When a number is divided by 6 the answer is 37 with a remainder of 4 what is the number
Answer:
6 × 37 + 4 = 226 is the answer
Answer: 226
Step-by-step explanation: 37 times 6 equals 222 if you add 4 it gives you 226. 226 divided by 6 equals 37 with a remainder of 4. Hope this helps!
Select ALL the sets of three side lengths that will make a triangle.
3, 4, 8
7, 6, 12
5, 11, 13
4, 6, 12
4, 6, 10
Answer:
7 + 6
5 + 11
Step-by-step explanation:
the lengths of the two shorter sides of a triangle must add up to more than the length of the third side.
3 + 4 = 7 ≤ 8 no
7 + 6 = 13 > 12 yes
5 + 11 = 16 > 13 yes
4 + 6 = 10 ≤ 12 no
4 + 6 = 10 ≤ 10 no
===================================================
Explanation:
We'll use the triangle inequality theorem. Recall that this theorem says that a triangle is only possible if and only if adding any two sides leads to a sum larger than the third side.
Let's say we had a triangle with sides a,b,c. Such a triangle is only possible if all three conditions hold true
a+b > cb+c > aa+c > b----------------
Let's go through each answer choice to see if those conditions hold up.
Choice A. We have a = 3, b = 4, c = 8. Note that a+b = 3+4 = 7 which is not greater than c = 8. Therefore a+b > c is false, and we cannot make a triangle here. We don't need to check the other inequalities. I recommend you trying it out by cutting out slips of paper of these lengths. You'll find a triangle cannot be constructed. We can rule out choice A.Choice B. We have a = 7, b = 6 and c = 12. We can see that a+b = 7+6 = 13 which is larger than c = 12. So far, so good. Then note that b+c = 6+12 = 18 which is larger than a = 7. Finally, a+c = 7+12 = 19 which is larger than b = 6. Picking any two sides, adding them up, leads to a sum larger than the third side. A triangle is possible in this case. Choice B is one of the answers.Choice C. This time a = 5, b = 11, c = 13. You should find that a triangle is possible following the same steps as done in choice B above. Adding any two sides leads to a sum larger than the third side. Choice C is one of the answers. Choice D. Now we have a = 4, b = 6, c = 12. Then note a+b = 4+6 = 10 which is too small compared to c = 12. Meaning a+b > c is false. A triangle isn't possible. Cross choice D off the list.Choice E. In this case, a = 4, b = 6 and c = 10. Adding the first two values gets us a+b = 4+6 = 10 which is not larger than c = 10. If you used slips of paper, you'd find that a straight line is formed rather than a triangle. Cross choice E off the list.To wrap things up, only choice B and choice C are possible triangles because adding any two sides leads to a sum larger than the third side.

7.5:4.5
5 is to 3
15/5
45/27
Answer:
15/5
Step-by-step explanation:
because 7.5 ÷ 4.5 = 1.66667
5 ÷ 3 = 1.66667
and 45 ÷ 27 = 1.66667
but 15 ÷ 5 = 3 therefore it's the off one out.

AB has points A at (2,−5) and B at (5,−3).
AB iis reflected across the y-axis and then translated 3 units right. What are the coordinates of the endpoints of the image A′B'?
9514 1404 393
Answer:
A'(1, -5)B'(-2, -3)Step-by-step explanation:
Reflection over the y-axis and translation 3 right is modeled by the transformation ...
(x, y) ⇒ (-x +3, y)
Then the image end points are ...
A(2, -5) ⇒ A'(-2+3, -5) = A'(1, -5)
B(5, -3) ⇒ B'(-5+3, -3) = B'(-2, -3)
_____
In the attached figure, the reflection is shown as A'B' in light purple. The line after the final translation is shown as A"B" in blue.
It has been observed that some persons who suffer acute heartburn, again suffer acute heartburn within one year of the first episode. This is due, in part, to damage from the first episode. The performance of a new drug designed to prevent a second episode is to be tested for its effectiveness in preventing a second episode. In order to do this two groups of people suffering a first episode are selected. There are 45 people in the first group and this group will be administered the new drug. There are 75 people in the second group and this group will be administered a placebo. After one year, 12% of the first group has a second episode and 14% of the second group has a second episode. Conduct a hypothesis test to determine, at the significance level 0.1, whether there is reason to believe that the true percentage of those in the first group who suffer a second episode is less than the true percentage of those in the second group who suffer a second episode.
A. [ z < -1.65, RHo].
B. [ z < -1.65 and z > 1.65, FRHo].
C. [z > 1.65, FRHo].
D. [z < -1.65 and z > 1.65, FRHo].
E. [z > -1.65 and z < 1.65, RHo].
F. None of the above.
Answer:
F. None of the above.
Step-by-step explanation:
Let the null and alternate hypothesis be
H0: p1 ≥ p2 against the claim Ha: p1 < p2
the significance level is 0.1
The critical region is z < z∝= 1.28
The test statistic is
Z= ( p^1-p^2)- (p1-p2)/√p1^q1^/n1 + p2^q2^/n2
Here n1= 45 , n2= 75
p1= 0.12 p2= 0.14
q1= 0.88 q2= 0.86
z= 0.12- 0.14/√0.12*0.88/45 +0.14*0.86/75
Z= 0.02/ √0.00235 + 0.00161
Z= 0.02/0.062891
z= 0.318
The calculated value of z= 0.318 lies in the critical region z < 1.28
therefore accept Ha.
All of the options are incorrect as the critical value for one tailed test for 0.1 is 1.28 .

Pleaseeee helpppppppp!!!
Answer:
x = 46°
Step-by-step explanation:
Appling the principle of supplementary angle in Geomentry.
Supplementary angle: These are angles that sum up to 180°
From the diagram above, x and 134° are supplementry because they sum up to 180°.
Therefore,
134+x = 180 (Supplementary angle)
Solve for x
x = 180-134
x = 46°
Therefore, the value of the missing angle is 46°

A bag contains 7 red marbles, 8 blue marbles and 4 green marbles. If three marbles
are drawn out of the bag, what is the probability, to the nearest 100oth, that all three
marbles drawn will be blue?
Answer:
Step-by-step explanation:
A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.
Total = 18 marbles.
Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.
Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.

A cyclist travels 4.9 km in 30 minutes.
What is his average speed in km/h?
Answer:
9.8 km/h
Step-by-step explanation:
Since there are 60 minutes in an hour, we can find his speed in km/h by multiplying 4.9 by 2.
4.9(2)
= 9.8
This means that he will travel 9.8 km in 60 minutes (1 hour).
So, his average speed is 9.8 km/h
