What is the average (arithmetic mean) of the first 90 measurements in a certain list of 92 measurements? (1) the average of the

marishachu [46]

The sum of all the measurements is just the average times the number.

$\bar x = \frac{1}{n} \sum_{i=1}^n x_i$

$\sum_{i=1}^n x_i = n \bar x$

So if the average of all 92 is 7 the sum of those is $92 \times 7$

The average of the last two is 7.2 so their sum is $2 \times 7.2$

That means the sum of the first 90 is $92 \times 7 - 2 \times 7.2$

so the average of the first 90 is

$\dfrac{92 \times 7 - 2 \times 7.2}{90} = 6.99556$ cm

Rewrite the following equation in slope-intercept form. 14x + 15y = 11 Write your answer using integers, proper fractions, and i

Goshia [24]

Answer:
y = (-14/15) x + (11/15)

Explanation:
The slope-intercept form has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
14x + 15y = 11

To put this in slope-intercept form, we will need to isolate the y as follows:
14x + 15y = 11
15y = -14x + 11
y = (-14/15) x + (11/15)
were:
m is the slope = -14/15
c is the y-intercept = 11/15

Hope this helps :)

how high up on a building will 15 foot ladder reach if the foot of the ladder is placed 5 feet from the building? (be sure to in

mezya [45]

Use the Pythagorean theorem:
$5^2+x^2=15^2 \\
25+x^2=225 \\
x^2=225-25 \\
x^2=200 \\
x=\sqrt{200} \\
x=\sqrt{100 \times 2} \\
x=10\sqrt{2} \\
x \approx 14.14$

The ladder will reach approximately 14.14 feet (exactly 10√2 feet) up on the building.
