Find the value of x in each case:

Mathematics
1 answer:
timurjin [86]3 years ago
7 0

Answer:

angle FGE = 36

angle GEL = 72

and angle GFH = 144

Step-by-step explanation:

well you know that angle GEF = 180 -2x

and that angle GFE = 180 -4x

so all the angles in triangle GEF must add to 180

so you have 180 = 180 -2x + 180 -4x + x

180 = 360 -5x

5x = 180

x = 36

so angle FGE = 36

angle GEL = 72

and angle GFH = 144

Need help... Fast! will give brainiest <br> What is the solution set of x/4 &lt; 9/x ?
Ivenika [448]

Answer:

Option (4)

Step-by-step explanation:

Given inequality is,

\frac{x}{4}\leq \frac{9}{x}

\frac{x}{4}-\frac{9}{x}\leq 0

\frac{x^{2}-36}{4x}\leq 0

x ≥ 0 [For x = 0, fraction is not defined]

(x - 6)(x + 6) ≤ 0

x - 6 ≤ 0

x ≤ 6

Or

x + 6 ≤ 0

x ≤ -6

Therefore, solution set is (-∞, -6] ∪ (0, 6]

By plotting the solution area on a number line,

Option (4) will be the answer.

6.3.6. Among the early attempts to revisit the death postponement theory introduced in Case Study 6.3.2 was an examination of th
kakasveta [241]

Answer:

So the Null hypothesis is rejected in this case

Step-by-step explanation:

  The number of celebrities is  n = 348

   

So to solve this we would assume that p is the percentage of people that died on the month preceding their birth month  

     

  Generally if there is no death postponement then p will be mathematically evaluated as

            p = \frac{1}{12}  

This implies the probability of date in one month out of the 12 months

Now from the question we can deduce that the hypothesis we are going to be testing is  

  Null Hypothesis  \  \  H_0 : p = 0.083

This is a hypothesis is stating that a celebrity  dies in the month preceding their birth

  Alternative \ Hypothesis  H_1 : p < 0.083

   This is a hypothesis is stating that a celebrity does not die in the month preceding their birth

       is c is the represent probability for each celebrity which either c = 0 or c = 1

Where c = 0 is that the probability  that the celebrity does not die on the month preceding his/ her birth month

     and  c =  1  is that the probability  that the  celebrity dies on the month preceding his/ her birth month

  Then it implies that

   for  

       n= 1 + 2 + 3 + .... + 348  celebrities

Then the sum of c for each celebrity would be  c_s = 16

i.e The number of celebrities that died in the month preceding their birth month

We are told that the significance level is  \alpha  = 0.05, the the z value of \alpha is

              z_{\alpha } =  1.65

This is obtained from the z-table

Since this test is carried out on the left side of the area under the normal curve then the critical value will be

                 z_{\alpha } = - 1.65

So what this implies is that  H_o will be rejected if

                z \le -1.65

Here z is the test statistics

Now z is mathematically evaluated as follows

                  z = \frac{c - np}{\sqrt{np_o(1- p_o)} }

                z = \frac{16 - (348 *0.083)}{\sqrt{348*0.083 (1- 0.083)} }

                z =-2.50

From our calculation we see that the value of z is less than -1.65 so the Null hypothesis will be rejected

   Hence this tell us that the  evidence provided is not enough to conclude  that 16 celebrities died a month to their birth month

Look at this square. Find the value of a.
yaroslaw [1]
Perimeter is the total length of all sides. 72 divided by 4 equal sides of a square will give you the value of a. 72 divided by 4 is 18. The value of a is 18 yards.
