Answer:

C

Step-by-step explanation:

Ms. Barcht's savings account can be modeled with the expression

50 + 25x

Mrs. Greene's savings account can be modeled with the expression

75x

Since the question is how many weeks Mrs. Greene will have more money than Ms. Bracht. we use an inequality to contain the all the solutions.

Mrs.Greene > Ms. Bracht

75x > 25x + 50

Answer:

The answer would be C. 75x>25x+50

Step-by-step explanation:

The answer would be C. because Ms. Barcht started with $50 and deposits $25 every week while Mrs. Greene saves $75 a week. 7 days is a week so lets multiply $25 x 2 (2 weeks). Ms. Barcht would have $100 by the end of 2 weeks and Mrs. Greene would have $150 by the end of 2 weeks because $75x2 is $150

Hope this helps.

Both of the given equations have no solution.

1. sec x-tanx sinx = 1/sec x

The left-hand side of the equation can be simplified by using the identity that sec(x) = 1/cos(x) and tan(x) = sin(x)/cos(x). So,

sec x - tan x sin x = 1/cos x - sin x/cos x sin x = 1/cos x - sin^2 x/cos x = 1/cos x - (1-cos^2 x)/cos x = 1/cos x - (1/cos x) = 1/cos x - 1/cos x = 0.

On the right-hand side, sec x = 1/cos x, so 1/sec x = cos x. Hence,

0 = cos x

This equation has no solution, which means that the original equation sec x - tan x sin x = 1/sec x has no solution.

2. 1 +cosx/sinx = csc x Cot x

We can simplify the left-hand side of the equation by using the identity that csc(x) = 1/sin(x) and cot(x) = cos(x)/sin(x). So,

1 + cos x/sin x = 1/sin x * cos x/sin x = cot x.

Hence,

1 + cot x = cot x

This equation has no solution, which means that the original equation 1 +cosx/sinx = csc x Cot x has no solution.

Congruence exists between all angles, whether they are exterior, interior, alternative, or matching.

From this in-depth examination we aimed to draw out some of the key ... closely their business case and employ model makers to create a 3D prototype.

Step-by-step explanation:

The electrician needs approximately 296.26 feet of wire.

The links between triangle's sides and angles are studied in the mathematic discipline known as trigonometry. It entails an examination of triangle's angles, lengths, and areas as well as their angles' mathematical properties (such as sine, cosine, and tangent).

The situation described can be modeled as a right triangle, where the wire from the electric box to the pole is the hypotenuse, and the angle of elevation is one of the acute angles. Let x be the length of the wire needed in feet.

Using trigonometry, we can write:

sin(17°) = opposite / hypotenuse

where the opposite side is the height of the connection on the pole above the ground. We can solve for the hypotenuse (the length of wire needed) as follows:

hypotenuse = opposite / sin(17°)

To find the opposite side, we can use the fact that the angle of elevation is 17° and the distance from the pole to the point on the ground directly beneath the connection is 85 feet. This distance is the adjacent side of the triangle, so we can write:

tan(17°) = opposite / 85

Solving for the opposite side, we get:

opposite = 85 tan(17°)

Substituting this into the formula for the hypotenuse, we get:

hypotenuse = (85 tan(17°)) / sin(17°)

hypotenuse ≈ 296.26 feet

Therefore, the electrician needs approximately 296.26 feet of wire.

Main AnswerIn the study by Hoynes (2012), the population that is of interest to the researchers are families who receive Supplemental Nutrition Assistance Program (SNAP) or more commonly known as food stamps. The study examines the impact of the policy-driven change in economic resources available in utero and during childhood on the economic health of individuals in adulthood.

The sample that the study examines are 60,782 families over the time period of 1968 to 2009, which is subsequent to the introduction of the Food Stamp Program in 1961. The data links family background in early childhood to adult health and economic outcomes.The characteristics of the population that are of interest to the researchers are the impact of a positive and policy-driven change in economic resources available in utero and during childhood on the economic health of individuals in adulthood. Specifically, the researchers looked at the long-term effect of access to food stamps in childhood on the incidence of metabolic syndrome (obesity, high blood pressure, and diabetes) and an increase in economic self-sufficiency for women.

Based on the study, the researchers concluded that access to food stamps in childhood leads to a significant reduction in the incidence of metabolic syndrome and, for women, an increase in economic self-sufficiency. Hence, the results suggest substantial internal and external benefits of SNAP.

Using the concept of bias, it is found that the correct option is:

(A)  Employees may not want to give critical feedback in person to their manager, so this is likely an  overestimate of Valerie's performance.

Samples have to be well chosen, otherwise, there can be a source of bias. For example, if you want to make a survey about who is better, Pele or Maradona, if you choose only Brazilians, or only Argentinians, the results will be biased, thus a sample with an equal number of Brazilians and Argentinians should be used.

In this problem, Valerie's is their manager, and the employees may be reluctant to give her critical feedback, which means that the proportion of 83% is an overestimate, and the correct option is:

  an = a1 +d(n -1)

The least active 20% of the mildly obese individuals spend at most 317 minutes walking or standing.

To find the number of minutes that the least active 20% of the mildly obese individuals spend walking or standing, we need to use the normal distribution. The normal distribution is a continuous probability distribution that is defined by the mean and standard deviation. In this case, the mean is 373 minutes and the standard deviation is 67 minutes.

To find the number of minutes that corresponds to the least active 20% of the mildly obese individuals, we need to find the 20th percentile of the normal distribution. The 20th percentile is the value below which 20% of the observations fall.

We can use the standard normal distribution table or a normal distribution calculator to find the 20th percentile. The standard normal distribution table gives the probabilities for the standard normal distribution, which is a normal distribution with a mean of 0 and a standard deviation of 1. To use the standard normal distribution table, we need to standardize the normal distribution by converting the minutes to standard units.

To standardize the normal distribution, we can use the following formula:

z = (x - mean) / standard deviation

where z is the standard unit, x is the number of minutes, mean is the mean of the distribution (373 minutes in this case), and the standard deviation is the standard deviation of the distribution (67 minutes in this case).

Plugging in the values, we get:

z = (317 - 373) / 67

= (-56) / 67

= -0.836

Looking up -0.836 in the standard normal distribution table, we find that the corresponding probability is 0.20. This means that the 20th percentile of the normal distribution is at -0.836 standard units or 317 minutes.

Therefore, the least active 20% of the mildly obese individuals spend at most 317 minutes walking or standing.
