Answer:
[tex]9k^{2} - 25k - 44[/tex]
Step-by-step explanation:
A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 41 specimens and counts the number of seeds in each. Use her sample results (mean = 54.7, standard deviation = 5.3) to find the 90% confidence interval for the number of seeds for the species. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).
Answer:
(53.3; 56.1)
Step-by-step explanation:
Given that:
Sample size, n = 41
Mean, xbar = 54.7
Standard deviation, s = 5.3
Confidence level, Zcritical at 90% = 1.645
Confidence interval :
Xbar ± Margin of error
Margin of Error = Zcritical * s/sqrt(n)
Margin of Error = 1.645 * 5.3/sqrt(41)
Margin of Error = 1.362
Lower boundary = 54.7 - 1.362 = 53.338
Upper boundary = 54.7 + 1.362 = 56.062
(53.3 ; 56.1)

If the parent function is y = 3^x,which is the function of the graph?
Answer:
[tex]y = 3x + _ 2[/tex]
Step-by-step explanation:
The graph of y = 3^x will pass through the point (0, 1). This graph passes through the point (-3, 1); it has been shifted to the left 3 units.
A function can be translated, or shifted, to the left by adding a number to x before the function is applied; in this case, it means adding 3 to x before the base is raised to the power. This gives us
This graph has also been translated, or shifted, down 2 units. This can be done by subtracting a number from the end of the function; this gives us
The gas mileage for Peter's car is 21 miles per gallon when the car travels at an average speed of 50 miles per hour. The car's gas tank has 17 gallons of gas at the beginning of a trip. If. Peter's car travels at an average speed of 50 miles per hour, which of the following functions fmodels the number of gallons of gas remaining in the tank thours after the trip begins? 21 A. f(t) = 17 - 50T B. f(t) = 17 - 500 21 17-500 C. f(t) 17-210 50 D. f(t) = 21
Answer:
f(t)= 17- 50t/21
Step-by-step explanation:
distance covered after t hours= 50t miles
number of gal.=50t×1/21 =50t/21 gal.
f(t)=starting-consuming= remaining
= 17-50t/21
Answer:f(t)= 17- 50t/21
f(t)= 17- 50t/21
Step-by-step explanation:
distance covered after t hours= 50t miles
number of gal.=50t×1/21 =50t/21 gal.
f(t)=starting-consuming= remaining
= 17-50t/21
hello! is y = 3x - 3 proportional or non-proportional?? please help!
A proportional graph is a straight line that goes through the origin while a non-proportional graph is a straight line that doesn't go through the origin.
y = mx + b
the b represents the y-intercept, so -3 is the y-intercept in the equation y = 3x -3
therefore, the line doesn't go through the origin and is a non-proportional equation
Solving the following system using substitution method.
y=3x-6
y=x-10
Answer:
x = -2, y = -12
Step-by-step explanation:
x - 10 = 3x - 6
-2x = 4
x = -2
y = -2 - 10
y = -12
Which equation finds the area of a square with a side length of 5 n Superscript 4 units?
(5 n Superscript 4 Baseline) squared = 25 n Superscript 8 square units

find the measure for each angle indicated
Step-by-step explanation:
7. 180 -92 -67 =21. 180-21 = 159
8.180-144 = 36 + 94 = 130 180-130 = 50
Answer:
Step-by-step explanation:
TWO RULES:
⊳ Angles in a triangle add up to 180
⊳ Angles on a straight line also add up to 180
=================================================================
QUESTION 1
92 + 67 + x = 180
x + 159 = 180
x = 21
180 - 21 = 159
? = 159
=================================================================
QUESTION 2
144 + x = 180
x = 36
94 + 36 + ? =180
130 + ? =180
? = 50

Answer:
θ = 76°
Step-by-step explanation:
Using the cofunction identity
sinx° = cos(90 - x)°, then
sin14° = cos(90 - 14)° = cos76°
That is θ = 76°
Answer:
in radians o= 0.13716675
Step-by-step explanation:
cos(0)=0.9906074
O= arccos(0.9906074)

Find n(A) for the set.
1) A = 200, 201,
202, ..., 2000)
A) n(A)= 1801
B) n(A)= 4
C) n(A)=2000
A=200,201,202.........,2000
Here, it forms an AP with common difference 1
Let the number of terms in the set be n
[tex] T_{n} = a+(n-1)d \\\\ 2000= 200+(n-1) \\\\ 200+n-1= 2000 \\\\ => n=2000-199= 1801[/tex]
Hence,n(A)=1801
The Riddle Family has a total monthly budget of $3,400. If the utilities represent 15% of the budget, then how much money is the Riddle Family spending on
utilities each month?
Answer: $510
Step-by-step explanation:
Total monthly budget = $3,400.
Percentage of total budget spent on utilities = 15%
The amount that the Riddle Family spending on utilities each month will then be:
= 15% × $3400
= 15/100 × $3400
= 0.15 × $3400
= $510
Answer:
0.15 * 3400 = $________ utilities cost per month
Multiply the monthly cost by 12.

The diagonals of a quadrilateral are 12 and 10. Is
this a parallelogram rectangle? Explain your answer
Answer:
the answer is no.a parallelogram is not a rectangular but the opposite is true. the reason is a cause of parallelogram's diagonals.they might not be equal in parallelogram but in rectangular they must be equal.
Step-by-step explanation:
Answer:
If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram. So yes it is a parallelogram.
Step-by-step explanation:
Diagonals of parallelogram are not necessarily equal. This is a known property of a parallelogram. If all angles are equal, then it means its opposite angles are also equal which is a condition for a quadrilateral to be called parallelogram. If all sides are equal then, opposite sides are also equal.
