Given:
The inequalities are:
\(-2<x<3\)
\(-2\leq x<2\)
To find:
The integer values that satisfy both inequalities.
Solution:
We have,
\(-2<x<3\)
\(-2\leq x<2\)
For \(-2<x<3\), the possible integer values are
\(x=-1,0,1,2\) ...(i)
For \(-2\leq x<2\), the possible integer values are
\(x=-2,-1,0,1\) ...(ii)
The common values of x in (i) and (ii) are
\(x=-1,0,1\)
Therefore, the integer values -1, 0 and 1 satisfy both inequalities.
Applicants for graduate school take a test that has scores which are normally distributed with a mean of 560 and a standard deviation of 90. What is the probability that a randomly chosen applicant will score between 500 and 600
To calculate the probability that a randomly chosen applicant will score between 500 and 600 on the test, we need to use the standard normal distribution.
We'll convert the given scores into z-scores and then find the corresponding probabilities using a standard normal distribution table or a statistical calculator. First, let's calculate the z-score for the lower boundary of 500: z1 = (500 - 560) / 90 = -0.667
Next, let's calculate the z-score for the upper boundary of 600:
z2 = (600 - 560) / 90 = 0.444. Now, we can find the probability associated with each z-score. Using a standard normal distribution table or a calculator, we find that the probability corresponding to z1 is approximately 0.2525, and the probability corresponding to z2 is approximately 0.6700.
To find the probability between these two boundaries, we subtract the lower probability from the upper probability:
P(500 < X < 600) = P(z1 < Z < z2) = P(Z < z2) - P(Z < z1) = 0.6700 - 0.2525 = 0.4175 Therefore, the probability that a randomly chosen applicant will score between 500 and 600 on the test is approximately 0.4175, or 41.75%.

To avoid the problem of not having access to Tables of F distribution when F values are needed for the lower tail, the numerator of the test statistic for a two-tailed test should be the one with the larger sample variance.
This is because the F-distribution is asymmetric and it is easier to find the F-value for the larger sample variance in the upper tail and then use the complement rule to find the F-value for the smaller sample variance in the lower tail. Sample size does not affect which numerator should be used in a two-tailed test.
To avoid the problem of not having access to Tables of F distribution when F values are needed for the lower tail, the numerator of the test statistic for a two-tailed test should be the one with the larger sample variance.

10. for which type of risk do you get rewarded with a higher expected return? a. systematic risk b. firm-specific risk c. diversifiable risk d. idiosyncratic risk
Systematic risk is the type of risk for which you can be rewarded with a higher expected return.
So, the correct answer is A
Systematic risk, also known as market risk or non-diversifiable risk, affects the entire market and cannot be eliminated through diversification.
Investors are compensated for taking on systematic risk through higher expected returns as they bear the fluctuations and uncertainties associated with the overall market.
In contrast, firm-specific, diversifiable, and idiosyncratic risks are specific to individual companies or industries and can be mitigated through diversification in an investment portfolio, so investors don't get rewarded with higher expected returns for these types of risks
Hence, the answer of the question is A.

The measures of the angles of a triangle are shown in the figure below solve for X
some examples include number of sides number of angles and parallel sides
Polygons are closed two-dimensional shapes with straight sides. They have various characteristics, including the number of sides, angles, and the presence of parallel sides. These properties help classify and identify different polygon shapes
The number of sides in a polygon determines its shape. For example, a triangle has three sides, a quadrilateral has four sides, and a pentagon has five sides. The number of sides can vary, and polygons with more sides are called n-gons, where "n" represents the number of sides.
The number of angles in a polygon is equal to the number of sides. Each vertex, or corner, of a polygon corresponds to an angle. For instance, a triangle has three angles, a quadrilateral has four angles, and so on. The sum of the interior angles of any polygon can be calculated using the formula (n-2) × 180 degrees, where "n" is the number of sides.
Parallel sides are a characteristic of specific types of polygons called parallelograms. Parallelograms have opposite sides that are parallel and congruent. This means they never intersect and are of equal length.
Understanding these properties of polygons allows for the identification and classification of different shapes based on their number of sides, angles, and the presence of parallel sides. These properties play a fundamental role in geometry and shape analysis.

An electrician purchases thirty 125-volt, 30-ampere, double-pole, double-branch cutouts listed at $6.40 per box of 5, less 25%, and 8 surface panels listed at $4.75 each, less 35%. Three percent is saved by paying the bill in 15 days. What is the cost of if paid within 15 days
The final cost if paid within 15 days is $51.91 ($53.52 - $1.61).
The electrician purchased 30 double-pole, double-branch cutouts listed at $6.40 per box of 5, with a 25% discount, and 8 surface panels listed at $4.75 each, with a 35% discount. If the bill is paid within 15 days, an additional 3% discount is applied.
First, we need to calculate the cost of cutouts and surface panels separately. For the cutouts, 30 cutouts are equivalent to 6 boxes (30/5). With the 25% discount, the price per box becomes $4.80 ($6.40 * 0.75). So, the total cost for cutouts is $28.80 (6 * $4.80).
For the surface panels, with the 35% discount, the price per panel becomes $3.09 ($4.75 * 0.65). The total cost for 8 panels is $24.72 (8 * $3.09).
Now, we add the costs together: $28.80 (cutouts) + $24.72 (panels) = $53.52. Lastly, we apply the 3% discount for paying the bill within 15 days, which is $1.61 ($53.52 * 0.03).

