She should add 48 ounces of of seltzer water because it will allow at least 10 servings. 32 ounces would only be enough to make 8.88 servings

A manufacturer of televisions subjects the equipment to a comprehensive testing process for all essential functions before the t
Vikki [24]

Answer:

The value is   P(X \ge 9) = 0.9138

Step-by-step explanation:

From the question we are told that

  The probability of passing the test is  p =  0.95

  The sample size is  n  =  10  

Generally the distribution of the comprehensive testing of equipment  follows a binomial distribution  

i.e  

         X  \~ \ \ \  B(n , p)

and the probability distribution function for binomial  distribution is  

      P(X = x) =  ^{n}C_x *  p^x *  (1- p)^{n-x}

Here C stands for combination hence we are going to be making use of the combination function in our calculators

  Generally the probability that at least 9 pass the test  is mathematically represented as

    P(X \ge 9) =  P(X = 9 ) + P(X = 10 )

=> P(X \ge 9) =  [^{10}C_9 *  (0.95)^9 *  (1- 0.95)^{10-9}] + [^{10}C_{10} *  (0.95)^{10} *  (1- 0.95)^{10-10}]

=> P(X \ge 9) =  [0.3151] + [0.5987]

=> P(X \ge 9) = 0.9138

Mrs. Benton is making food baskets for the homeless. There are 60 cans of beans and 48 cans of tuna available to be divided equa
tia_tia [17]
54 baskets

the total number of cans available = 60 + 48 = 108

these can be divided by 1 of tuna and 1 of beans

so total of 2

maximum number of baskets then will be
108 / 2 = 54

What sample size is needed to give a margin of error within plus-or-minus 5% in estimating a population proportion with 90% conf
VARVARA [1.3K]

Answer: 271.

Step-by-step explanation:

When the prior population proportion of success is not available, then the formula to find the sample size is given by :-

n=00.25(\dfrac{z_{\alpha/2}}{E})^2

Given : Significance level : \alpha: 1-0.90=0.1

By using the standard normal distribution table ,

Critical value : z_{\alpha/2}=1.645

Margin of error : E=0.05

Then , the required minimum sample size will be :-

n=0.25(\dfrac{(1.645)}{0.05})^2=270.6025\approx271

Hence, the required minimum sample size is 271.

64 is what percent of 40?
ohaa [14]
Think of 40 as 100% (even though it is not)

X will be the value we are looking for

<span> If 40 is 100%, so we can write it down as 40=100%. 
</span>
<span>We know, that x is 64% of the output value, so we can write it down as x=64%
</span>
-----------------------------------------------

1) 40=100%
<span>2) x=64%
</span>----------------------------------------------

<span>40/x=100%/64%
</span>
40/x=100/64
(40/x)*x=(100/64)*x     
40=1.5625*x     -divide both sides of the equation by (1.5625) to get x-
40/1.5625=x 
25.6=x 
x=25.6

So we get;
64% of 40=25.6
