The breaking strengths of cables produced by a certain manufacturer have a mean, u, of 1750 pounds, and a standard deviation of
AlladinOne [14]

Answer:

We accept the null hypothesis that the  breaking strength mean is less and equal to 1750 pounds and has not increased.

Step-by-step explanation:

The null and alternative hypotheses are stated as

H0:  u ≥ 1750   i.e the mean is less and equal to 1750

against the claim

Ha: u > 1750  ( one tailed test)  the mean is greater than 1750

Sample mean = x`= 1754

Population mean = u = 1750

Population deviation= σ = 65 pounds

Sample size= n = 100

Applying the Z test

z= x`- u / σ/ √n

z= 1754- 1750 / 65/ √100

z= 4/6.5

z= 0.6154

The significance level alpha = 0.1

The z - value at 0.1 for one tailed test is ± 1.28

The critical value is z > z∝.

so

0.6154 is < 1.28

We accept the null hypothesis that the  breaking strength mean is less and equal to 1750 pounds and has not increased.

1.) Is y= cosx/x an even, odd , or neither <br><br> 2.) Is y=sinx/x and even, odd , or neither
Marrrta [24]

Answer:

Step-by-step explanation:

1) y = (cos x) / x is neither, since cos x is even and x is odd.  Expressions such as this are neither even nor odd. /

2) y = (sin x) / x is even, since sin x and x would either both be positive at the same time or negative at the same time.  Recall that (-) / (-) is positive, just as (+) / (+) is positive.

<h3>✽ - - - - - - - - - - - - - - -  ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ✽</h3>

➷ Work out the time for Cardiff to Swansea:

time = distance/speed

Substitute in the values:

time = 69/60

Solve:

time = 1.15 hours = 69 minutes

Add together the total time and distance:

72 + 69 = 141

48 + 69 = 117

speed = distance/time

speed = 141/1.95

speed = 72.3 km/h

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^
