questions on a math exam.
What percent of questions did
she answer correctly?
I NEED TO SHOW MY WORK step by step explanation plz
Answer:
80%
Step-by-step explanation:
To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.
part = 48
whole = 60
percent = part/whole * 100%
percent = 48/60 * 100%
percent = 80%
Answer: 80%
Amanda answered 80 % of question correctly.
Given that, Amanda correctly answered 48 of the 60 questions on a math exam.
Percent of question, she answer correctly,
[tex]=\frac{48}{60}*100=\frac{8}{10}*100 =80 [/tex]

SAS (side angle side)
Step-by-step explanation:
This rule states that if 2 sides are equal and the angle between the sides are also equal, then the 2 triangles must be congruent.
Therefore, the answer must be SAS (side angle side).

Question 1: A researcher wants to know about the average salary of all General Motors workers. The data can only be collected as whole US dollars. This data can be considered: * qualitative nominal qualitative ordinal quantitative discrete quantitative continuous Question 2: A researcher pla
Answer:
Quantitative Discrete
Step-by-step explanation:
The data about the average salary of all general motor workers cooled ONLY as WHOLE U. S DOLLARS
Firstly, data involving worker's salary are best expressed in figure, hence making such data numerical in nature. Numerical variables are quantitative data as it allows for numerical computation and analysis such as addition, subtraction, mean of the data values and so on.
Secondly, since these data has been strictly restricted to be expressed in whole numbers, this makes the range of the data collected finite and hence countable. This properties ensure that the quantitative data (average salary) is discrete in nature.

find the measures of angles 1, 2, and 3
x = 33°
Then :-
m∠1 = 33° ( angle x and angle 1 are corresponding angles on a transversal )
Which means :-m∠1 + m∠2 = 90° ( angle 1 and angle 2 are complementary angles )
33 + ∠2 = 90
∠2 = 90 - 33
m∠2 = 57°
Then :-m∠1 + m∠3 = 180° ( angle 1 and angle 3 are a linear pair )
33 + ∠3 = 180°
∠3 = 180 - 32
m∠3 = 147°
Therefore , m∠1 = 33°m∠2 = 57° m∠3 = 147°What is the solution to 2x-8 <12?

What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is 2x-8<12
Two times of x minus eight less than twelve
x is the variable
We have to find the solution of the inequality

Simplify and write answer in terms of i as appropriate. *. i^25
Answer:
i
Step-by-step explanation:
Given the complex value i^25, we are to write in terms of i. In complex number:
i² = -1
i^25 =( i²)¹² × i
= (-1)¹² × i
Note that -1 to a negative number will give a positive number hence (-1)¹² = 1
(-1)¹² × i = 1×i
= i
Hence i^25 = i

