In your question which ask for the how its possible for the two triangles to intersect in one, two, three, four, five, six points but not seven points. Its because the triangles has only 3 sides which means that the intersection that could from in the two is less than 7 or maximum of 6

To determine the effect of 100% nitrate on the growth of pea plants, several specimens were planted and then watered with 100% n

Bond [772]

Answer:

Step-by-step explanation:

From the attached photo

mean = 15.76

Standard deviation = 1.66

c) We want to determine a 90% confidence interval for the mean growth of pea plants

For a confidence level of 90%, the corresponding z value is 1.645. This is determined from the normal distribution table.

We will apply the formula

Confidence interval

= mean ± z ×standard deviation/√n

It becomes

15.76 ± 1.645 × 1.66/√7

= 15.76 ± 1.645 × 0.63

= 15.76 ± 1.04

The lower end of the confidence interval is 15.76 - 1.04 =14.72

The upper end of the confidence interval is 15.76 + 1.04 =16.8

Answer:

Actual distance between two city = 40 miles

Step-by-step explanation:

Given sample size;

1 inch = 10 miles

Distance between two city = 4 inch

Find:

Actual distance between two city

Computation:

Actual distance between two city = Sample size of 1 inch in miles x Distance between two city

Actual distance between two city = 4 x 10

Actual distance between two city = 40 miles

I know that: the first term of the sequence is -2, and the fifth term is - 1/8 . What is the 2nd term, 3rd term 4th term do you

Murljashka [212]

Solution

Here the first term = -2

5th term = -1/8

Now we have to find the common ratio (r)

Fifth term A5 = -1/8

-1/8 = $a_{1} r^{4}$

Here $a_{1} = -2$

Plug in $a_{1} = -2$ in the fifth term and find the value of r.

-1/8 = -2 $r^{4}$

$r^{4} = \frac{-1/8}{-2}$

$r^{4} = \frac{1}{16}$

Taking 4th root, we get

r = $\frac{1}{2}$

Now let's find the second term.

$a_{2} =$ first term *r = -2 *1/2 = -1

2nd term = -1

3rd term = second term * 1/2 = -1 * 1/2 = -1/2

4th term = 3rd term *r = -1/2 *1/2 = -1/4

Thank you :)
