Minute hand completes 1 round in 60 minutes

1 round =[tex]360^{\circ}[/tex]

So, The minute hand covered degrees in 60 minutes = [tex]360^{\circ}[/tex]

The minute hand covered degrees in 1 minute [tex]= \frac{360^{\circ}}{60^{\circ}}[/tex]

Phillip watched a beach volleyball game from 1 P.M. to 1:20P.M.

So, He watched it for 20 minutes

So,The minute hand covered degrees in 20 minutes =[tex]\frac{360^{\circ}}{60^{\circ}} \times 20 =120^{\circ}[/tex]

Hence The minute hand covered 120 degrees

Step-by-step explanation:

The larger number is 37 and the smaller number is 25.

To solve this problem, let's assume that the larger number is x and the smaller number is y.

According to the problem, x - y = 12 and 4x - 25 = 48 + 3y. We can solve this system of equations by substituting the value of x from the first equation into the second equation.

Therefore, the larger number is 37 and the smaller number is 25.

Answer:

The proposed way of sampling is a biased way to perform the survey.

Step-by-step explanation:

Convenience sampling is a kind of non-probability sampling method that comprises of the sample being taken from that portion of the population that is near to hand.  In this type of sampling method, all items doesn’t have an equivalent chance of being selected, which doesn’t comprises of random collection of items.

Convenience sampling is where we take in items which are easy to reach.

Convenience sampling consists of selection bias, i.e.e the bias involved in the sample due to inappropriate selection procedures.

For example, randomly selecting 4 people sitting near him to guesstimate the mean age of the class is a convenience sampling example. or gathering information on customer satisfaction by interviewing 6 randomly selected customers from a local store is an illustration of convenience sampling.

In this case, the sample suggested by the students consists of surveying the first 100 people who enter the school, about the public opinion on a school building project.

This is an example of convenience sample.

So, there is a selection bias present in the sample.

Thus, the proposed way of sampling is a biased way to perform the survey.

Answer:

By year 2092

Step-by-step explanation:

In this question, we are asked to calculate the year at which the population of the city will reach 178,000

The equation that models the population of the city is given as;

A = 119e^0.027t

Here, we plug A to be 178,000

178000 = 119e^0.027t

we take the natural logarithm of both sides)

ln 178,000 = ln (119e^0.027t)

12.09 = 0.027t ln 119

12.09/ln 119 = 0.027t

2.53 = 0.027t

t = 2.53/0.027

t = 93.7 which is approximately 94 years

Since t is number of years after 1998, the exact time the population will reach 178,000 will be 1998 + 94 years = 2,092

Answer:

The population of the city will reach 178 thousand almost 15 years after 1998, that is, in the last months of 2012.

Step-by-step explanation:

The equation to be solved is:

[tex]178 = 119\cdot e^{0.027\cdot t}[/tex]

Now, the variable is cleared with the help of algebraic handling:

[tex]\frac{178}{119} = e^{0.027\cdot t}[/tex]

[tex]\ln \frac{178}{119} = 0.027\cdot t[/tex]

[tex]t = 37.037\cdot \ln \frac{178}{119}[/tex]

[tex]t \approx 14.913\,yr[/tex]

The population of the city will reach 178 thousand almost 15 years after 1998, that is, in the last months of 2012.

Answer:7 sr 2

Step-by-step explanation:

The length of side GH in an isosceles right triangle where angle G is 45 degrees and side HI is the hypotenuse equal to 7, is 7/√2 or 7√2/2 when rationalized.

You asked about finding the length of side GH in a right triangle where angle G equals 45 degrees, and side HI equals 7. In an isosceles right triangle, the lengths of the two legs are equal. As angle G is 45 degrees, it indicates that triangle GHI is an isosceles right triangle. Using the concept that in such a triangle, the lengths of the legs are equal, since they correspond to the sine and cosine of 45 degrees, which both equal 1/√2.