The weight of mr nazeer is 7 times that of his son. What's the ratio of their weights?
Answer:
7:1Step-by-step explanation:
Let the weight of mr nazeer be x
Let the weight of his son be y
If the weight of mr nazeer is 7 times that of his son, then x = 7y
To get the ratio of their weight:
Ratio = weight of father/weight of son
Ratio = 7y/y
Ratio = 7/1
Ratio = 7:1
Hence the ratio of their weights is 7:1
Five different companies (G, J, S, O, U) compete each year to be the sole supplier of relays to a major automobile manufacturer. Supplier G J S O U probability .15 .04 .01 .55 .25 Given that suppliers O and U are both ultimately not chosen, what is the probability that supplier S will be chosen
Answer:
The probability is [tex]P(S | (O ,U)' ) = 0.05[/tex]
Step-by-step explanation:
From the question we are told that
The probability of each company to be chosen is
Supplier G J S O U
Probability 0.15 0.04 0.01 0.55 0.25
Generally the probability that company G , J , S are chosen is
[tex]P(G , J , S ) = 0.15 + 0.04 + 0.01[/tex]
=> [tex]P(G , J , S ) = 0.20[/tex]
Generally the probability that company O, U are chosen is
[tex]P(O, U ) = 0.55+ 0.25[/tex]
=> [tex]P(O, U ) = 0.80[/tex]
Generally the probability that supplier S will be chosen given that suppliers O and U are both ultimately not chosen is mathematically represented as
[tex]P(S | (O ,U)' ) = \frac{ P(S \ n \ (O , U)' )}{ P((O, U)')}[/tex]
[tex]P((O, U)' = 1 - P(O , U)[/tex]
[tex]P((O, U)' = 1 - 0.8[/tex]
[tex]P((O, U)' =0.2[/tex]
And
[tex]P(S \ n \ (O , U)' ) = P(S) = 0.01[/tex]
=> [tex]P(S | (O ,U)' ) = \frac{ 0.01 }{ 0.2}[/tex]
=> [tex]P(S | (O ,U)' ) = 0.05[/tex]
Las bacterias son seres vivos minúsculos que se reproducen dividiéndose por la mitad cada
cierto tiempo. Suponemos una bacteria que se divide cada minuto. En ese caso, después de
dos minutos tendríamos cuatro bacterias, a los tres minutos ocho bacterias y así
sucesivamente. Con ayuda de la escena contesta en tu cuaderno a las siguientes preguntas:
a.- ¿Cuántas bacterias habrá a las dos horas?
b.- Averigua cuánto tiempo hará falta para que haya 33.554. 432 bacterias.
Answer:
a) Entonces, habrá una población de [tex]1.329\times 10^{36}[/tex] bacterias a las dos horas.
b) La población de bacterias será de 33554432 en 25 minutos.
Step-by-step explanation:
a) De acuerdo con el enunciado, podemos apreciar una progresión geométrica, la cual está definida como:
[tex]n = n_{o}\cdot r^{t}[/tex] (Eq. 1)
Donde:
[tex]n_{o}[/tex] - Población inicial de bacterias, adimensional.
[tex]n[/tex] - Población actual de bacterias, adimensional.
[tex]r[/tex] - Tasa de reproducción de la población, adimensional.
[tex]t[/tex] - Tiempo, medido en minutos.
Si sabemos que [tex]n_{o} = 1[/tex], [tex]r = 2[/tex] and [tex]t = 120\,min[/tex], entonces la población actual de las bacterias:
[tex]n = 1\cdot 2^{120\,min}[/tex]
[tex]n = 1.329\times 10^{36}\,bacterias[/tex]
Entonces, habrá una población de [tex]1.329\times 10^{36}[/tex] bacterias a las dos horas.
b) Si empleamos (Eq. 1) y asumimos que [tex]n_{o} = 1[/tex], [tex]r = 2[/tex] and [tex]n = 33554432[/tex], entonces despejamos [tex]t[/tex] de la fórmula resultante:
[tex]1\cdot 2^{t} = 33554432[/tex]
[tex]2^{t} = 33554432[/tex]
[tex]\log_{2} 2^{t} = \log_{2} 33554432[/tex]
[tex]t = \log_{2} 33554432[/tex]
[tex]t = 25\,min[/tex]
La población de bacterias será de 33554432 en 25 minutos.

[tex](h + k)(x) = 2x - 1[/tex]

Fatima has a student loan the loan amount is 15,000 for 10 years her interest rate is 8.25% how much will Fatima pay in interest
Answer:
8212.67
Step-by-step explanation:
From the data given in the question;
Amount = 15000
Principal = ?
rate = 8.25%
time = 10 years
From;
A =P(1 + r)^n
15000 = P(1 + 0.0825)^10
P= 15000/2.21
P= 6787.33
but
Interest = Amount - Principal
Interest = 15000 - 6787.33
interest = 8212.67
A cash register contains q quarters. Write an algebraic expression that represents the total amount of money (in dollars).
Answer:
0.25q
Step-by-step explanation:
A cash register is a machine used in small business that sums, display and records the total amount made by each sale. A cash register also has a drawer which is used to store money.
A quarter is a coin in the United States which is 25 cents.
Converting 25 cents to dollars:
100 cents = $1
25 cents = 25 cents × $1 / 100 cent = $0.25
The total amount of money registered = number of quarters × $0.25
The total amount of money registered = q × $0.25 = 0.25q

The heights of adult females are normally distributed. If you were to construct a histogram of 40 randomly selected women, what shape would the histogram of those heights have and what pattern would you expect in a normal quantile plot of these data?
a. The histogram would by approximately bell-shaped, and the normal quantile plot would have data points that would be bell-shaped.
b. The histogram would by non-symmetric, and the normal quantile plot would have data points that would be non- linear.
c. The histogram would by approximately bell-shaped, and the normal quantile plot would have data points that would be non-linear.
d. The histogram would be approximately bell-shaped, and the normal quantile plot would have data points have follow a straight-line pattern.
Answer:
d. The histogram would be approximately bell-shaped, and the normal quantile plot would have data points have follow a straight-line pattern.
Step-by-step explanation:
Since the variable is normally distributed, the histogram of women's height should be approximately bell shaped (if the data was obtained form a random sample).
Again, the variable is normally distributed, therefore, the quantile plot should follow a straight line pattern (a diagonal line to be more precise).
