The answer is that there are 4 sprites. Because eight is half of sixteen so i add the numerator together and 2+2=4
Define a variable then write each phrase as an algebraic Expression. Two more than seven times Lindsay age
Answer:
7x + 2
Step-by-step explanation:
For the phrase given:
Two more than seven times Lindsay's age.
x = Lindsay's age
Two more than means that you will add 2,
...more than seven times Linday's age means you will multiply the variable by 7
7x + 2

Answer:
y=2 and x=1
Step-by-step explanation:
sub 2 into 1
3(15-7y) + 4y= 11
45 - 21y +4y =11
-21y+4y= 11-45
-17y= - 34
y=2
Therefore sub y into x equation
x=15-7(2)
x= 1
Answer:
3x + 4y = 11
x = 15 -7 y
3 (15-7y) = 11
45 - 21y + 4y = 11
45 - 17 y = 11
-17 y =11 -45
-17y ÷ -17 = -34 ÷ -17
y = 2
x = 15 - 7y
x = 15 - 7(2)
x = 15 - 14
x = 1
there for y = 2 and x = 1 is the solution

The answer in this picture is B(143)
Answer:
A
Step-by-step explanation:
180 _80 =100
180_65= 115
180_72 = 108
Then :
108 + 115 + 100 = 323
Then :
360 _ 323 = 37
Then :
180 _37 = 143
X _7 =143
X =150
The average of 15 test scores is 80. If the average of first eight test scores is 65 and that of the last eight test scores is 70, then the eighth score is 80.
True or False?
Answer:
FalseStep-by-step explanation:
The average of 15 test scores is 80.
The total is:
15*80 = 1200The average of first eight test scores is 65.
The total is:
8*65 = 520The average of last eight test scores is 70.
The total minus 8th score is:
8*70 - 80 = 480The sum gives us the total of 15 scores:
520 + 480 = 1000 < 1200The answer is FALSE

In an agricultural experiment, the effects of two fertilizers on the production of oranges were measured. Thirteen randomly selected plots of land were treated with fertilizer A, and 8 randomly selected plots were treated with fertilizer B. The number of pounds of harvested fruit was measured from each plot. Following are the results.
Fertilizer A
445 510 464 472 441 480 403 460 448
457 437 505 417
Fertilizer B
398 380 368 393 424 387 378 415
Required:
Construct a 95% confidence interval for the difference between the mean yields for the two types of fertilizer.
Answer:
The 95% confidence interval for the difference between the mean yields for the two types of fertilizer is approximately 92.5536 pounds < [tex]\bar{x}_{1}- \bar{x}_{2}[/tex] < 35.39 pounds
Step-by-step explanation:
The harvest from each plot treated with fertilizer A and fertilizer B are presented as follows;
Fertilizer A
445, 510, 464, 472, 441, 480, 403, 460, 448, 457, 437, 505, 417
Fertilizer B
398, 380, 368 393, 424, 387, 378, 415
The number of trials of fertilizer A, n₁ = 13
The number of trials of fertilizer B, n₂ = 8
The confidence level = 95%
α = 1 - 0.95 = 0.05
∴ α/2 = 0.025
The degrees of freedom, df = 8 - 1 = 7
[tex]t_{\alpha /2}[/tex] = 2.365
From Microsoft Excel, we get;
The standard deviation of the pounds of harvested fruits for the plots treated with fertilizer A s₁ = 30.71603
The mean of the pounds of harvested fruits for the plots treated with fertilizer A, [tex]\overline x_1[/tex] = 456.8462
The standard deviation of the pounds of harvested fruits for the plots treated with fertilizer B s = 18.99201
The mean of the pounds of harvested fruits for the plots treated with fertilizer B, [tex]\overline x_2[/tex] = 392.875
The 95% confidence interval, C.I. for the difference between the mean yields for the two types of fertilizer can be constructed with the following formula
[tex]C.I. = \left (\bar{x}_{1}- \bar{x}_{2} \right )\pm t_{\alpha /2} \cdot \sqrt{\dfrac{s_{1}^{2}}{n_{1}}+\dfrac{s_{2}^{2}}{n_{2}}}[/tex]
By variable substitution, we get;
[tex]C.I. = \left (456.8462- 392.875 \right )\pm 2.635 \times \sqrt{\dfrac{30.71603^{2}}{13}+\dfrac{18.99201^{2}}{8}}[/tex]
The 95% confidence interval for the difference between the mean yields for the two types of fertilizer [tex]C.I. \approx 63.9712 \pm28.5824[/tex], which can be expressed as 92.5536 lbs. < [tex]\bar{x}_{1}- \bar{x}_{2}[/tex] < 35.39 lbs.

ben positions his ladder against a wall so that the top of the ladder is 15 feet above the ground. about how long is his ladder?
A. 16.2 feet
B. 18.6 feet
C. 10.5 feet
D. 21 feet
Answer: 16.2 ft
Step-by-step explanation:
Using the Pythagorean theorem, if we let the length of the ladder be x,
[tex]6^{2}+15^{2}=x^{2}\\\\261=x^{2}\\\\x=\sqrt{261} \approx \boxed{16.2 \text{ ft}}[/tex]

Answer:A
Step-by-step explanation:
List the key features of the quadratic function y = –x2 + 4x – 3.
The key features of the quadratic function are
vertex is (2, 1)Axis of symmetry: x = 2The domain of the function is the set of all real valuesDetermining the key features of the quadratic functionFrom the question, we have the following parameters that can be used in our computation:
y = -x² + 4x - 3
A quadratic function is represented as
y = ax² + bx + c
By comapring the equations, we have
a = -1, b = 4 and c = -3
For the key features
Axis of symmetry: x = -b/2a
So, we have
x = -4/(2 * -1)
x = 2
The domain of the function is the set of all real values
For the vertex, we have
(h, k) = (symmetry, f(symmetry))
So, we have
y = -2² + 4(2) - 3
y = 1
So, the vertex is (2, 1)
