First, you must find the width of GHJK. Since the area of it is 84m², divide 84 by 7.
84÷7=12
So the width of GHJK is 12m.
Next, find the scale of GHJK to LMNP. Since the height of both are already available, you can divide 21÷7 to get 3
This means that to get the width of LMNP you must multiply the width of GHJK by 3.
12×3=36.
Now, to get the area of LMNP, multiply 21 by 36.

21×36=756

So, the area of LMNP is 756m². (Don't forget the units!>

fiasKO [112]
To answer the given question, substitute the values given to the equation,
                                     S = π x sqrt(r² + h²)
 
                                   155 m = π x sqrt (r² + (21 m)²))
 
                                        r = 44.65 m
Therefore, the radius of the cone is approximately 44.65 m.

Calculate the volume of the regular triangular pyramid
snow_lady [41]

Answer:

70.83 ft³

Step-by-step explanation:

The volume of a pyramid is:

\frac{bh}{3}, where b is the base area and h is the height.

Let's first find the area of the base.

17\cdot5=85\\85\div2=42.5

Multiplying this by 5:

42.5\cdot5=212.5

Dividing by 3:

212.5\div3=70.83.

Hope this helped!

6. A hypothesis test in which rejection of the null hypothesis occurs for values of the point estimator in either tail of the sa
natita [175]

Answer:

A two-tailed test.

Step-by-step explanation:

ANOVA is a short term or an acronym for analysis of variance which was developed by the notable statistician Ronald Fisher. The analysis of variance (ANOVA) is typically a collection of statistical models with their respective estimation procedures used for the analysis of the difference between the group of means found in a sample. Simply stated, ANOVA helps to ensure we have a balanced data by splitting the observed variability of a data set into random and systematic factors.

In Statistics, the random factors doesn't have any significant impact on the data set but the systematic factors does have an influence.

Basically, the analysis of variance (ANOVA) procedure is typically used as a statistical tool to determine whether or not the mean of two or more populations are equal through the use of null hypothesis or a F-test.

Hence, the null hypothesis for an analysis of variance (ANOVA) requires that all treatments or samples should be generated from populations having the same mean.

A hypothesis test in which rejection of the null hypothesis occurs for values of the point estimator in either tail of the sampling distribution is called a two-tailed test.

Written as a simplified polynomial in standard form, what is the result when
Naddika [18.5K]

Step-by-step explanation:

7x+10 - (x+2)^2

7x+10 - (x^2 + 2x + 4)

7x+ 10 - x^2 - 2x - 4

5x + 6 - x^2

then if u have to find the value of x then put the value of a = 1,b = 5,c = 6 in quadratic formula (-b + under root b^2 - 4ac / 2a) or (- b - under root b^2 - 4ac / 2a) it will gives the value of x...

HOPE it u..!!

edit - do let me knw that it's right or not..!!
