Answer:
x = 8
y = 14
Step-by-step explanation:
2x + 6 = 4x - 10 (Corresponding angles so they're equal)
2x - 4x = -10 - 6
-2x = -16
x = 8
2x + 6 + 13y - 24 = 180 (Supplementary angles so they add up to 180)
2(8) + 6 + 13y - 24 = 180
16 + 6 + 13y - 24 = 180
13y - 2 = 180
13y = 182
y = 14
Answer:
2x+6=4x-10[corresponding angle]
16=2x
x=8
again
2×8+6+13y-24=180°[linear pair]
13y=180+2
y=182/13
y=14

Answer:
C. 7 1/4 units
Step-by-step explanation:
It can be useful to plot the points on a graph.
The two points are on the same horizontal line, so the distance between them is the difference of their x-coordinates.
4 3/4 -(-2 2/4) = (6 +2) +(3/4 +2/4) = 6 5/4 = 7 1/4 . . . . units
__
Some folks find it easier to do the arithmetic by converting to decimal numbers.
4.75 -(-2.50) = 4.75 +2.50 = 7.25 = 7 1/4 . . . . units
The total cost of an electronic photo
display comes to $100. The price
y plus the tax of $6 equals $100.
Write an equation to find the price
of the electronic photo display.
Answers
Answer:
P = y * 1.06
Step-by-step explanation:
Let y be the net price (no tax), t the tax (as a factor) and P the total price (tax included),
P = y * t
From the info provided, we know that for each 100 USD, 6 USD is tax, so 6%,
TIP: By multiplying by 1.06 we add the 6% to the net price (6% is 0.06)
P = y * 1.06

Answers
Answer:
390 Millions of bacteria particles by the end of one week.
Step-by-step explanation:
The Bacteria Growth Rate Formula is: ---> N (T) = N (0) * (1 + R) ^tT
N (0) = # of bacteria present during the beginning of the experiment
Variable R= Growth rate
Variable T= Time taken / elapsed.
Substitute the #'s for N (T)
N (0) and T from the given description
We then get the value of variable R.
220 = 20 * (1+R) ^ (24 hrs)
When solving for R, we get R = 0.105074
1 week= (7 x 24 = 168) hrs
We need to plug in the solutions
Therefore
N (168 hours) = 20 * (1+0.105074) ^168
Which is around 390 millions.
So now we know that there will be 390 millions of bacteria particles at the end of 1 week

three and four-eighths inches
three and five-eighths inches
four and seven-eighths inches
three and seven-eighths inches
Answers
Answer:
three and four-eighths inches
Step-by-step explanation:
Given :
Tick 1 = 2/8 (1 data point)
Tick 2 = 3/8 (3 data points)
Tick 3 = 4/8 (2 data points)
Tick 4 = 5/8 (no points)
Tick 5 = 6/8 (2 data points)
Tick 6 = 7/8 (no data points)
Tick 2 = 3/8 (3 data points)
....
Tick 13 = 1 6/8 (2 data points)
Hence, total length of all meteors that are 1 6/8 inches :
Length of meteor = 1 6/8
Number of meteors = 2
(2 * 1 6/8) = 2 * 14/8 = 28/8 = 3 4/8 = 3 1/2

Hi there!
[tex]\large\boxed{3 \text{ boxes}}[/tex]
Calculate the number of boxes of cubes needed by calculating the volume of the pictured figure.
We can see that it has a width of 4 blocks, depth of 2 blocks, and a height of 8 blocks.
Calculate volume: V = l × w × h
V = 4 × 2 × 8 = 64 cubes in each box.
Since she needs 140 cubes, we can find how many boxes she would need for this amount:
140 ÷ 64 = 2.1875.
However, you cannot buy a part of a box, which is why you must round to a whole number. However, only buying 2 boxes would be too little.
Thus, she would need to buy 3 boxes.

1. Does 30 minutes of aerobic exercise each day provide significant improvement in mental performance? To investigate this issue, a researcher conducted a study with 150 adult subjects who performed aerobic exercise each day for a period of six months. At the end of the study, 200 variables related to the mental performance of the subjects were measured on each subject and the means compared to known means for these variables in the population of all adults. Nine of these variables were significantly better (in the sense of statistical significance) at the ???? = 0.05 level for the group that performed 30 minutes of aerobic exercise each day as compared to the population as a whole, and one variable was significantly better at the ???? = 0.01 level for the group that performed 30 minutes of aerobic exercise each day as compared to the population as a whole. It would be correct to conclude:_____.
a. that these results would have provided very good statistical evidence that 30 minutes of aerobic exercise each day provides some improvement in mental performance if the number of subjects had been larger. It is pre-mature to draw statistical conclusions from studies in which the number of subjects is less than the number of variables measured.
b. that there is very good statistical evidence that 30 minutes of aerobic exercise each day provides some improvement in mental performance.
c. that there is very good statistical evidence that 30 minutes of aerobic exercise each day provides improvement for the variable that was significant at the α = 0.01 level. We should be somewhat cautious about making claims for the variables that were significant at the α = 0.05 level.
d. none of the above.
2. The nicotine content in cigarettes of a certain brand is normally distributed with mean (in milligrams) μμ and standard deviation σ = 0.1. The brand advertises that the mean nicotine content of their cigarettes is 1.5, but you believe that the mean nicotine content is actually higher than advertised. To explore this, you test the hypotheses H0 : μ = 1.5, Ha : μ > 1.5 and you obtain a P-value of 0.052. Which of the following is true?
A. There is some evidence against H0, and a study using a larger sample size may be worthwhile.
B. You have failed to obtain any evidence for Ha.
C. This should be viewed as a pilot study and the data suggests that further investigation of the hypotheses will not be fruitful at the α = 0.05 significance level.
D. At the α = 0.05 significance level, you have proven that H0 is true.
3. An engineer designs an improved light bulb. The previous design had an average lifetime of 1200 hours. The new bulb had a lifetime of 1200.2 hours, using a sample of 40,000 bulbs. Although the difference is quite small, the effect was statistically significant. The explanation is:____.
a. that the sample size is very large.
b. that the mean of 1200 is large.
c. that new designs typically have more variability than standard designs.
d. all of the above.
Answers
Answer:
1. d. none of the above.
2. A. There is some evidence against H0, and a study using a larger sample size may be worthwhile.
3.a. that the sample size is very large.
Step-by-step explanation:
1. This experimental analysis is incomplete so none of the options provides the best solution. Therefore the correct answer is choice D.
2. The smallest value which provides basis for rejection for H0 at ∝= 0.05 is P= 0.05.
As P= 0.052 but we are not sure about other variables such as sample size. So option A is the best choice
A. There is some evidence against H0, and a study using a larger sample size may be worthwhile.
3. A sample of 40,000 bulbs will provide a wider range for the results. Therefore the sample size is too large to accurately predict the results .
Hence choice a gives the best answer that the sample size is too large.
