Answer:
No Solution.
Step-by-step explanation:
-1/2x + y = 4
y = 1/2x + 6 Transposing:
- 1/2 x + y = 6
Comparing the first and third equations we see that left sides are the same and right sides are different, so there is NO Solution.
what is left if you deduct 1/7 from 3/4
Answer:
17/28
Step-by-step explanation:
deduct 1/7 from 3/4
i.e.,
3/4 - 1/7
3 × 7 - 1 × 4/7 × 4
21 - 4/28 = 17/28
Thus, if you deduct 1/7 from 3/4 then 17/28 is left

le Gianna just started a running plan where she runs 20 miles the first week and then increases the number of miles she runs by 5% each week. If she keeps up this plan for 17 weeks, how many total miles would Gianna have run, to the nearest whole number?
Answer:
Gianna ran 40 miles over the course of 17 weeks.
Step-by-step explanation:
20 miles in the first week.
5% increase each week.
17 weeks.
5% * 20 = 11 mile increase each week.
17 * 1 = 1717 mile increase over the course of 17 weeks.
20 + 17 = 3737 miles over the course of 17 weeks.
Round 37 to the nearest whole number.
37 ^ 40The number of total miles that would Gianna have run, to the nearest whole number should be considered as the 40.
Calculation of the number of miles:
Since
20 miles in the first week.
5% increase each week.
And, then there is 17 weeks
So, if 5% of 20 = 1
So here the total miles be like
= 20 + 17
= 37
= 40
hence, The number of total miles that would Gianna have run, to the nearest whole number should be considered as the 40.

A scuba diver has a rope connecting the dive boat to an anchor on the ocean floor. The rope is 13ft long. The water is 5ft deep. How far is the anchor from a point directly below the boat?
Answer:
The anchor is 12 feet far from the point directly below the boat.
Step-by-step explanation:
Given that:
Length of rope connecting the dive boat to an anchor = 13 feet
Depth of water = 5 feet
Here,
The rope connecting the dive boat to the anchor will serve as hypotenuse of a right angle triangle, depth of water will be the height of triangle and distance from anchor to point directly below the boat will be base of triangle.
Using Pythagorean theorem;
[tex]a^2+b^2=c^2[/tex]
a = 5 , c = 13
[tex](5)^2+b^2=(13)^2\\25+b^2=169\\b^2=169-25\\b^2=144[/tex]
Taking square root on both sides
[tex]\sqrt{b^2} =\sqrt{144}\\b=12[/tex]
Hence,
The anchor is 12 feet far from the point directly below the boat.

Answer: full of wonders.
Step-by-step explanation: personally I think this is the answer but I’m not sure. I thought this was correct because George later on in the text is in awe of how the invention made him look at the horses in the photos in a completely different way then he sees them when they’re outside his window. Since he is in awe I think that full of wonders is connected with that fact but again this is just my opinion. Hope you do well :)

Find 3 consecutive numbers who sum is 216
Answer:
the three consecutive numbers be 71, 72 and 73 respectively
Step-by-step explanation:
The computation of the 3 consecutive numbers is shown below:
Let us assume the three consecutive numbers be x , x+1 and x + 2
Now their sum is
x + x + 1 + x+ 2 = 216
3x + 3 = 216
3x = 216 -3
3 = 213
x = 71
x + 1 = 71 + 1 = 72
x + 2 = 71 + 2 = 73
Hence, the three consecutive numbers be 71, 72 and 73 respectively

Instead of building the enclosure of maximum area, the company wishes to build only a 20,000 square foot enclosure still using up all the fencing and situated with one side on the river. Find the dimensions of the enclosure that will satisfy these requirements by doing the following: 14. What equation can be solved to find the possible widths
Answer:
x = 80000/L f
Step-by-step explanation:
When using only three sides for fencing a rectangular area, sides will be
"x " and "y " x = 2*y x is the largest side of the rectangular area
we only fence one y side ( the other side is a river
So the perimeter is L = x + 2*y or L = 4*y
On the other hand if now the area will be 20000 f²
A = x*y = 20000 ⇒ y = 20000/ x
As the fence material is the same as that of the maximum area
L = 4*y L = 4* 20000 / x
L*x = 80000
Then x = 80000/L
Where L is the quantity of fencing material

