A random sample of three-year-old thoroughbred racehorses is taken, and the 95% confidence interval for the true mean height (in inches) is calculated to be (62.0, 68.4). Data about horses from the historical record of the three-year old thoroughbred racehorses who have run in the Kentucky Derby is examined, and the mean height is calculated to be 68.25 inches. Does this sample provide convincing evidence that three-year-old thoroughbred racehorses are, on average, shorter than those that run in the Kentucky Derby
Answers
Options :
Yes, 68.25 is near the top of the confidence interval.
Yes, the value of 68.25 is a number in the confidence interval.
Yes, 68.25 is much higher than the sample mean of all three-year-old thoroughbred racehorses, which was 65.2 inches.
No, the value of 68.25 is a number in the confidence interval.
No, the horses that run in the Kentucky Derby are a subset of all three-year-old thoroughbred racehorses
Answer:
No , the value of 68.25 is a number in the confidence interval.
Step-by-step explanation:
The confidence interval gives a range if values which is used in establishing the significance of an hypothesis. If the true mean falls within the confidence interval drawn, then our finding is insignificant and the null hypothesis will stand. However, if the true mean does not fall within the interval, then our result is considered significant and the null is thus rejected.
Since true mean exists within the confidence interval, then we conclude that the sample does not provide convincing evidence that three-year-old thoroughbred racehorses are, on average, shorter than those that run in the Kentucky Derby
Marcia is mixing lemonade. She use 3 parts water to 1 part syrup. If she has 9 parts water, how much syrup will she need to complete the mixture?
Answers
Answer:
if Marcia uses 9 parts water, that mean she will have to use 3 parts syrup
Step-by-step explanation:
this is ratios,
so to find out how many syrup she needs, you need to see how much she used water from the original recipe
so:
9 ÷ 3 = 3
so she multiplied three to get to nine, so we have to do the same to the syrup
_ ÷ 1 = 3
or:
3 × 1 = 3
so the answer is 3

Find the value of x such that the data set has the given mean.
99, 122, 107, 114, 107, x; mean 114
Answers
9514 1404 393
Answer:
x = 135
Step-by-step explanation:
The sum of the differences from the mean of the known numbers is
-15 +8 -7 +0 -7 = -21
The value of x must have a difference from the mean that is the opposite of this sum. (That is, the total of differences from the mean of all the numbers must be zero.)
x = 114 +21
x = 135
The denominator of a fraction is 7 more than the numerator. If 1 is added to the numerator and 6 is added to the denominator, the value of the fraction will be ½. Find the numerator and the denominator.
Answers
Answer:
Let x=numerator,
y=denominator.
y=x+7 - - - - - (i)
(x+3)/(y+3) = 2/3
(Cross multiply)
3(x+3)=2(y+3)
3x+9=2y+6
(subtract 9 from both sides)
3x+9–9=2y+6–9
3x=2y+6–9
3x=2y-3 - - - - - - - (ii)
(substitute the value of equation (i) into (ii))
3x=2(x+7)-3
3x=2x+14–3
3x=2x+11
(subtract 2x from both sides)
3x-2x=2x+11–2x
x=11.
(substitute the value of x into equation (i))
y=7+11
y=18.
so numerator =11,
numerator =11,denominator = 18.
So original fraction is 11/18.
3/11th of original fraction is
= 11/18 x 3/11
= (11x3)/(18x11)
= 3/18

13-2=2x-x
11=x
numerator =x+1=11+1=12
therefore numerator is 12
for denominerator
substitute the value of x in (7+x+6)
=7+11+6

Identify the distance between points (3,7,1) and (9,6,7), and identify the midpoint of the segment for which these are the endpoints. Round to the nearest tenth, if necessary.
Answers
Step-by-step explanation:
[tex]range = (3,7,1) - (9,6,7) \\ = ( - 6,1, - 6) \\ distance = \sqrt{ {x}^{2} + {y}^{2} + {z}^{2} } \\ = \sqrt{ {( - 6)}^{2} + {1}^{2} + {( - 6)}^{2} } \\ = \sqrt{73} \\ = 8.5 \: units[/tex]
The distance between points (3,7,1) and (9,6,7) is 8.54 units and the midpoint of the segment is (6, 6.5, 4).
What is Distance?The length along a line or line segment between two points on the line or line segment.
Distance=√(x₂-x₁)²+(y₂-y₁)²
We need to find the distance between points (3,7,1) and (9,6,7).
Distance=√(9-3)²+(6-7)²+(7-1)²
=√6²+(-1)²+(6)²
=√36+1+36
=√73
=8.54 units
So the distance between the two points is approximately 8.5 units.
To find the midpoint of the segment between the two points, we use the midpoint formula:
midpoint = ((x₁+x₂)/2, (y₁+y₂)/2, (z₁+z₂)/2)
Using the given points, we have:
midpoint = ((3+9)/2, (7+6)/2, (1+7)/2)
= (6, 6.5, 4)
So the midpoint of the segment is (6, 6.5, 4).
Hence, the distance between points (3,7,1) and (9,6,7) is 8.54 units and the midpoint of the segment is (6, 6.5, 4).

The shapes which have all the properties shown are C. Rectangle and E. Square.
What are Isosceles Triangles?Isosceles triangles are defined as the triangles for which two sides or two angles are equal to each other.
Given properties are,
At least 2 sides of equal length
2 pairs of parallel sides
At least 2 right angles
Since the property includes that 2 pairs of parallel sides, it must contain 4 sides in total.
So triangle can't be a possible shape.
Parallelogram can't also be possible since there are no right angles.
Only right trapezoids are possible since the other ones will not have al least two right angles.
Rectangle and square are possible.
Hence the correct shapes are Rectangle and Square.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The scale on the map is
3 cm : 500 miles
a)
Let the distance between the 2 cities be = A
Now , the equation is
When the distance between the 2 cities is 500 miles , the scale on the map is 3 cm
So ,
3 cm = 500 miles
9 cm = 3 x 3 cm
9 cm = 500 x 3 miles
= 1500 miles
Therefore , the distance between the two cities is 1500 miles
b)
The distance between the two national park is 750 miles
Now , the equation is
When the distance between the 2 cities is 500 miles , the scale on the map is 3 cm
So ,
500 miles = 3 cm
1 mile = 3 / 500 cm
750 miles = ( 3 x 750 ) / 500 cm
750 miles = 3 x 1.5 cm
= 4.5 cm
Therefore ,
The distance between the two national parks on the map is 4.5 cm
Hence , a) The distance between the two cities is 1500 miles
b) The distance between the two national parks on the map is 4.5 cm
