This is the concept of application of geometry; the distance that the ladder should be placed will be given by Pythagorean theorem.
thus;
c^2=a^2+b^2
where, c=hypotenuse, a and b are the legs
hence;
15^2+12^2+b^2
b^2=15^2-12^2
b^2=225-144
b^2=81
getting the square root of both sides;
b=sqrt81
b=9
therefore the ladder should be placed 9 feet from the wall for it to reach 12 feet up the building
Answer:
El total de líquido utilizado es . Se echa de litro más de leche que de jugo
Step-by-step explanation:
Para saber la cantidad total de líquido, basta con sumar las cantidades de leche y de jugo de naranja. Vamos a asumir que usa 1/3 de litro de jugo de naranja.
En este caso el total de líquido es 1/2 litro + 1/3 litro. Dado que estas fracciones tienen distinta denominador, debemos sumarlas de la siguiente manera
Para calcular la cantidad extra de leche de más que la cantidad de jugo, restamos estos números. Es decir
Es decir, que echamos de litro más de leche que de jugo.
Answer:
Yes,there is a significant association shell weight and the widths of the opercula
Step-by-step explanation:
Using a correlation Coefficient calculator :
Given the data above :
The Coefficient of correlation(r) obtained is :
0.7632
Obtaining the test statistic :
T = r² / √(1 - r²) / (n - 2)
T = 0.7632² / √(1 - 0.7632²) / (10 - 2)
T = 0.58247424 / 0.2284528
Test statistic = 2.550
The Pvalue from r score , N = 10
Pvalue(0.7632, 10) = 0.01022
α = 0.05
If Pvalue < α ; reject H0
Pvalue < α ; We conclude that there is a significant association shell weights and the widths of the opercula
Hi, I am very happy to help you! I know how to do this! Super Easy!!!!
You will have 2 different x's and they are 3 and 6.
You will have 2 different y's and they are 16 and 19.
In order to get m, you have to subtract y2-y1/x2-x1=m
So the answer would be 1.
In order to solve b, you have to choose one of your given coordinate points and plug them in for x and y and plug in your m, which is 1.
I will be choosing the coordinate points (3,16)
So our b is 13.
So our answer using the form is y=1x+13
Answer:
B is the answer