Given that HI is the hypotenuse and GH is one of the legs, we can use the relationship between the sides: GH = HI * cos(45°) = 7 * 1/√2. Therefore, the length of side GH is 7/√2 or 7√2/2 when rationalized.

did the question on test

The visiting team took fewer shots than the home team, as inferred by comparing the medians represented by the line in each box plot.

When comparing the medians of the two data sets from the box plots provided by a hockey coach, an inference that can be made is that the visiting team took more shots than the home team. This is determined by comparing the median number of shots, which is indicated by the line dividing the box within each box plot. For the home team, the median is at 22 shots, while for the visiting team, the median is at 18 shots. Since the median represents the middle value of the data set, having a lower median suggests that the visiting team took fewer shots on average than the home team.

Answer:

-((2x - y) (3x + y))

Step-by-step explanation:

The correct statement is

The data is skewed right.

The lower and upper quartiles are shown on the left and right sides of a box and whisker plot, respectively. The interquartile range, which contains 50% of the data, is covered by the box. The median is the vertical line that divided the box in half.

We have a box and whisker plot.

Based on the position of the median value in the box plot, we may decide if a distribution is skewed or not. The distribution is right-skewed (or "positively" skewed") when the median is closer to the bottom of the box and the whisker is shorter on the lower end of the box.

A right-skewed distribution with a positive skewness is one in which the median is smaller than the mean. The median of a left-skewed distribution is bigger than the mean when the skewness is negative, on the other hand.

Here, the data is shorter on the lower end of the box.

Thus, the plot is positively skewed.

Step-by-step explanation:

We can find the slope given two points by using the following formula

m = (y2-y1)/(x2-x1)

    = (-4 - -2)/(-4 -4)

   = (-4+2)/(-4-4)

   = -2/-8

  = 1/4

Answer:

I think the slope is 1/4

Step-by-step explanation:

if you use the slope equation y1-y2/x1-x2, then you get (-2 - -4)/(4 - -4), which is 2/8, which is 1/4

Answer:

karlen predicted it will take 1.7 hours longer than he actually did

Step-by-step explanation:

If Karlen started painting the walls at 10:45 am, and he said that he could complete the job at 5:25 pm.

Which means he thought he would spend 6 hrs 40 minutes or 6⅔ hours or 20/3

Now, his father said ⅝ of that time was going to be enough to paint the whole wall.

Thus; estimated time by father to paint whole wall = ⅝ x 20/3 = 25/6 hours.

Now, it says karlen took 80% of an hour longer than the time predicted by his father to finish the painting.

Thus, karlen actually spent;

25/6 + 80/100 hours = 25/6 + 4/5 = 149/30 hours

Thus, since karen predicted he was going to spend 20/3 hours, the difference is;

20/3 - 149/30 = 1.7 hours

So karlen predicted it will take 1.7 hours longer than he actually did

Answer:Para pasar el número decimal 1.83333 a fracción, siga los siguientes pasos:

Paso 1: Escriba el número como una fracción de 1 (uno):

1,83333 = 1,83333/1

Paso 2: Multiplica simultáneamente el numerador y el denominador por 10 tantas veces cuánto los dígitos después de la coma (separación entre la parte entera y la parte fraccionaria del número):

Como tenemos 5 números después de la coma, multiplique el numerador y el denominador por 100000. Así,

1,83333/1 = (1,83333 x 100000)/(1 x 100000) = 183333/100000.

Tenga en cuenta que multiplicar por 10 es el mismo que desplazar la coma a la derecha una posicion.

Una vez que esta fracción es irreductible, es decir, está en forma reducida, ya no podemos simplificarla. La respuesta es la fracción anterior.

Como el numerador es mayor que el denominador, tenemos una fracción IMPRORIA, entonces podemos expresarla como un NÚMERO separación, así 183333/100000 también es igual a 1 83333/100000 cuando se representa por un número mixto.
