Answer:
x=4
Step-by-step explanation:
(X-4)(X-4)=0
Using the zero product property
x-4 =0 x-4 =0
x-4+4=0+4 x-4+4 =0+4
x=4 x=4
Answer:
Joan could make 16 batches of cookies because for each batch of cookies she only needs 1 cup of flour. So she would use 1 cup of flour for each batch and since she has 16 cups she would be able to make 16 batches.
Step-by-step explanation:
Answer:
Reject H0; there is significant evidence that the proportion of site users who get their world news on this site has changed since 2013 and is significantly different from 45%
Step-by-step explanation:
Sample size, n = 3603
x = 1697
Phat = x/n = 1697/3603 = 0.4709 =47.09%
H0 : p = 0.45
H1 : p > 0.45
The test statistic :
(phat - p) / sqrt[(p(1 - p)) /n]
(0.4709 - 0.45) / sqrt[(0.45(0.55))/3603]
0.0209 / 0.00828810932
Test statistic = 2.5217
The Pvalue :
Using the Pvalue from Test statistic calculator ; α = 0.05 ;
Pvalue at 95% confidence = 0.005839
Pvalue < α ;
Hence, we reject the Null
Therefore, we conclude that the sample gives evidence that the proportion of site users who get their world news on this site has changed since 2013.
Any expression multiplied by a zero gives a product of zero.
so your expression is :
0+6.27 = 6.27
