Step-by-step explanation:
The probability that it will rain on wednesday will be 0.75.
What is a expression? What is a mathematical equation? What is Probability?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. The formula to calculate the probability of occurrence of an event 'A' can be written as -
P(A) = n(A)/n(S)
where -
n(A) = Number of outcomes favorable to event A.
n(S) = Total number of outcomes.
We have a meteorologist who says that there is a 50% greater chance of rain than no rain on Wednesday.
Assume that the probability that it will rain on wednesday be [x]. Now, we can write -
P[R] = P[N.R.] + 1/2
P[R] + P[R] = P[N.R.] + P[R] + 1/2
2 P[R] = 1 + 1/2
2 P[R] = 1.5
P[R] = 1.5/2
P[R] = 0.75
Therefore, the probability that it will rain on wednesday will be 0.75.

Answer:
angle 4 = 56°
Step-by-step explanation:
Interior angles in the same side of the transversal are supplementary (their sum is 180°)
Angle 1 and 4 are interior angles on the same side of the transversal.
So, angle 1 + angle 4 = 180°
Angle 1 = 124° (given)
124 + angle 4 = 180°
angle 4 = 180° - 124° = 56°
Therefore, angle 4 = 56°

which inequality represents the solutions to the inequality −5r+18≤2−3r?
Answer:
2 step equation problems.
Step-by-step explanation:
So you need to replace -3 into that to add -18 on both sides and that gives you the negative number is -20 and then you add the -5r+-3r less than or equal to -20. Now, negative -5 +3 = -8 + -20 = -28. r=-28.
You are making a scale model of a sports field. The
actual field is a rectangle with a length of 315 ft and a
width of 300 ft. Your scale model is 15 in. wide. What is
its length in inches?
Answer:
15.75 inches
Step-by-step explanation:
You can use a ratio to find your answer by cross multiplying.
300 ft 315 ft
---------- = ----------
15 in x in
Cross multiplying would give you:
300x = 15 x 315
300x = 4725
x = 4725 / 300
x = 15.75 inches

Sandra drove 117 miles in an hour and 30 minutes to visit her son at college, without stopping. If the speed limit is 60 mph, explain why she should or should not get a speeding ticket. Make sure to include mathematical computations in your answer.
Answer:
She should get a speeding ticket. The speed limit is 60mph and her speed was 78 mph, 18 miles over the speed limit.
Step-by-step explanation:
She drove 117 miles in 90 minutes.
117/90 = 1.3 miles per minute
1.3 miles x 60 minutes = 78 mph
A number is multiplied by 3. Next, 6 is added to the product. Then, the sum is divided by 8. If the result is 6, what is the number?
Answer:
14
Step-by-step explanation:
14 x 3 = 42
42 + 6 = 48
48 ÷ 8 = 6
Therefore, the answer is 14.
Answer:
14
Step-by-step explanation:
let us call the number x for now
the number (x) is multiplied by 3 to give us
3x
then,
it is added to 6 to give
3x + 6
then, our sum is divided by 8:
(3x + 6) / 8
according to the question, the result is 6
therefore,
3x + 6 / 8 = 6
if we cross multiply,
3x + 6 = 8 ( 6 )
3x + 6 = 48
collecting like terms,
3x = 48 - 6
3x = 42
divide through by 3 to give
3x / 3 = 42 / 3
x = 14
therefore, x = 14
to reassure us of our answer,
since (3(x) + 6) / 8 = 6
and we know that x = 14,
therefore,
(3(14) + 6) / 8 = 6
(42 + 6) / 8 = 6
48 / 8 = 6
6 = 6
therefore, we are now sure that x = 14
hope this helps

Is it possible for a number to be a rational number that is not an integer but is a whole number?
Answer:
The rational numbers include all the integers, plus all fractions, or terminating decimals and repeating decimals. Every rational number can be written as a fraction a/b, where a and b are integers. If a number is a whole number, for instance, it must also be an integer and a rational.

The answer is 12 , -7
I just need the steps
Answer: -7, 12
Step-by-step explanation:
a+b = 5

The price of a dress was reduced from $40 to $30. By what percentage was the price of the dress reduced? STEP BY STEP
Answer:
The price was reduced by 25%
Step-by-step explanation:
Not sure how to go step by step on this, because it's kinda obvious once you think about it a bit. You need to find what percent of 40 that 10 equals (if that makes sense). So really it's just what percent of 40 equals 10? and since 10 is one fourth of forty, 1/4, then you convert that to percent: 25% (sorry if this made no sense, i'm not very good at explaining things)
The figures are similar. Find x ,
Answer:
8 cm
Step-by-step explanation:
Hello there! :)
We are given that these figures are similar.
It means that the sides are proportional. So
[tex]\frac{4}{6} =\frac{6}{x}[/tex]
Cross-multiply:
4x=36
Divide both sides by 4 to isolate x:
x=9 cm

Rewrite y - 3 = -9(x - 1) in standard form.
Answer:
9x + y = 12
Step-by-step explanation:
Hi there!
We are given the equation y - 3 = -9(x-1) and we want to write it in standard form
The equation is currently in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where [tex](x_1 , y_1)[/tex] is a point and m is the slope. Standard form is ax + by = c, where a, b, and c are free integer coefficients
We can first convert the equation from point-slope form into slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
We can distribute 9 to every term on the right side:
y - 3 = -9x + 9
Now add 3 to both sides
y = -9x + 12
Now the equation is in slope-intercept form (y=mx+b). To make it standard form, add 9x to both sides, to make the form ax + by = c .
9x + y = 12
Hope this helps!
