*PLS HELP*The Question Is In The Attachment​

Mathematics
1 answer:
malfutka [58]2 years ago
5 0

Answer:

Step-by-step explanation:

Rhombus:

Base = b = 14 in

altitude = h = 12 in

Area of rhombus = b*h = 14 * 12 = 168 in²

Triangle:

base = b = 12 in

Height = h = 14 in

Area \ of \ triangle = \dfrac{1}{2}bh=\dfrac{1}{2}*12*14=12*7=84 \ in^{2}

Area of the figure = area of the rhombus + area of the triangle

                               = 168 + 84

                               = 252 in²

This is a standard deviation contest. You must choose four numbers from the whole numbers 0 to 10 , with repeats allowed. (a) Ch
irina [24]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following instructions :

Choose 4 numbers from the whole numbers 0 - 10

Note : Repetition is allowed

Choose 4 numbers with the smallest possible standard deviation.

The smallest possible value of standard deviation obtainable is 0;

Hence in other to obtain a standard deviation value of 0, then;

The mean squared deviation value must be zero (0)

Σ(X - mean)^2 = 0

To achieve this, the values of X and the mean must be the same.

Hence all 4 numbers (X) must be the same in other to have a mean value which is equal to X

For instance :

If X = 3, 3, 3, 3 (since Repetition is allowed)

Man value = (3+ 3+ 3+ 3) / 4 = 12 / 4 = 3

Σ(3 - 3)² = 0 for all values of x

√Σ(x - mean)² / n = 0 ; if all values of x are the Same

n = Number of observations

A possible list of values is (3,3,3,3)

What is the answer X/7-3>8
mamaluj [8]

Answer:

x > 77

Step-by-step explanation:

According to order of operations rules, we must carry out division before addition or subtraction.  In this case we wish to isolate x and are permitted to simplify the inequality by combining the "like terms" 3 and 8, as follows:

X/7-3>8

     +3 +3

--------------

x/7 > 11

The easiest way in which to solve for x is to multiply both sides of this inequality by 7:

7(x/7) > 7(11), or

x > 77

All numbers greater than 77 are part of the solution set.

The G.CD of the number is 17 and the L.C.M is 140,If one of the number is 20, Find the other number​
Alik [6]

Answer:

HCF Of two nos. is 17

Let another no. be x

we know that HCF ×LCM = Product of two numbers

17×140=20×(x)

20x=2380

x =2380/20

x=119

The other no. is 119

A warje population as a bell shaped distribution with a mean of 200 and a standard deviation of 40 which 1 of the following meas
Shalnov [3]

Answer:

300

(second answer choice)

Step-by-step explanation:

Recall that the Z-distribution is defined as :

Z=\frac{X-\mu}{\sigma}

and therefore, to obtain a Z = 2.5 when the mean value \mu =200, and the standard deviation \sigma = 40 , we solve for "X":

Z=\frac{X-\mu}{\sigma} \\2.5=\frac{X-200}{40}\\40*2.5 =X-200 \\100 = X-200\\X=300
