(Geometry) PART A Find the value of X.

guapka [62]

Answer:

Part A: The answer is B.

As vertically opposite angles are equal

x+10=4x-35

10=3x-35

45=3x

x=15

Part B: The answer is D.

We'll substitute in the value of X in one equation.

x+10

=15+10

=25

As the two angles are equal bot must be 25 degrees.

A statistics professor drew a random sample of 81 observations and found that x with bar on top equals 62 s equals 15. Estimate

ratelena [41]

Answer:

LCL = 59.26 to two decimal places

Step-by-step explanation:

Here, we want to estimate the LCL of the population mean with 90% confidence

We proceed as follows;

Given alpha = 0.1, then Z(0.05)=1.645 (from standard normal table), s = 15

Mathematically;

LCL =x_bar -Z*s/√( n)= 62 - (1.645 * 15)/√81

LCL = 62- (24.675)/9 = 59.2583

LCL = 59.26 to two decimal places

Evaluate t-u/v when t=2 u=(-8) v(-1/2)

Dovator [93]

Simple, plug n chug...

$t- \frac{u}{v}$

t=2

u=-8

v=-0.5

Now, plug in what you have,

$2- \frac{-8}{-0.5}$

$\frac{-8}{-0.5} =16$

Now,

2-16=-14

Thus, your answer, -14.
