What is the value of X
zhannawk [14.2K]

Answer:

27=x

Step-by-step explanation:

We can use the triangle angle bisector theorem

x+8            2x-5

--------- = ------------

10                14

Using cross products

14(x+8) = 10 (2x-5)

Distribute

14x +112 = 20x -50

Subtract 14x from each side

14x-14x +112 = 20x-14x -50

112 = 6x-50

Add 50 to each side

112+50 = 6x-50+50

162 = 6x

Divide by 6

162/6 = 6x/6

27=x

Alma is estimating the proportion of students in her school district who, in the past month, read at least 1 book. From a random
Maurinko [17]

Answer:

D)

(0.64 +1.645 \sqrt{\frac{0.64(0.36)}{50} })

90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month

(0.52846 , 0.75166)

Step-by-step explanation:

<u><em>Step:-1</em></u>

Given that the random sample size 'n' = 50

The sample proportion

                       p^{-} = \frac{32}{50} = 0.64

90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month

(p^{-} - Z_{0.90} \sqrt{\frac{p(1-p)}{n},  } , p^{-} +Z_{0.90} \sqrt{\frac{p(1-p)}{n} })

<u><em>Step(ii):-</em></u>

Level of significance = 0.90

Z₀.₉₀ = 1.645

(0.64 - 1.645 \sqrt{\frac{0.64(1-0.64)}{50},  } , 0.64 +1.645 \sqrt{\frac{0.64(1-0.64)}{50} })

(0.64 - 1.645 \sqrt{\frac{0.64(0.36)}{50},  } , 0.64 +1.645 \sqrt{\frac{0.64(0.36)}{50} })

(0.64 -1.645(0.06788) , (0.64 + 1.645(0.06788)

(0.52846 , 0.75166)

<u><em>Final answer:-</em></u>

90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month

(0.52846 , 0.75166)

What can you say about the end behavior of the function f(x)=-4^6+6x^2-52 ????
frosja888 [35]
Letter C is correct.
When the function is even, (all powers are even) both ends will go in the same direction.
In this case since the leading coefficient is negative, both ends will go down.

Rico earns a weekly salary of $750 and a 5% total Commission on his sales Sean earns a weekly salary of $1,100 and a 2.5% commis
NNADVOKAT [17]
To answer this item, we let x be the amount of sales for each of them. Their weekly earnings would be as follows,

Rico:
       750 + 0.05x


Sean: 
      1100 + 0.025x

 Equating both expressions,

     750 + 0.05x = 1100 + 0.025x

Simplifying,
      0.025x = 350

The value of x from the equation is 14000.

Answer: $14,000.
