Answer:
Yes, it would be statistically significant
Step-by-step explanation:
The information given are;
The percentage of jawbreakers it produces that weigh more than 0.4 ounces = 60%
Number of jawbreakers in the sample, n = 800
The mean proportion of jawbreakers that weigh more than 0.4 = 60% = 0.6 = =p
The formula for the standard deviation of a proportion is
Solving for the standard deviation gives;
Given that the mean proportion is 0.6, the expected value of jawbreakers that weigh more than 0.4 in the sample of 800 = 800*0.6 = 480
For statistical significance the difference from the mean = 2× = 2*0.0173 = 0.0346 the equivalent number of Jaw breakers = 800*0.0346 = 27.7
The z-score of 494 jawbreakers is given as follows;
Therefore, the z-score more than 2 × which is significant.
Answer:
The answer is
<h2>15</h2>
Step-by-step explanation:
To find w(- 7) substitute the value of t that's - 7 into w(t) that's for every t in w(t) replace it with - 7
That's
We have the final answer as
<h3>15</h3>

Volume = base area x height
Base area = 6 (1/2 x 3 x 2.6) = 23.4 cm²
Volume = 23.4 x 7 = 164 cm³ (nearest wole number)
Answer: Volume = 164 cm³
Answer:
x=3
Step-by-step explanation:
Let's solve your equation step-by-step.
2(10−13x)+9x=−34x+71
Step 1: Simplify both sides of the equation.
2(10−13x)+9x=−34x+71
Simplify:
−17x+20=−34x+71
Step 2: Add 34x to both sides.
−17x+20+34x=−34x+71+34x
17x+20=71
Step 3: Subtract 20 from both sides.
17x+20−20=71−20
17x=51
Step 4: Divide both sides by 17.
17/17x=51/17
x=3
