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
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
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:

sample size n = 100
Using the eagle file data;
the no of people in the sample who use the coupon = 13
then,



Test statistics can be computed as:






At ∝ = 0.05
Since, P-value is greater than ∝, then we fail to reject
.
Therefore, Eagle should not go with the promotion; a larger sample should be taken.
