Because the confidence interval ▼ ▼ the pooled sample proportion, the significance level, 0, the critical value, there ▼ does not appear to be appears to be a significant difference between the two proportions. Because the confidence interval consists ▼ of values both less than and greater than only of values greater than only of values less than ▼ the critical value, the significance level, the pooled sample proportion, 0, it appears that the first proportion is ▼ less than greater than not significantly different from the second proportion. There is ▼ sufficient insufficient evidence to support the claim that the rate of polio is less for children given the vaccine than it is for children given a placebo.

7, and 7√2

Step-by-step explanation:

The angle ratios are 1.5 : 1.5 : 3, so there are

1.5 + 1.5 + 3 = 6 total parts.  There are 180° in a triangle, so we have

6x = 180

  x = 30

Each part is 30°,

1.5 becomes 45°  (30 plus half of 30)

3 becomes 90°

There are 2 angles with a ratio of 1.5, so we have a 45° - 45° - 90° triangle.  

The side opposite the smallest angle is 7, there are angels with the least measure, so there are 2 sides that are 7.  

The hypotenuse of a 45° - 45° - 90° triangle is larger than the legs by a factor of √2, so the hypotenuse is 7√2
