Answer:

you're given a *rate* of decrease and then the *extent* of the "cause". SO the rate is 10C/1000m (right? You understand why this is a rate? You go 1000m up, the temperature drops 10C. And it happens continually, bit by bit, as you climb. That's a rate!

But, you don't stop with climbing just 1000m: you climb 1000m twice *more*. So, how much has the temperature dropped in all, by the end?

You really should be able to put this together as 10C/1000m  x  3000m  = result. It will be in units of (degrees) C.

Now, finish the problem and get down the mountain, before you freeze (also, winds kick up more on mountains -- a double whammy).

Step-by-step explanation:

The probability that AT LEAST ONE of them has been vaccinated is 0.9979.

Vaccination rate among the population: p = 0.71

Sample size = 5

Assume that X people have received vaccinations.

P(atleast one) = 1 - P (none)

By the binomial distribution, now,

P(none)= (⁵₀) 0.71° (1-0.71)⁵⁻⁰

             = 1 × 1 (0.29)⁵

            = 0.0021

So,                

P(at least one) therefore equals 1 - P (none)

                        = 1 - 0.0021

                        = 0.9979

Therefore, the probability that AT LEAST ONE of them has been vaccinated is 0.9979

Genevieve lost more than 33 points in her turn at a video game.

Absolute value describes a number's distance from zero on the number line without taking direction into account. A number's absolute value is never negative.

Given that Matthew's score is −33 points.

In Genevieve’s turn, she scored lesser points than Matthew in her turn at a video game.

Let y be the points scored by Genevieve.

Then we have y < -33

⇒ | y | > | -33 | (Using absolute value on both sides)

⇒ | y | > 33

The absolute value of y can be any number greater than or equal to 34, while Genevieve's point in her video game turn is less than or equal to -34.

Therefore, Genevieve lost more than 33 points in her turn at a video game.

The toll of death per day in 2015 is 91.

We are given the approximate number of people who died in year 2015, which is 33,200. Now, as per the known fact, the year 2015 has 365 days. So, we can easily calculate the toll in deaths per day by performing division.

Number of deaths in 365 days = 33,200

Number of deaths each day = 33,200 ÷ 365

Performing division to find the number of deaths per day

Number of deaths each day = 90.96

Rounding off the digits to find number of deaths each day

Number of deaths each day = 91

Hence, this toll in deaths per day is 91.

Answer:

Step-by-step explanation:

83 1/3% =

= (83 + 1/3)%      <------- the mixed numeral 83 1/3 is the same as 83 + 1/3

= (249/3 + 1/3)%    <---- to add 83 + 1/3, use the common denominator 3

= 250/3 %      <---- the sum of 83 and 1/3 is 250/3, but this is still percent

= (250/3) / 100    <---- to change percent to decimal, divide percent by 100

= 250/300    <---- now we need to reduce this fraction

= 25/30    <---- divide numerator and denominator by 10

= 5/6    <---- divide numerator and denominator by 5

The larger angle is 67.5°.

When two angles add up to 90 degrees, they are complimentary.

Let L be the larger angle and S be the smaller angle

Given, smaller angle is 1/3 of larger angle

Thus, S = L/3

But, L + S =90

L + (L/3) =90

4L/3 = 90

4L = 270°  .Therefore, L = 270 / 4 = 67.5°.

Thus the larger angle is 67.5°.

Which angle is wider?

Right angles (90 degrees), acute angles (smaller than a right angle), and obtuse angles are the three types of angles that we can recognize (larger than a right angle).

This happens because as there is an increased demand for the number of bedrooms in a home there should be enough supply in the market to fulfill the requirements. So, there should be a surplus of beds in the market and for that the selling price increases to maintain the surplus.

A box can hold up to 15 items ensuring that every box contains the same quantity of items.

Given there are 10 rulers and 25 packages of tape.

Only one type of item may be present in each box.

Simply put, probability is the likelihood that something will occur.We can discuss the chance or likelihood of various outcomes when we don't know how an event will turn out. Statistics is the study of events that follow a probability distribution.The chance of an event happening is equal to 1 if there is no doubt about its likelihood. In other words, there is a 1 in the chance of an event. An event's probability is zero if there are no chances that it will occur.

In the event when 25 packages of tape and 10 rulers have to be placed in a box, the answer is 25 - 10 = 15.

then only 15 items that can be placed in a box so that each box has the same number of items.

Answer:

111 feet

Step-by-step explanation:

The scale used to blow up the the lead singer (and the band) is

2 in : 3 feet

==> 1 in : 3/2 feet

Let X be the height of the band leader in inches and the blown-up image be Y

X = 6' 2" = 6 x 12 + 2 = 72 + 2 = 74"

Then Y = (3/2) x H

Y = (3/2) x 74" = 111 feet

Both the shapes will have the same Perimeter.

It is given that :

Anthony drew a pentagon whose each side measures 6inches

Whereas, Carol drew a hexagon whose each side measures 5inches

The formula to calculate the Perimeter of the Pentagon is: 5*a

and, the formula to calculate the Perimeter of the Hexagon is: 6*a

In the given formulas, 'a' represents the measure of the side for both the Pentagon & Hexagon.

Calculating, Perimeter of Pentagon P1 = 5 * a, where a = 6 inches

                         => P1 = 5*6  => P1 = 30inch

Calculating, Perimeter of Hexagon P2 = 6*a, where a = 5 inches

                         => P2 = 6*5 => P2 = 30inch

We get P1 = P2
Hence, Both the Pentagon & the Hexagon have equal Perimeters of 30inch

Answer:

The answer is B, Domain: −2≤x≤2 Range: −2≤y≤3

Step-by-step explanation

Solution :

the differences in the X coordinates and Y coordinates:

The x-coordinate tells you how many steps you have to take to the right (positive) or left (negative) on the x-axis. And the y-coordinate tells you have many steps to move up (positive) or down (negative) on the y-axis.

Given : difference in the x-coordinates of two points is 3

the difference in the y-coordinates of the two points is 6

The slope of the line :

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in the y-coordinate is represented by Δy and the net change in the x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

Tan θ = Δy/Δx can also represent the slope of the line

So, tan θ to be the slope of a line.

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The letter ‘ m’ usually represents the slope.

If P(x1,y1) and Q(x2,y2) are the two points on a straight line, then the slope formula is given by:

Slope,

m = Change in y-coordinates/Change in x-coordinates

m = (y2 – y1)/(x2 – x1)

Therefore, based on the above formula, we can easily calculate the slope of a line between two points.

In other terms, the slope of a line between two points is also said to be the rise of the line from one point to another (along the y-axis) over the run (along the x-axis). Therefore,

Slope, m = Rise/Run

Use the slope formula.

the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or

the change in the y values over the change in the x values.

The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2. It does not matter which point you label as the first point and which you label as the second. Don't forget to include the correct sign of each value. Simplify to get the value of the slope. Check the your answer by graphing the points and verifying that the vertical distance between the two points and the horizontal distance between the two points is captured by the numerator and denominator of the slope
