What's (7.3 x 10^-1) (.004) in standard notation
Answer:
.73(.004) or .00292
Step-by-step explanation:
First, you should look at the equation: (7.3x10^-1). This means you would have to move the decimal to the left one time. So, the equation would be .73(.004).
If you wanted to find the answer to this equation, you would get .00292.
Standard notation: (.73)(.004).
Answer:
2.92 x 10⁻³Step-by-step explanation:
(7.3 x 10⁻¹) (0.004) = (7.3 x 10⁻¹)(4 x 10⁻³) =(7.3*4) x 10⁻¹⁻³ =29.2 x 10⁻⁴ = 2.92 x 10⁻³In a class of 29 students, 20 have a brother and 8 have a sister. There are 3 students who do not have any siblings. What is the probability that a student chosen randomly from the class is an only child?
Answer: 1/4 = 0.25 = 25%
Step-by-step explanation:
Let x be the number of students having both brother and sister.
Brother only is 9-x
Sister only is 16-x
Brother only + sister only + both + neither = 28
(9-x) + (16-x) + x + 7 = 28
32 - x = 28
x = 4
The probability per the diagram is 4/16 = 1/4
Per definition of conditional probability:
prob( brother | sister) = prob ( brother AND sister) / prob ( sister)
= 4/16 = 1/4
1/4 = 0.25 = 25%

A right triangle undergoes a sequence of transformations to generate a new
triangle. Which of the following sequences of transformations would result in
the two triangles being similar but not congruent?
Answer:
Option a.
Step-by-step explanation:
Two figures are similar if they have the same shape, but maybe different sizes, so if we have a triangle, and we dilate/contract it with a scale factor K, the original triangle and the dilated/contracted one will be similar.
Two figures are congruent if they have the same shape and size. For example, transformations that do not change the size will make congruent figures, those transformations are reflections, rotations and translations.
Now we need to find a sequence of transformations that would result in the two triangles being similar but no congruent, then we need to find the sequence of transformations that has a dilation/contraction in it.
The only sequence that has a dilation is the first one:
a) Rotation 90° centered about the origin, followed by a dilation of scale factor 3 centered about the origin.
Then option a is the correct one.

A class collects data on the number of movie tickets purchased and the total cost of those tickets. The class plots the data on a scatter plot. Which statement BEST interprets their results?
A.
There is likely to be correlation between the number of movie tickets purchased and the total cost of those tickets but not causation.
B.
There is likely to be both correlation and causation between the number of movie tickets purchased and the total cost of those tickets.
C.
There is likely to be neither correlation nor causation between the number of movie tickets purchased and the total cost of those tickets.
D.
There is likely to be causation between the number of movie tickets purchased and the total cost of those tickets but not correlation.
Answer:
Step-by-step explanation:
There is likely to be correlation between the number of movie tickets purchased and the total cost of those tickets but not causation.
'There is likely to be correlation between the number of movie tickets purchased and the total cost of those tickets but not causation.' This statement best interprets their results.
What is correlation?It is a relationship between two variables or events. However, one variable doesn't actually cause the other.
What is causation?Causation can be applied on two events or variables where variable 2 causes the variable 1.
The class collects data on the number of purchased and the total cost of those tickets.
Let, for a particular time period, this observation is recorded.
Hence, the number of movie tickets purchased and the total cost of those tickets this must be correlation. It can't be causation. Option: A is right.

