y = 2
We can solve this by looking at the 12 and the 8.
8 is 2/3 of 12.
2/3 of 3 is 2
The third question is asking for the missing value of w.
5/w = 8/4
w = 2.5
We can solve this by looking at the 8/4.
8/4 is the same as 2/1.
Using this, we can conclude that w = 2.5
The fourth question is asking for the correct proportion.
If Mr. Argo can go 20 miles on 2.5 gallons of gas:
20/2.5
And he wants to know how many miles he can go with 9 gallons:
x/9
We can use the equation: C. 20/2.5 = x/9

In statistics, Probability defines the possible way of occurring a particular event.
Given,
A flipped coin can land in one of two states: heads or tails.
Here we need to find the probability while flipping four coins then how many of these coins land in the heads state.
In order to calculate the probability of these event, we have to know the values of the sample space and the possible number of events,
Here the value of sample space is written as,
S = {HHHH, TTTT, HHHT, HHTH, HTHH, THHH, HHTT, HTTH, HTHT, THHT, THTH, TTHH, HTTT, THTT, TTHT, TTTH}
So, the value of n(S) = 16
The possible number of way to obtain the head state is,
E = {HHHH, HHHT, HHTH, HTHH, THHH, HHTT, HTTH, HTHT, THHT, THTH, TTHH, HTTT, THTT, TTHT, TTTH}

Potential is described by probability. This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability has been applied into mathematics to predict the likelihood of different events.
Probability basically refers to the degree to which something is likely to occur. With the help of this fundamental theory of probability, which is also used to describe the probability distribution, you will discover the possible results for a random experiment. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.

if olive construction company gets the job, what is the probability that base construction company did not bid?
If Olive Construction Company won the job, there is a 0.4615 (or 46.15%) probability that Base Construction Company would not have submitted a proposal.
What is probability?Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or of a proposition being true.
The probability of an event is a number between 0 and 1, with 0 approximately denoting impossibility and 1 denoting certainty.
So, the probability that the base construction company did not bid:
[tex]\begin{aligned}& P(A \mid B)=\frac{P(B \mid A) P(A)}{P(B \mid A) P(A)+P\left(B \mid A^{\prime}\right) P\left(A^{\prime}\right)} \\& P\left(B^{\prime} \mid O\right)=\frac{P\left(O \mid B^{\prime}\right) P\left(B^{\prime}\right)}{P\left(O \mid B^{\prime}\right) P\left(B^{\prime}\right)+P(O \mid B) P(B)} \\& P\left(B^{\prime} \mid O\right)=\frac{(0.5)(0.3)}{(0.5)(0.3)+(0.25)(0.7)} \\& P\left(B^{\prime} \mid O\right)=\frac{0.15}{0.15+0.175} \\& P\left(B^{\prime} \mid O\right)=0.4615\end{aligned}[/tex]
Therefore, if Olive Construction Company won the job, there is a 0.4615 (or 46.15%) probability that Base Construction Company would not have submitted a proposal.

The measured height of the tree is found as 3.2 yards.
Explain the term trigonometric relation?Trigonometric ratios are based on the measurement of the ratio of sides of a right-angled triangle and contain the values of all trigonometric functions. These trigonometric ratios of a given acute angle are the ratios of the sides of such a right-angled triangle in respect to that angle.Let 'h' be the height of the three.
Let distance between student A and tree = x.
Using trigonometric relation;
tan 57 = h/x
x = h/tan 57 ......eq 1
tan 46 = h/(x + 1)
x + 1 = h/tan 46 ......eq 2
Equation eq 1 and eq 2.
h/tan 57 + 1 = h / tan 46
h / tan 46 - h / tan 57 = 1
Further solving,
h(tan 57 - tan 46) = tan 46.tan 57
h = tan 46 tan 57 / (tan 57 - tan 46)
h = 3.2 yards
Thus, the measured height of the tree is found as 3.2 yards.
