Answer:

GA=17

Step-by-step explanation:

As A, B, C are the midpoints of the sides of AGHJ,

so GH= 2(CB)

⇒7z-1= 2(4z-3)

⇒7z-1= 8z-6

⇒7z-8z= -6+1

⇒-7= -5

z=5

so GA=CB

⇒GA= 4(5)-3= 17

hope it helps...

have a great day

The value of the variable 'z' is 5. Then the length of GA will be 17 units.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

Use △GHJ, where A, B, and C are midpoints of the sides. When GH = 7z − 1 and CB = 4z − 3.

From the graph, then the condition is given as,

GH = 2 × BC

7z - 1 = 2 × (4z - 3)

Simplify the equation, then we have

7z - 1 = 2 × (4z - 3)

7z - 1 = 8z - 6

6 - 1 = 8z - 7z

z = 5

Then the length of the GA is given as,

GA = BC

GA = 4z - 3

GA = 4 (5) - 3

GA = 20 - 3

GA = 17 units

The value of the variable 'z' is 5. Then the length of GA will be 17 units.

Answer:

If your saying estimate this number in a decimal without calculators I think I might be able to help as illustrated below:

Step-by-step explanation:

2 5/6 shows that the whole number will be a 2. The 5/6 is a decimal below one as it is not one whole fraction. This means that we have to estimate the value of 5/6 and add that value to the number 2. 1/3 is a common fraction that is equal to about 0.33. This is because 0.33 + 0.33 + 0.33 is almost 1, which means 1/3 of one is indeed equal to 0.33.

This means we divide 0.33 by 2, because that would be equal to (1/3)/(2), or 1/6. 0.33/2 seems like it would be 16.5. 16.5 * 5, as in 5/6, would be 82.5.

I would then say that the estimate of 2 5/6 is 2.83.

Answer:

The critical numer is x = -3/10

Step-by-step explanation:

We need to find the derivative of the function and then equal to zero to get the values of x.

The function is:

[tex]f(x)=10x^{2}+6x[/tex]

Let's take the derivative whit respect of x and equal to zero.

[tex]f'(x)=20x+6[/tex]

[tex]0=20x+6[/tex]

Now, we just need to solve it for x.

[tex]x=-\frac{3}{10}[/tex]

The critical numer is x = -3/10

Answer:

a) [tex]\pi(0)=\frac{1}{3}[/tex]

b) [tex]X=\frac{2}{3}[/tex]

Step-by-step explanation:

From the question we are told that:

Arrival time with Poisson's process =[tex]t_p=2-3minutes[/tex]

where

[tex]\lambda_1=2\\\lambda_2=3[/tex]

a)

Generally the equation Poisson's process is mathematically given by

[tex]\pi()n*\lambda_1=\pi(n+1*) \lambda_2[/tex]

[tex]\pi()n*2=\pi(n+1*)*3[/tex]

[tex]\pi(n+1)=\frac{2}{3} \pi+1*\pi(0)[/tex]

Therefore

[tex]\pi(0)(1+2/3+(2/3)^2+...)=1[/tex]

[tex]\pi(0)=\frac{1}{3}[/tex]

Answer:

a) yes

b) ( 0.0280 , 0.1720 )

c) No

Step-by-step explanation:

A) Determine if the sample sizes are large enough

where :

ages between ( 18 to 29 )

p1 = 0.48 ,

n1 = 178 ,      ∴ n1 P1 = 85.44  also n1 ( 1 - p1 ) = 92.56

ages between ( 50 to 64 )

P2 = 0.03 ,

n2 = 427     ∴ n2p2 = 12.81     also n2( 1 -p2 ) = 414.19

since all the values ae above 10 we can conclude that the sample sizes are large enough

answer = yes

Answer:

78°

Step-by-step explanation:

In this problem, we need to find the value of angle 2.

Angle 2 is an Alternate exterior angle. Alternate exterior angles are formed by a transversal intersecting two parallel lines. They are located outside the two parallel lines.

To form an alternate exterior angle, angle 2 must be equal to 78°. Hence, we can say that the value of ∠2 is equal to 78°.

Answer:

  A: 8x +24

  B: not equivalent for any value of x

Step-by-step explanation:

Part A:

The factor of 4 on the outside of parentheses multiplies each term inside:

  M = 4(2x) +4(6)

  M = 8x +24 . . . . . expression equivalent to M

__

Part B:

Expressions M and N are not equivalent for any value of x. They are equivalent if their difference is zero or can be made to be zero. Subtracting N from M, we find the difference to be ...

  M -N = (8x +24) -(8x +10) = 14

There is no value of x that will make the difference of 14 become zero.

Answer:

0.5793 = 57.93% probability that the household uses 480 gallons of water or less per month

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 470 gallons and standard deviation of 50 gallons.

This means that [tex]\mu = 470, \sigma = 50[/tex]

What is the probability that the household uses 480 gallons of water or less per month?

This is the pvalue of Z when X = 480. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{480 - 470}{50}[/tex]

[tex]Z = 0.2[/tex]

[tex]Z = 0.2[/tex] has a pvalue of 0.5793

0.5793 = 57.93% probability that the household uses 480 gallons of water or less per month

Answer:

It is 10 because 5 times 10 is 50

Answer:

A) = 5

B) = 10

C) = (5 x 10)= 50

Step-by-step explanation:

Area of a rectangle a x b = c

Where a is the short side

Where b is the long side

And c is our area

Okay now we we have to think what numbers give us 50 so ( 1 x 50 , 5 x 10 , 2 x 25)

So since now we have the numbers we look for a number that is twice the other and is - 5 the other one and the only numbers are 10 and 5 so in conclusion

A= 5

B= 10

C= 50
