Answer:
Gasoline 7%
Step-by-step explanation:
2500 * 0,07 = 175
Number * 0, percent = answer
Gasoline is the part of Shaquira's budget which is $175.
What is Percentage?In mathematics, a value or ratio that can be expressed as a fraction of 100 is known as a percentage. To find the % of a number, divide it by its value, then multiply the result by 100. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.
As per the given data:
Shaquira's monthly income = $2,500
Monthly Budget Utilities = 18% of income
Entertainment = 9% of income
Rent = 51% of income
Gasoline = 7% of income
Food = 15% of income
To find which part is $175 let's calculate all parts:
Monthly Budget Utilities = (18/100) × 2,500 = $450
Entertainment = 9% × 2,500 = $225
Rent = 51% × 2,500 = $1275
Gasoline = 7% × 2,500 = $175
Food = 15% × 2,500 = $375
Hence, gasoline is the part of Shaquira's budget which is $175.

This lesson asked you to investigate what it means for data to fall within 1, 2, and 3 standard deviations from the mean in a variety of normal distribution curves. Imagine that you hold a position on your city council and are in charge of creating new programs to benefit members of your community. In some cases, you must also decide which parts of the population are eligible for enrollment in a given program. How might the concept of standard deviations from the mean be interpreted in your decisions? For example, is it fair to make most programs only available to populations within 1 standard deviation from the mean? Can you imagine cases where you might want to create new programs for people who fall toward the extreme ends of the distribution? Give your opinion as well as some examples.
Answer:
The data in statistics is generally supposed to deviate or vary from the mean. Standard deviations of 1, 2, and 3 are commonly used to calculate variability according to the empirical norm. In a normal distribution, we estimate 68 percent, 95 percent, and 98 percent of the data to be within 1, 2, and 3 standard deviations of the mean, respectively. This implies that the given percentage of data will lie within an interval of less than or greater than the standard deviation. If the values within a given standard deviation from the mean are standardized, the z value will always be equal to or less than the given standard deviation.
We should look at a program that aims to help people get out of poverty by using the standard deviation principle. The aim of the program is to provide free seeds to poor people who have been suffering from low yields due to the use of local seeds. If we use the definition of one standard deviation of the mean, or 2 and 3, we will favor the majority of people, but we will leave the poorest people in society behind.
Ms. McClain conducted an experiment
with a 6-sided number cube. The table
shows the number of times each number
landed:
(I'll give brainlist)
Answer: 1
Step-by-step explanation:
Experimental probability is the actual result you get from an experement.
Theoretical probability is the change that you will get that result.
(for example: flipping a coin, the Theoretical probability is 50/50 but after testing the Experimental probability might be 47/53)
therefore,
1/6 is the Theoretical probability because you are using a six-sided number cube.
for the Theoretical probability and the Experimental probability to be the same, the fraction of the roll must equal 1/6.
1/6 equals 8/48.
therefore, since the numbers 1 and 6 were both rolled 8 times out of 48 they are consistant with the Theoretical probability of 1/6.
6 is not one of the answer choices listed so 1 must be your answer.

[tex] R = \frac {3ST}{2S + T} [/tex]
Step-by-step explanation:
Given the equation;
[tex] \frac {3}{R} - \frac {1}{S} = \frac {2}{T} [/tex]
Rearranging the equation, we have;
[tex] \frac {3}{R} = \frac {2}{T} + \frac {1}{S} [/tex]
Lowest common multiple (LCM) of S and T is ST.
[tex] \frac {3}{R} = \frac {2S + T}{ST} [/tex]
Cross-multiplying, we have;
[tex] 3ST = R(2S + T) [/tex]
Making R, the subject of formula;

A bus left Suva at 7.30am and arrived in Tavua at 11.00am. It covered a
distance of 350km. Fin the speed of the bus.
Answer:
100 km/hr
Step-by-step explanation:
11:00 a.m. less 7:30 a.m. works out to 3:30 hours (3 hours 30 minutes).
Then the speed of the bus was
350 km
--------------- = 100 km/hr, or about 62.5 mph
3.5 hrs
Answer:
100 km/hr
Step-by-step explanation:
Givens
T = 11:00 - 7:30
T = 3 hours 30 minutes
T = 3 1/2 hours
t = 3.5 hours
d = 350 km
Formula
d = v * t
Solution
350 km = v * 3.5 Divide by 3.5
350 km / 3.5 hours = v
350 / 3.5 = v
v = 100 km/hour

