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.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