Environmental engineers are using data collected by weather data centers to learn how climate affects the sea ice. Of ice melt ponds studied in a certain region, were classified as having "first-year ice". The researchers estimated that about % of melt ponds in the region have first-year ice. Estimate, with 90% confidence, the percentage of all ice-melt ponds in the region that have first-year ice. Give a practical interpretation of the results.
Complete Question
Environmental engineers are using data collected by weather data centers to learn how climate affects the sea ice. Of 526 ice melt ponds studied in a certain region, 84 were classified as having "first-year ice". The researchers estimated that about 16% of melt ponds in the region have first-year ice. Estimate, with 90% confidence, the percentage of all ice-melt ponds in the region that have first-year ice. Give a practical interpretation of the results.
Answer:
The 90% confidence interval is [tex] 0.1337 < p < 0.1857 [/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 526
The number that were classified to having a 'first-year ice ' is k = 84
The population proportion is p = 0.16
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{k}{ n }[/tex]
=> [tex]\^ p = \frac{ 84}{ 526 }[/tex]
=> [tex]\^ p = 0.1597[/tex]
From the question we are told the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 90 ) \%[/tex]
=> [tex]\alpha = 0.10[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.645[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{ p (1- p)}{n} } [/tex]
=> [tex]E = 1.645 * \sqrt{\frac{0.16 (1- 0.16)}{ 526} } [/tex]
=> [tex]E = 0.026 [/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\^ p -E < p < \^ p +E[/tex]
=> [tex]0.1597 -0.026 < p < 0.1597 -0.026 [/tex]
=> [tex] 0.1337 < p < 0.1857 [/tex]
A significance test is to be conducted concerning population means and based on the difference between the two sample means . What assumptions are required in order for the two-sample z statistic to be valid
Answer:
In order for the two-sample z statistic to be valid we need that the following assumptions hold:
each sample and population must be independent from each othereach population must be normally distributedthe population standard deviations must be known or the sample sizes must be ≥ 30samples must be randomdata has to be continuousWhat is the value of the expression -x + 3y, if x = 5 and y = -4?

Andrew ran 20 miles last week (at the same pace) and spent a total of 150 minutes running. If he runs for 240 minutes this week, at the same pace as last week, how many miles will he complete?
Answer:
He ran 32 miles in 240 minutes.
Step-by-step explanation:
20 miles in 150 minutes.
20 ÷ 150 = 0.13
The three repeats.
He ran 0.13 (2/15) miles every minute.
0.13 * 240 = 32
He ran 32 miles in 240 minutes.

a polygon on a coordinate grid was transformed using rule (x,y) (x-4,y-3) . which of these describes the transformation
Answer:
A. A translation 4 units to the left and 3 units down.
Step-by-step explanation:
The new coordinate of the triangle will be (-3, -1), (-2, 0), and (-1, -2).
What is a transformation of a point?A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.
A polygon on a coordinate grid was transformed using the rule given below.
(x, y) ⇒ (x - 4, y - 3)
The new coordinate of the coordinate (1, 2) will be
(x, y) ⇒ (1 - 4, 2 - 3)
(x, y) ⇒ (-3, -1)
The new coordinate of the coordinate (2, 3) will be
(x, y) ⇒ (2 - 4, 3 - 3)
(x, y) ⇒ (-2, 0)
The new coordinate of the coordinate (3, 1) will be
(x, y) ⇒ (3 - 4, 1 - 3)
(x, y) ⇒ (-1, -2)
The new coordinate of the triangle will be (-3, -1), (-2, 0), and (-1, -2).