The equation of the quartic polynomial in standard form is,
⇒ f (x) = x⁴ - 27x² - 14x + 120
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
We have to given that;'
The function f(x) is a quartic function and the zeros of f(x) are -4,-3,2 and 5.
And, the leading coefficient of f(x) is 1.
Hence, We get;
The equation of the quartic polynomial in standard form is,
⇒ f (x) = 1 (x - (- 4)) (x - (- 3)) (x - 2) (x - 5)
⇒ f (x) = (x + 4) (x + 3) (x - 2) (x - 5)
⇒ f (x) = (x² + 7x + 12) (x² - 7x + 10)
⇒ f (x) = x⁴ - 7x³ + 10x² + 7x³ - 49x² + 70x + 12x² - 84x + 120
⇒ f (x) = x⁴ - 27x² - 14x + 120

int) A group of 10 hunters wait for ducks to fly by. When a flock of ducks flies overhead, the hunters all fire at the same time, each selecting a target at random and independently of the others. If each hunter independently hits his target with probability 0.4, and if all misses do not hit other ducks, what is the expected number of ducks that will be hit
Answer:
The expected number of ducks that will be hit is 4.
Step-by-step explanation:
For each hunter, there are only two possible outcomes. Either they hit a duck, or they do not. The probability of a hunter hitting a ducks is independent of any other hunter. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
A group of 10 hunters wait for ducks to fly by.
This means that [tex]n = 10[/tex]
Each hunter independently hits his target with probability 0.4
This means that [tex]p = 0.4[/tex]
What is the expected number of ducks that will be hit?
[tex]E(X) = np = 10*0.4 = 4[/tex]
The expected number of ducks that will be hit is 4.
A random sample of 388 married couples found that 294 had two or more personality preferences in common. In another random sample of 566 married couples, it was found that only 38 had no preferences in common. Let p1 be the population proportion of all married couples who have two or more personality preferences in common. Let p2 be the population proportion of all married couples who have no personality preferences in common.
Solution :
Given :
[tex]$n_1=388$[/tex] , [tex]$x_1 = 294, \ n_2 = 566, \ x_2 = 38$[/tex]
Sample proportion, [tex]$(\hat p_1)=\frac{x_1}{n_1}$[/tex]
[tex]$=\frac{294}{388}$[/tex]
= 0.7577
Sample proportion, [tex]$(\hat p_2)=\frac{x_2}{n_2}$[/tex]
[tex]$=\frac{38}{566}$[/tex]
= 0.0671
For 95 % CI, z = 1.96
The confidence interval for the population proportion,
[tex]$p_1-p_2=(\hat p_1-\hat p_2)\pm z \left\{\sqrt{\frac{\hat p_1 \times (1- \hat p_1)}{n_1}+\frac{\hat p_2 \times (1- \hat p_2)}{n_2}}\right\}$[/tex]
[tex]$=(0.7577-0.0671)\pm 1.96 \left\{\sqrt{\frac{0.7577 \times (1- 0.7577)}{388}+\frac{0.0671 \times (1- 0.0671)}{566}}\right\}$[/tex]
[tex]$=0.6906 \pm 1.96 \times \left 0.0241$[/tex]
= [tex]$0.6906 \pm 0.0472 $[/tex]
Lower limit : 0.6906 - 0.0472 = 0.6434
Upper limit : 0.6906 + 0.0472 = 0.7378

Triangles have 3 sidesThe sum of a triangle's interior angles will always be equal to 180°.Because we need the value of the triangle's interior angle, use the following formula to solve for x:
180 - x - y = zSince x and y are given, solve for z.180 - 129 - 23 = z28 = zz is the missing value, so for your problem, z is x.x = 28Which of the following statements is (are) correct?
I. At 6% interest, the present value of $400 for the first year, $600 for the second year, and $800 for the third year is $1,603.
II. The future value of the following mixed cash flow stream (if it is from an annuity due at 6% interest) $400 for the first year, $600 for the second year, and $800 for the third year is $1,999 (rounded).
Answer:
None OF THE STATEMENTS ARE CORRECT
Step-by-step explanation:
Present value is the sum of discounted cash flows
Present value can be calculated using a financial calculator
Cash flow in year 1 = $400
Cash flow in year 2 = $600
Cash flow in year 3 = $800
I = 6%
PV = 1,583.05
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
1583.05 x (1.06)^3 = $1885.44
None of the statements are correct based on the above calculations
To find the PV using a financial calculator:
1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.
2. after inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.