Is 301 in the sequence below?
-9, -5,-1,3,7,...
Answer:
no
Step-by-step explanation:
Establish the nth term formula
There is a common difference d between consecutive terms, that is
d = - 5 - (- 9) = - 1 - (- 5) = 3 - (- 1) = 7 - 3 = 4
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 9 and d = 4 , then
[tex]a_{n}[/tex] = - 9 + 4(n - 1) = - 9 + 4n - 4 = 4n - 13
Equate 4n - 13 to 301
4n - 13 = 301 ( add 13 to both sides )
4n = 314 ( divide both sides by 4 )
n = 78.5
Since n is not an integer then 301 is not in the sequence
301 doesn't belong to the sequence -9, -5,-1,3,7,...
What is A.P sequence?An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
The arithmetic sequence is given by a, a + d, a + 2d, a + 3d, … .
Hence, the formula to find the nth term is:
[tex]a_{n}[/tex] = a + (n – 1) × d.
where,
a = first term
d = common difference
n = number of terms
[tex]a_{n}[/tex] = nth term
According to the question
Sequence : -9, -5,-1,3,7,...
First term (a)= -9
common difference (d)= -5 - (-9)
= 4
[tex]a_{n}[/tex] = 301
using the formula of nth term
[tex]a_{n}[/tex] = a + (n-1)d
Substituting the value
301 = -9 + (n-1) 4
310 = (n-1) 4
77.5 = (n-1)
n = 78.5
as n always to be the whole number .
Hence, 301 doesn't belong to the sequence -9, -5,-1,3,7,...

Based on the table, how much more money would a person with a bachelor's degree earn than a person with an associate's degree over a 30 year career?
A) $16,000
B) $480,000
C) $1,095,000
D) $1,575,000
Answer:
B) $480,000
Step-by-step explanation:
Annual salary of a person with associate's degree
= $36,500
Over a 30 year career the person would earn;
= 30 × 36500
= $10,95,000
Now, annual salary of a person with bachelor's degree = $52,500
Over a course of 30 years he would earn;
= 30 × 52500
= $15,75,000
Difference = $15,75,000 - $10,95,000 = $480,000
So the person with bachelor's degree would earn $480,000 more than a person with associate's degree.

The resale value of a bike decreases by 14% per year. A new bike is valued at $350. Approximate the resale value after 4 years to the nearest dollar.
Answer: $191.45
Step-by-step explanation:
This question requires the price of a bike in future so you can use the future value formula to calculate it:
Future value = Amount * (1 + rate)^ no. of periods
= 350 * (1 - 14%)⁴
= 350 * 0.54700816
= $191.45
The rate is subtracted from 1 instead of being added to represent that the value is decreasing not increasing.

A triangle has three angles that measure 30 degrees, 70 degrees What is the value of x?
Answer:
x = 80
Step-by-step explanation:
Sum of all the angles of triangle = 180
30 + 70 + x = 180
100 + x = 180 {Subtract 100 from both sides}
x = 180 - 100
x = 80°
Write the equation of the line that passes through the points (−3, 5) and (2, -10) in slope-intercept form.
Answer:
[tex]y=-3x-4[/tex]
Step-by-step explanation:
Hi there!
Slope intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
1) Determine the slope (m)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (−3, 5) and (2, -10)
[tex]m=\frac{-10-5}{2-(-3)}\\m=\frac{-10-5}{2+3}\\m=\frac{-15}{5}\\m=-3[/tex]
Therefore, the slope is -3. Plug -3 into [tex]y=mx+b[/tex] as m:
[tex]y=-3x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=-3x+b[/tex]
Plug one of the given points, (−3, 5) or (2, -10) into the equation and isolate b
[tex]5=-3(-3)+b\\5=9+b[/tex]
Subtract 9 from both sides
[tex]5-9=9+b-9\\-4=b[/tex]
Therefore, the y-intercept is -4. Plug -4 into [tex]y=-3x+b[/tex] as b:
[tex]y=-3x-4[/tex]

∠ A ≈ 77.8°
Step-by-step explanation:
Using the Sine rule in Δ ABC
[tex]\frac{BC}{sinA}[/tex] = [tex]\frac{AB}{sinC}[/tex]
[tex]\frac{37}{sinA}[/tex] = [tex]\frac{29}{sin50}[/tex] ( cross- multiply )
29 × sinA = 37 × sin50° ( divide both sides by 29 )
sinA = [tex]\frac{37sin50}{29}[/tex] , then
A = [tex]sin^{-1}[/tex] ( [tex]\frac{37sin50}{29}[/tex] ) ≈ 77.8° ( to 1 dec. place )