Step-by-step explanation:
the fourth term in the geometric sequence in part (a) appears as the $n$th term in the arithmetic sequence. find the value of $n$.
The value of n is 30.33. The thirty-fourth term can be found by solving for the common difference (d) and the number of terms (n) in the arithmetic sequence and then using the formula for the nth term of an arithmetic sequence.
Let's assume that the common ratio of the geometric sequence is r. Then, the terms of the geometric sequence are given by:
\(a_2 = a_1 * ra_{10} = a_1 * r^8a_{34} = a_1 * r^{32}\)
Since these terms also appear in the arithmetic sequence, we can write:
\(a_2 = a_1 + da_{10} = a_1 + 9da_{34} = a_1 + 33d\)
Substituting the expressions for a_2 and a_{10} from the geometric sequence into the arithmetic sequence, we have:
\(a_1 * r = a_1 + da_1 * r^8 = a_1 + 9d\)
Solving for d, we get:
\(d = a_1 * (r - 1)d = a_1 * (r^8 - 1) / 9\)
Next, we use the expression for a_{34} from the arithmetic sequence and substitute the expression for d to obtain:
\(a_{34} = a_1 + 33d = a_1 + 33a_1 * (r^8 - 1) / 9\)
Since the first term of the arithmetic sequence is 1, we have:
\(a_{34} = 1 + 33 * 1 * (r^8 - 1) / 9\)
The value of n can be found by using the formula for the nth term of an arithmetic sequence:
\(a_n = a_1 + (n-1)d\)
Setting n = 34 and substituting the expression for d, we have:
\(a_{34} = 1 + (33) * (a_1 * (r^8 - 1) / 9)\)
So the thirty-fourth term of the arithmetic sequence is:
\(a_{34} = 1 + 33 * (1 * (r^8 - 1) / 9) = 34 - 33/9.\)

Answer:
£20.44
Step-by-step explanation:
Step 1: find the area of the total area of the garden.
Total area = l*w
Where,
l = 10 m
w = 6 m
Total area of garden = 10*6 = 60m²
Step 2: find the area of the vegetable patch.
Area of vegetable patch = l*w = 2*1.5 = 3m²
Step 3: find the area covered by pond.
Area covered by pond = πr²
Take π as 3.14
r = 2m
Area of pond = 3.14*2² = 12.56 m²
Step 4: find the area of the remainder of the garden to be reseeded.
Area of the remainder of the garden = total area of the garden - (area of the vegetable patch + area of pond)
= 60 - (3 + 12.56)
= 60 - 15.56
Area of the remainder of the garden = 44.44 m²
Step 5: calculate the total cost to reseed the garden.
Given that a bag of seed to cover 10m² is £4.60, total cost to reseed the remainder of the garden measuring 44.44 m² can be calculated bas follows:
10 m² = £4.60
44.44 m² = \( \frac{44.44*4.60}{10} = 20.44 \)
The answer is £20.44

Mary and John’s bill at a restaurant is $20.00. How much money should they leave as a tip if they plan to tip 15%?
ANSWER: For percents,this is always done by simply dividing the percent (in this case 15%) by 100%. So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number. 0.15 x $20.00=$3.00. So, the amount of tip you are going to leave is $3.00
Leave a tip of $3.00 on a $20.00 bill is an appropriate gesture for a 15% tip based on appropriate percentage.
Leaving a tip for good service at a restaurant is a common practice, and it shows appreciation and respect for the hard work of the staff. Mary and John's bill at a restaurant is $20.00, and they plan to leave a 15% tip for the server based on percentage.
To calculate the tip amount, we need to convert the percentage into a decimal form by dividing it by 100. Therefore, 15% becomes 0.15 in decimal form. Multiplying this decimal value by the total bill amount of $20.00 gives us the tip amount, which is $3.00.
It is important to note that while tipping is a customary practice, it is not mandatory. The amount of the tip is also subjective and may depend on various factors such as the quality of service, the atmosphere of the restaurant, and the level of satisfaction of the customer. However, a general rule of thumb for good service is to leave a tip of 15% to 20% of the total bill amount.
In conclusion, a $3 tip on a $20 note is a suitable gesture for a 15% tip. It is a modest gesture to thank the server for their hard work and recognize their efforts in making the dining experience enjoyable.
