2y + 4 + x = 90

2y + 4 + 3y + x = 180

5y + x + 4 = 180

x = 176 - 5y

2y + 4 + (176 - 5y) = 90

-3y + 180 = 90

-3y = -90

y = 30

x = 176 - 5(30)

x = 26 degrees

Hope this helps! :)

the initial cost to set up a website is $48. it cost $44 per month to maintain the website . how many months will you be able to
Delicious77 [7]

We would start with 400 - 48, to cover the initial cost. We would be left with 352 dollars to spare for the monthly bill. 352 divided by 44, which is the monthly cost, would be 8. The website could be set up and held for 8 or 9 months, depending on if the initial cost is paid at the same time or before the first monthly one.

Evaluate x1 - x-1 + x0 for x = 2.
Gnoma [55]
Hi! For this problem, you must replace the letter “X” with the number 2. Your equation will then be (2*1)- (2-1)+ (2*0). This will then simplify to: 2 - 1 + 0. Therefore, your final answer will be:

olga_2 [115]

Answer:

-x+20=31

Step 1: Subtract 20 from both sides.

−x+20−20=31−20

−x=11

Step 2: Divide both sides by -1.

−x

−1

=

11

−1

x=−11

The blood platelet counts of a group of women have a​ bell-shaped distribution with a mean of 247.9 and a standard deviation of
labwork [276]

Answer:

A) Approximate percentage of women with platelet counts within 2 standard deviations of the​ mean, or between 118.5 and 377.3 = 95%

B) approximate percentage of women with platelet counts between 53.8 and 442.0 = 99.7%

Step-by-step explanation:

We are given;

mean;μ = 247.9

standard deviation;σ = 64.7

A) We want to find the approximate percentage of women with platelet counts within 2 standard deviations of the​ mean, or between 118.5 and 377.3.

Now, from the image attached, we can see that from the empirical curve, the probability of 1 standard deviation from the mean is (34% + 34%) = 68 %.

While probability of 2 standard deviations from the mean is (13.5% + 34% + 34% + 13.5%) = 95%

Thus, approximate percentage of women with platelet counts within 2 standard deviations of the​ mean, or between 118.5 and 377.3 = 95%

B) Now, we want to find the approximate percentage of women with platelet counts between 53.8 and 442.0.

53.8 and 442.0 represents 3 standard deviations from the mean.

Let's confirm that.

Since mean;μ = 247.9

standard deviation;σ = 64.7 ;

μ = 247.9

σ = 64.7

μ + 3σ = 247.9 + 3(64.7) = 442

Also;

μ - 3σ = 247.9 - 3(64.7) = 53.8

Again from the empirical curve attached, we cans that at 3 standard deviations from the mean, we have a percentage probability of;

(2.35% + 13.5% + 34% + 34% + 13.5% + 2.35%) = 99.7%
