Answer:

44 millimeters

Step-by-step explanation:

Because 99 meters divided by 9 = 11.

So, I multiplied 4 x 11 to get 44 millimeters.

Answer:

44 millimeters

Step-by-step explanation:

The ratio is set up as millimeters : meters

On the map, 4 millimeters : 9 meters

The actual length ratio is represented as x millimeters : 99 meters

Since we know its proportional, we can set up the equation:

4/9 = x/99

Solve:

4/9 = x/99

4 * 99 = 9x

396 = 9x

x = 44 millimeters

Another Way

Since we already know it is proportional, 99 = 9 x 11

So we can multiply 4 x 11 to get 44 millimeters.

Describe how to draw a line that passes through the origin and has a slope of -2/-3?

Sophie [7]

First of all you know it wiill be a positive slope as both the rise and the run are negative. a negative divided by a negative equals a positive. so you can plot the points (2,3) and (-2,-3) as they will be points on this line. next you take a straight line and place it so that both points are intercepted. then extend the line outwards.

Part A: Virginia earned $14 walking her neighbors' dogs on Saturday. She earned some extra money on Sunday doing the same thing.

shutvik [7]

Part A: 14 + 14 = y or 14•2 = y
Part B: (n•2) - 2 = a

Not 100% sure that this is correct but, hope this helps! :) If you have any questions than ask me.

Complete the square for 5x^2+10x-16. first one to answer gets brainiest

ella [17]

Answer: x= -1 + √(21/5)

Step-by-step explanation:

The given equation can be written as 5x^2+10x-16=0

keep the x terms on one side and constant on another side

5x^2+ 10x = 16.

Now, to make a complete square like (x+a)^2 = x^2+2xa+a^2.

Divide the given equation by 5 on both sides,

The equation now becomes x^2+2x = 16/5.

The middle term is 2xa=2x

By solving for term "a" in above equation, a= 1

The entire equation of complete square should be x^2+2x+1, which is equal to (x+1)^2

Here, in the equation given in question, +1 is missing to make a complete square.

In order to add 1 we have to simultaneously minus 1 to keep the values in the equation unchanged.

Thus, x^2+2x+1-1 =16/5.

Again moving the constant -1 to other side, we have

x^2+2x+1 =16/5+1

After simplification,

(x+1)^2= 21/5

Taking square root on both sides,

(x+1)= + √(21/5)

The answer is x= -1 + √(21/5)

Researchers examined the bill color (in hue degree) of male and female zebra finches. Here are the summary statistics from the s

sesenic [268]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

In the question some iformation is missing, which can be defined as follows:

Given:

The value of males:

$n_1= 59\\s_1= 1.46\\\bar y_1=2.91\\$

The value of Females:

$n_2=60\\s_2= 2.48\\\bar y_2=7.42\\$

Calculating Degrees of Freedom:

$\bold{ df=\frac{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}{ \frac{1}{n_1-1} (\frac{s_1^2}{n_1})^2+\frac{1}{n_2-1} (\frac{s_2^2}{n_2})^2}}\\\\\\$

$=\frac{(\frac{1.46^2}{59}+\frac{2,48^2}{60})^2}{ \frac{1}{59-1} (\frac{1.46^2}{59})^2+\frac{1}{60-1} (\frac{2.48^2}{60})^2}\\$

$=9.58 or 95$

$\alpha= 1-0.95\\\\$

$= 0.05$

for 95% confidence interval are:

$\frac{\alpha}{2} = \frac{0.05}{2} = 0.025$

From its t-distribution table , the value of t has an region of ( $\frac{\alpha}{2} \ \ 0.025$ ) for (df=95) in its upper tail.

shall be given by = t {0.025}=1.985

Calculating the margin of Error:

$M_OE =t_{0.025} \times \sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}$

$=1.985\times \sqrt{\frac{1.46^2}{59}+\frac{2.48^2}{60}}\\\\=0.739$

The difference in mean bill color " $\mu_2 -\mu_1$ " with 95% confidence intervals:

$\to (7.42 - 2.91) \pm 0.739\\\\\to 4.51 \pm 0.739$

Lower limit=3.771

Upper limit = 5.249
