John made this model to show \frac{4}{7}\times\frac{13}{9} 7 4 ​ × 9 13 ​ Using John's model, what is \frac{4}{7}\times\frac{13}
harkovskaia [24]

Answer:

\frac{4}{7}\times\frac{13}{9} = \frac{52}{63}

Step-by-step explanation:

Given

See attachment for model

Required

Determine \frac{4}{7}\times\frac{13}{9} from the model

The model is represented by:

\frac{4}{7}\times\frac{13}{9} = \frac{4}{7}\times\frac{9}{9} + \frac{4}{7}\times\frac{4}{9}

To get: \frac{4}{7}\times\frac{9}{9}, we consider the first partition

The number of shaded box is 63 ---- this represents the denominator

The total boxes shaded at the bottom is 36 ---- this represents the numerator

So, we have:

\frac{4}{7}\times\frac{9}{9} = \frac{36}{63}

To get: \frac{4}{7}\times\frac{9}{9}, we consider the first partition

The number of shaded box is 63 ---- this represents the denominator

The total boxes shaded at the bottom is 16 (do not count the gray boxes) ---- this represents the numerator

So, we have:

\frac{4}{7}\times\frac{4}{9} =\frac{16}{63}

The equation becomes:

\frac{4}{7}\times\frac{13}{9} = \frac{4}{7}\times\frac{9}{9} + \frac{4}{7}\times\frac{4}{9}

\frac{4}{7}\times\frac{13}{9} = \frac{36}{63} + \frac{16}{63}

\frac{4}{7}\times\frac{13}{9} = \frac{36+16}{63}

\frac{4}{7}\times\frac{13}{9} = \frac{52}{63}

What is the y-intercept of the function f(x) = –2/9 + 1/5
dolphi86 [110]
The equation has no X variable so whatever that adds up to becomes the y-intercept. 

- 2/9 + 1/5 >> - 10/45 + 9/45 = - 1/45 


Your y-int is - 1/45 or (0, - 1/45)

Can you conclude with a high degree of confidence that the population means for Iowa and New Jersey students are​ different? A.
Katen [24]

Complete Question

The complete question is  shown on the first uploaded image

Answer:

Option A is correct

Step-by-step explanation:

From the question we are told that  

  The  95% confidence interval of the mean  score of all  New Jersey third graders  is  (58.957 ,  63.043)

   The sample size is  n =  184

   The sample average is  \mu = 65 \ points

   The standard deviation is   \sigma  =  13 \ points

    The  90%  confidence interval for the difference in mean score between lowa and New Jersey is  (-6.33 ,  -1.67 )

   The  p-value is  p-value  =  0.0048

Generally given that the p-values is very low compared to the level of significance (100 -90 =  10% = 0.10 )  we can reject the null hypothesis which is usually a  claim that the means of the  population are the same )

Hence the population means are different .
