Carlisle is testing different types of planting soil to determine which type is most effective in growing blueberry bushes. He purchases 2 different brands of planting soil from a local store. Carlisle applies Brand A to an area of the yard that receives full sunlight and Brand B to another area of the yard that is in partial shade. He waters both areas daily. At the end of the study, Carlisle concludes Brand A is more effective in growing blueberry bushes. Why is his conclusion not valid?

Answers

This conclusion is not valid because BOTH SOIL BRANDS WERE NOT SUBJECTED TO THE SAME CONDITIONS. 
Carlisle applied brand A to the part of the yard that received full sunlight while brand B was applied to the area of the yard which received partial sunlight. This implies that the soils were subjected to different conditions and this ought not to be so, since sunlight is a very important factor, which the soils need.
His conclusion is not valid because his dependent variables weren't the same. When testing out an independent variable, which is the soil in this case, all the other factors of the experiment has to remain the same in order to provide a correct conclusion. Since Carlisle was testing out two different types of soils, he had to set all the other conditions of the plants exactly the same, including the amount of lights that the plants receive. Brand B received full sunlight whereas brand A received less. This could definitely have impaired the results of this experiment, therefore, making it invalid.

At a certain time of day the angle of elevation of the sun is 30 a tree has a shadow that is 25 feet long find the tree to the nearest foot

Answers

If we draw out this scenario, we can see that it is a 30-60-90 right triangle, and the tree shadow is the leg opposite of the 60 degree angle. The problem asks for the length of the tree, which is the leg opposite of the 30 degree angle. In a 30-60-90 triangle, the leg opposite of the 30 degree angle has length “x”, and the leg opposite of the 60 degree angle has length “x times sqrt 3” (or “x rad 3”). We know the leg opposite of the 60 degree angle is 25 feet, so we can setup the equation “x rad 3 = 25”. We divide sqrt of 3 on both sides and end up with “x = 25/sqrt 3”. The problem asked for the leg opposite of the 30 degree angle, which we set as “x”. The problem asks for the length to the nearest foot. When put into a calculator, “25/sqrt 3” ends up being about 14 feet, which is our final answer.

a motorboat travels 432 kilometers on 6 hours going upstream and 384 km in 4 hours going downstream. What is the rate of the boat in still water and what is the rate of the current.
please help slove and steps

Answers

Going upstream: 432 km / 6 hours = 72 km/h
Going downstream: 384 km / 4 hours = 96 km/h
Going upstream against the current means that the effective speed is:
r_boat - r_current = 72
Meanwhile, going downstream with the current means;
r_boat + r_current = 96
Adding both equations (to cancel out r_current) gives:
2r_boat = 72 + 96
r_boat = 84 km/h
Substituting back into one of the original equations: r_current = 12 km/h.

Samples of size n = 9 are selected from a population with μ = 80 with σ = 18. what is the expected value of m, the mean of the distribution of sample means?​

Answers

Answer: 
80

Explanation:
The mean of the distribution of sample means always target the population mean. What this line tells is that whatever the population mean will be, the mean of the distribution of sample means will be same. Since the population mean is 80, the mean of distribution of sample means will also be 80.

However, the standard deviation of the sample distributions is different and is equal to the population standard deviation divided by square root of sample size. So in this case the standard deviation of distribution of sample means will be 6 .

Re-arranging the inequality to find the test points:

This means, we need to test the inequality for x = -10, x = 0 and x = 7

Since question assumes that x > 0, so we ignore the values less than 0.
So the test points are x = 0 and x = 7

At x = 0 the expression is undefined.
Between x = 0 and x = 7 the value of expression [tex] \frac{(x-7)(x+10)}{x}[/tex] is negative. At x = 7 the value of expression is 0. Above x = 7 the value of expression is positive.

round 543,873 to nearest ten thousand

Answers

For this case we have the following number.
 543,873

 1) Remember that when rounding the number to the nearest tousand, the number must have the first three digits (from right to left) equal to zero.

 2) The fourth digit of the number (from right to left) must be rounded to the next number only if the third digit (from right to left) is greater than or equal to 5.

 3) Following steps 1) and 2) we have the number rounded to the nearest tousand is:544,000

 Answer:
 Round to the nearest tousand:
 544,000

Final answer:

To round 543,873 to the nearest ten thousand, we assess the digit in the ten thousand's place (4) and the digit to its right (3). Since the latter is less than 5, we round down, resulting in 540,000.

Explanation:

The question asks to round the number 543,873 to the nearest ten thousand. To do this, we look at the digit in the ten thousand's place, which is 4, and then look at the digit to its right, which is 3. If the digit to the right is 5 or above, we would round up. However, since it's less than 5, we round down. Therefore, 543,873 rounded to the nearest ten thousand is 540,000.

