Alona is using a quantitative approach to her studies.
What is Quantitative research?The goal of quantitative research is to quantify the data collection and processing process.
It is based on a deductive method that emphasizes the validation of the hypothesis and is influenced by positivist and empiricist theories.
This research technique, which is related to the natural, applied, formal, and social sciences, encourages the unbiased empirical exploration of observable phenomena to test and comprehend correlations.
This is accomplished using a variety of quantification techniques and procedures, demonstrating the wide application of this approach as a research strategy across numerous academic fields.
So, in the given situation, Alona is using the quantitative research method.
Therefore, Alona is using a quantitative approach to her studies.

A. 5^3 + x
B. 125•5^3
C. (5 • x)^3
D. 25^3x
E. 53^3x
F. 53^3-x
Hi there, I'll help you out :)
The expression that is equivalent to 5^3 • 5^x is A. If you solve the expression given in the question, you get 5^3 + x, which is exactly the same as the first choice.
- B gives you 15625
- C gives you 125x^3
- D gives you 15625^x
- E gives you 148,877^x
- F can't really be solved

The expressions which are equivalent to the one given below are 5³⁺ˣ and 125 (5ˣ).
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is,
5³ . 5ˣ
We have the product rule of exponents that,
xᵃ . xᵇ = xᵃ⁺ᵇ
Using the same here,
5³ . 5ˣ = 5³⁺ˣ ------(1)
Now the value of 5³ = 5 × 5 × 5 = 125
So, 5³ . 5ˣ = 125 (5ˣ) --------(2)
Hence the equivalent expressions are 5³⁺ˣ and 125 (5ˣ).

Solve for q: 2q- 12 = -40
Answer:
q = -14
Step-by-step explanation:
2q - 12 = -40
Add 12 to both sides
2q - 12 + 12 = - 40 + 12
2q = - 28
Divide both sides by 2
2q/2 = -28/2
q = - 14

Suppose you receive a postcard from a good friend with a picture of the Golden Gate Bridge in San Francisco. The postcard is 3.5 inches high and 5.5 inches wide. The fine print on the postcard states that the scale of the picture is 1:19,600. Based on the scale, what's the actual length of the Golden Gate Bridge? O
A. 10,760 feet O B. 21, 552 feet O C. 8,980 feet O D. 8,167 feet
Actual length of the Bridge = 8983.33 feet.
The scale is 1 unit = 19,600.
Height of the postcard is 3.5 inches.
So, original height of the bridge = 3.5 × 19,600 = 68,600 inches
= 5716.67 feet
Width of the postcard is 5.5 inches.
So, original width of the bridge = 5.5 × 19,600 = 107,800 inches
= 8983.33 feet
hope it helps
The correct option is (c) 8980 feet.
What is length ?The measurement or size of something from end to end is referred to as its length. To put it another way, it is the greater of the higher two or three dimensions of a geometric shape or object. For example - A rectangle, for instance, has length and breadth as its dimensions. Two hours is an example of length for a movie. 12 inches is an illustration of length.Given,length of the Bridge = 8983.33 feet.
The scale is 1 unit = 19,600.
Height of the postcard is = 3.5 inches.
So,
Original height of the bridge = 3.5 × 19,600 = 68,600 inches
= 5716.67 feet
Width of the postcard is 5.5 inches.
So, original width of the bridge = 5.5 × 19,600 = 107,800 inches
= 8983.33 feet
Therefore, the original width of the bridge is 8983.33 feet .

Find an equation in slope-intercept form of the line that has slope 2 and passes through point A(-3. - 1)
Answer:
Step-by-step explanation:
m = 2 ; x1 = -3 ; y1 = -1
Slope- point form: y - y1 = m(x -x1)
y - [-1] = 2(x - [-3])
y + 1 = 2(x + 3)
y + 1 = 2x + 3*2
y + 1 =2x + 6
y = 2x + 6 - 1
y = 2x + 5 This is slope intercept form : y = mx + b

David rode his bike a total of 214 miles from his house to the store. First he rode 34 mile from his house to his school. Then he rode 14 mile from his school to the library. Finally he rode from the library to the store. How many miles did David ride between the library and the store?
Answer:
166 miles
Step-by-step explanation:
Add the 34 miles he rode from home to school and the 14 miles he rode from school to the library.
34 + 14 = 48.
Subtract 48 from 214 to get 166
214 - 48 = 166
David rode 166 miles between the library and the store.

An experiment reported in Popular Science compared fuel economies for two types of similarly equipped diesel mini-trucks. Let us suppose that 12 Volkswagen and 10 Toyota trucks were tested in 90- kilometer-per-hour steady-paced trials. If the 12 Volkswagen trucks averaged 16 kilometers per liter with a standard deviation of 1.0 kilometer per liter and the 10 Toyota trucks averaged 11 kilometers per liter with a standard deviation of 0.8 kilometer per liter, construct a 90% confidence interval for the difference between the average kilometers per liter for these two mini-trucks. Assume that the distances per liter for the truck models are approximately normally distributed with equal variances.
Answer:
CI= [4.324 , 5.6758]
Step-by-step explanation:
The 90 % confidence interval for the normal distribution is given by
(x`1- x2` ) ± t ∝/2 (υ) .Sp √1/n1 + 1/n2
where Sp = √[n1-1 (s1)² + n2-1 (s2)²]/n1+n2-2
and n1= 12 n2=10
x1`= 16 km x`2 = 11km
s1= 1km s2= 0.8km
and degrees of freedom υ= n1+n2-2= 20
Here ∝/2 = 0.05
From the table we get the value of t∝/2 (υ) to be 1.725
Putting the values
Sp = √[n1-1 (s1)² + n2-1 (s2)²]/n1+n2-2
Sp= √11(1) + 9(0.8)²/20
Sp= √0.838=0.915
CI = (x`1- x2` ) ± t ∝/2 (υ) .Sp √1/n1 + 1/n2
CI = (16-11)± 1.725 * 0.915√1/12+ 1/10
CI = (5) ± 0.675819
CI=[ 4.324 , 5.6758]
