Step-by-step explanation:
5⁴(3406 - 867) + (1.9 x 6)
=625(2539) + 11.4
= 1586875 + 11.4
=1586886.4
Answer:
= 1586886.4
Step-by-step explanation:
5^4 = 5 x 5 x 5 x 5
= 625
625(3406 - 867)
625 x 3406
= 2128750
625 x 867
= 541875
2128750 - 541875
= 1586875
1.9 x 6
= 11.4
1586875 + 11.4
= 1586886.4

A snowboarding competition site is using a new design for the parallel giant slalom. The designer of the slalom is investigating whether there is a difference in the mean times taken to complete a run for men and women competitors. As part of the investigation, independent random samples of men and women who will use the slalom run are selected and their times to complete a run are recorded. Which of the following is the appropriate inference procedure by which the designer can estimate the difference in the mean completion times for men and women?
i. A one-sample I-Interval for a sample mean e-sample interval for a population mean
ii. A matched para tantervil for a meen difference
iii. A two-sample -interval for a difference between population means
iv. A two-sample t-interval for a difference between sample means
Considering that we have two samples, and the standard deviation for each sample, the correct test is given by:
iii. A two-sample -interval for a difference between population means.
When to use a t-test and a z-test?If we have the standard deviation for the sample, the t-test is used.If we have the standard deviation for the population, a z-test is used.Here, there are two samples, and we will investigate their difference. The information taken from the sample is expanded to the population, and since we have the standard deviation for each sample, a t-test is used, hence the correct option is given by:
iii. A two-sample -interval for a difference between population means.

This figure represents a compartment in a container for storing sewing supplies. Another compartment is identical except that it is 3 centimeters taller. What is the difference in volume of the two compartments? Enter your answer in the box.
The difference in volume of the two compartments is 210 cm³
What is volume?
Volume is the amount of space occupied by a three dimensional shape or figure.
The volume of the compartment = area of base * height
Area of base (trapezoid) = (1/2)(sum of parallel side)(height) = (1/2) * (15 + 5) * (7) = 70 cm²
Volume of compartment = 70 * 8 = 560 cm³
For the new compartment, height = 8 + 3 = 11 cm, hence:
Volume of new compartment = 70 * 11 = 770 cm³
Difference in volume = 770 cm³ - 560 cm³ = 210 cm³
The difference in volume of the two compartments is 210 cm³

An art gallery owns a painting that is valued at $37,000. The gallery owner estimates that its value will increase by 10% every year. If the owner is correct, then how much will it be worth in 4 years?
Answer: $51,800
Step-by-step explanation:
if the value increases by 10% every year, we can represent this as a linear function, in the form:
y = mx + b
y = [0.1(37,000)]x + 37,000
0.1 x 37000 represents the 10% increase per year, and x represents the number of years that have passed. we add 37,000 at the end to represent the original cost of the painting.
we can simplify the 0.1(37,000) to 3700, which is how much the painting's cost should increase per year. so our equation is:
y = 3,700x + 37,000
So, in 4 years, the painting will be worth:
y = 3,700(4) + 37,000
14,800 + 37,000
$51,800

Step-by-step explanation:
inequalities follow basically the same rules as equalities (ahem, equations). for creation and calculation.
you just indicate whole areas above or below given lines.
behind every inequality is a "normal" equation that defines the delimiter.
the question already tells us which variables to use.
x = number of hot dogs
y = number of peanuts (I guess, bags of peanuts)
he wants to buy at least 4 snacks.
hmmm.
what would you do, if the question asked us :
he wants to buy 4 snacks.
what did you learn from the previous questions ?
the equation would be
x + y = 4.
but now it asks us about "at least" 4 snacks. so every solution, 4 or more, is valid. not only 4.
so, the inequality is
x + y >= 4
and he has $20 to buy these snacks.
again, with equations we would have said
3x + 2y = 20
remember, a hot dog costs $3, a bag of peanuts costs $2. so, every single hot dog and every single bag of peanuts brings itself into the cost calculation with that amount.
x hot dogs cost $3x. y bags of peanuts cost $2y.
but here, we are now flexible. he can spend $20, but he does not have to fully exceed his budget. he can also spend less.
so, the inequality is
3x + 2y <= 20
together these inequalities now describe the situation that he cannot spend more than $20, but he can spend as little as he wants, as long as he gets at least 4 snacks.
all combinations of x and y values that satisfy these conditions are valid solutions.
the actual solution would be then more complex, as the real life scenario gives us more constraints :
0 <= x <= 6 (because with more than 6 hot dogs alone he would already bust his budget).
0 <= y <= 10 (after buying 10 bags of peanuts the $20 are gone).
that eliminates the negative value solutions that the basic 2 equations would allow.
Jane made a poster that had a length: 1 2/3 of feet and a width: 5/6 of feet. What is the perimeter of her poster?
Answer:
P = 6 2/3 ft
Step-by-step explanation:
The formula for the perimeter of a rectangle of length L and width W is
P = 2(L + W).
Here the perimeter is P = 2(1 2/3 + 5/6) = 2(5/2 + 5/6)
= 2(15/6 + 5/6) = 2(20/6)
= 40/6 = 20/3
P = 6 2/3 ft
is the sum of interior angles the same if the polygon if irregular or not
say a hexagon and a irregular hexagon might have the same interior angle sum
Answer:
Yes, it would still be considered a hexagon. The reason why we require "6 angles" is probably just because you don't want the 6 lines to cross and create "more than 6 angles". The hexagons you are probably thinking of (the one with all the angles and sides equal) would be regular hexagons.

high speed train travels at a speed of 200 km/h if the train sets off from station A at 12 24 and reaches station B AT 14 12 find the distance in between two stations giving your answer in meters.
Answer: 360000m
Step-by-step explanation:
Okay, so since we know that this train’s speed is 200km/h, let’s find the time difference between 12 24 and 14 12.
14 12 - 2hrs = 12 12
12 12 + 12min = 12 24
2hrs -12min = 1hr 48 min
1hr 48 min also equals to 1.8hrs in decimals. So:
200km x 1.8 = 360km
Now we have to find the answer in meters. Since 1km is equal to 1000m,
That means 360km equals 360000m.
Therefore 360000m is the answer
Answer pleaseee!!!!