-4x-2y=-12 and 4x+8y=-24 using addition/eliminatin method

Answers

Use the elimination method:

-4x - 2y = -12
+4x + 8y = -12
--------------------
 0  + 6y = -24

6y = -24
6y/6 = -24/6
y = -4

Plug in -4 for y in one of the equations
-4x - 2y = -12
-4x - 2(-4) = -12
-4x + 8 = -12
-4x + 8 (-8) = -12 (-8)
-4x = -20
-4x/-4 = -20/-4
x = 5

x = 5, y = -4

hope this helps
elimination method is best because one equation has 4x and the other has -4x. Add the two equations together.

 -4x - 2y = -12
+4x + 8y = -24
----------------------
   0 + 6y = - 36

divide by 6 both sides 
y = -6 

use this to find x in either equation.
4x + 8(-6) = -24
4x  - 48 = -24
4x = -24 + 48
4x = 24
x = 6

Imagine a world in which only decimal,not fractions,are used.how would your life be different

Answers

This answer depends a bit on your age, the types of activities you partake in and the kind of work you do/are planning to do but here goes:

I am thinking of some uses of fractions where decimals are not typically used. One might be cooking. Often the ingredients (1/2 cup of four and so on) are measured using fractions. If you were in a world with decimals you might need to make (1/3) the servings of a recipe that calls for 1/4 of a cup of some ingredient and instead of 1/12 have to deal with a long repeating decimal that probably would need to be approximated so would not be precise.

While on the subject of food ordering pizza (1/2 with pepperoni, 1/4 mushrooms and 1/4 plain) would be doable after you got used to it but probably not as comfortable. Dividing up slices of pizza among friends (one slice is usually 1/8 of a pie) might be awkward though eventually doable.

Estimation - the biggest issue is exactitude versus estimation. When we use a fraction like 1/3 that is an exact value, but when we use .333 or .3333333 no matter how many 3s we use we are only estimating because the 3s go on forever and we can't write them forever. Yes, we can use .3 (with a bar over the 3, but now try to multiply that with .456565656 with a bar over the 56. This becomes practically impossible unless we estimate ... so the biggest issue would be that you would lose precision in many calculations and measurements and have to deal with answers that are good enough (but not exact).

Now say you work on some major car company or you design bridges or you are a scientist developing medicine that cures diseases, would not you want the ability to measure and compute precisely? If I split the pizza up wrong it is not a big deal. If I use a little more flour or a little less than I should in the recipe it might not make much of a difference in the end but if I am doing something that impacts the health, safety or well being of another human being, I would not want to live in a world where I have to estimate and can't count on having the exact, precise value.

Then take the absolute value of the expression in the square bracket.

Liliana used 4 dark power crystals to raise 14 zombie soldiers. She wants to know how many zombie soldiers (z) she can raise with 10 dark power crystals. How many zombie soldiers can Liliana raise with 10 power crystals?

Answers

4c = 14z.
1c = 3.5z.
10c = 35z.
So she can raise 35 with 10 power crystals. Hope it helps !:)

Answer:- Liliana can raise 35 zombie soldiers with 10 power crystals.


Explanation:-

Let the number of zombie soldiers raised by 10 dark power crystals be 'x'.

Zombie raised by 4 power crystals = 14

Since the number of zombie and power crystals are in direct proportion.

Therefore, we get

[tex]\frac{x}{10}=\frac{14}{4}[/tex]

Multiply 10 on both the sides, we get

[tex]\Rightarrow\ x=\frac{14}{4}\times10=35[/tex]

Liliana can raise 35 zombie soldiers with 10 power crystals.

If the correlation between height and weight of a large group of people is 0.75​, find the coefficient of determination​ (as a​ percent) and explain what it means. assume that height is the predictor and weight is the​ response, and assume that the association between height and weight is linear.

Answers

Independent variable is the predictor variable which is the height and dependent variable is the response variable which is weight in this scenario.

The square of correlation coefficient gives the coefficient of determination. It is denoted by R² (R squared).

We are given:
R = 0.75

So,
R²  = 0.75²

R² = 0.5625

R²  = 56.25 %
The coefficient of determination tells how much of the trend of dependent data can be explained by the independent data using the linear regression model. So in the given case, Height can explain 56.25% of the trend in the weight.

Answer:

Step-by-step explanation:

Given that  the correlation between height and weight of a large group of people is 0.75

Coefficient of determination = [tex]R^2 =0.75^2 =0.5625=56.25%[/tex]

Coefficient of determination gives us the strength of association between two variables and how much the variability of the response variable i.e. weight is due to the variability of the predictor variable i.e. height

When there is a linear association correlation coefficient square gives us the reason for the variability and percentage due to the variability in predictor variable
