Answer:

integer  3 represents elevator final position with respect to the main floor.

Step-by-step explanation:

Given  : An elevator starts at the main floor and goes up 8 floors. It then goes back down 5 floors.

To find : What integer represents elevator final position with respect to the main floor.

Solution : We have given

Elevator starts at the main floor and goes up floors = + 8 ( for up).

Then goes back down floor  =  - 5  ( - sign for down).

Final position  :  8 - 5 = 3 .

It will reach at 3 floor from the main floor .

Therefore, integer  3 represents elevator final position with respect to the main floor.

What does the E in an electrode code stands for?​
dalvyx [7]

Answer:

The “E” indicates an arc welding electrode. The first two digits of a 4-digit number and the first three digits of a 5-digit number stand for tensile strength.  So, “1” stands for an all position electrode, “2” for a flat and horizontal electrode, and “4” for a flat, horizontal, vertical down and overhead electrode

algol13

Answer:

2:3:5

Step-by-step explanation:

Here, we are going to be using direct numbers from the ratio

Circles to triangles is; 2:3

So for 200 circles, there are 300 triangles

Triangles to rectangles ; 2:5

300 triangles, there are 500 rectangles

Circles to triangles to rectangles is thus;

200: 300:500

= 2:3:5

Eagle Outfitters is a chain of stores specializing in outdoor apparel and camping gear. They are considering a promotion that in
Zina [86]

Answer:

Step-by-step explanation:

Assuming that:

the promotion will be considered to be a  success if more than 10% use the coupons received.

and coupons are sent to 100 credit card customers.

Then, the null hypothesis and alternative hypothesis is:

\mathbf{H_o:p\le 0.10} \\ \\ \mathbf{H_a:p> 0.10}

sample size n = 100

Using the eagle file data;

the no of people in the sample who use the coupon = 13

then,

\hat p = \dfrac{x}{n}

\hat p = \dfrac{13}{100}

\hat p = 0.13

Test statistics can be computed as:

Z = \dfrac{\hat p - p }{\sqrt{\dfrac{p(1-p)}{n}}}

Z = \dfrac{0.13 - 0.10 }{\sqrt{\dfrac{0.10(1-0.10)}{100}}}

Z = \dfrac{0.03 }{\sqrt{\dfrac{0.09}{100}}}

Z = \dfrac{0.03 }{\sqrt{0.0009}}

Z = \dfrac{0.03 }{0.03}

Z = 1

P-value = P(Z > 1) \\ \\ P-value = 1 - P(Z < 1 ) \\ \\ P-value = 1 - 0.8413 \\ \\ P-value = 0.1587 \\ \\

At ∝ = 0.05

Since, P-value is greater than ∝, then we fail to reject \mathbf{H_o}.

Therefore, Eagle should not go with the promotion; a larger sample should be taken.
