Step-by-step explanation:
If θ is a second-quadrant angle and cosθ = - 2/3, then tanθ=
a. -2 (sqrt 5)/5
b. - (sqrt 5)/2
c. - (sqrt 5)/3
Answer:
since in second quadrant cos θ is negative.
Cos θ=b/h=2/3
b=2
h=3
p=√(3²-2²)
p=√5
Now
Tan θ=p/b=√5/2
since in second quadrant tanθ is negative
so
Tanθ=-√5/2
b. - (sqrt 5)/2
In second Quadrant cos is negative
cosØ=b/h=2/3So
b=2 and h=3
Perpendicular
p²=h²-b²p²=3²-2²p²=5p=√5tanØ=-p/b =-√5/2
What is the area of this figure?
Answer:
[tex] 220.5 \: {yd}^{2} [/tex]
Step-by-step explanation:
Area of the figure = Area of the arc with radius 10 yd and central angle 90° + Area of rectangle with dimensions (10 + 5 - 3 = 12) 12 yd and (7 + 6 - 4 = 9) 9 yd + Area of square with dimension 4yd + Area of rectangle with dimensions 3 yd by 2 yd + Area of triangle with base 3 yd and height (5 + 3 = 8) 8 yd.
[tex] = \frac{90 \degree}{360 \degree} \times 3.14 {(10)}^{2} + 12 \times 9 + {4}^{2} \\ + 3 \times 2 + \frac{1}{2} \times 3 \times 8 \\ \\ = \frac{1}{4} \times 314 + 108 + 16 + 6 + 12 \\ \\ = 78.5 + 142 \\ \\ = 220.5 \: {yd}^{2} [/tex]

James has 16 more game cards than Fay. If they have 48 game
cards altogether, find the number of game cards James has.
Answer:
James has 32 game cards
Step-by-step explanation:
X=Fay

X(Fay) + (x+16) James =48
x+x+16=48
2x=32
x=16 Fay
x+16 James
16 + 16=32 James
check answer:
16 Fay + 32 James =48
16+32=48
48=48
Plssss helppp with part B
Answer:
12:7
Step-by-step explanation:
From the diagram shown;
QS/PS = RT/PT
QS/PS = RT/PS+ST
QS/14 = RT/14+10
QS/14 = RT/24
14RT = 24QS
RT/QS = 24/14
RT/QS = 12/7
Hence the required ratio is 12:7

Select the statement that is FALSE. The range is never greater than the greatest value of a data set. The interquartile range is the difference between the highest and lowest values in the middle of a data set. The range is the difference between the largest and smallest values of a data set. The mean is never greater than the greatest value of a data set.
Answer:
The interquartile range is the difference between the highest and lowest values in the middle of a data set.
Step-by-step explanation:
The range is the difference between the maximum and minimum value, hence, it cannot be greater than the maximum value, which is the greatest value in a dataset, the highest value a range could have being equal to the maximum value when the minimum vlaue of the dataset is equal to 0.
The mean is the average value of a dataset, hence, it cannot be greater than the maximum value.
The interquartile range is the middle 50% or half of a dataset and not the difference between the highest and lowest middle values in the middle. It is obtained by taking the difference of the upper and lower QUARTILE.

What's the difference in the range of temperatures recorded last year and the range of temperatures recorded two years ago?
Answer:
0°C
No Modal
Step-by-step explanation:
The range of a set is calculated by subtracting the max value by the lowest value in the set. Which using the data provided would be the following
range Last Year: 19 - 9 = 10
range 2 years ago: 17 - 7 = 10
Since we see that the range for both sets is 10 degrees then the difference is 0 degrees.
There is no modal temperature last year since no same temperature has appeared more than once.

What are the characteristics of a function and how can we identify them?
Answer:
A function is a mathematical relationship where all inputs must have exactly one output. If there is more then one output for one input, then the relationship is not a function.
x is most of the time the input and y the output for an equation:
y = 2x
of course the input and output could be any variable.

The following sample observations were randomly selected. x53634468y1315712131195 Click here for the Excel Data File Determine the coefficient of correlation and the coefficient of determination. Interpret the association between x and y. (Round your coefficient of determination to 4 decimal places. Round all other answers to 2 decimal places.

Answer:
R = -0.8908
R² = 0.7935
Step-by-step explanation:
Given the data:
X :
5
3
6
3
4
4
6
8
Y :
13
15
7
12
13
11
9
5
Using technology, we could obtain the correlation Coefficient (R) using the Pearson correlation Coefficient calculator :
R = -0.8908 ; This means that there is a strong negative relationship between x and y. That is, an increase in x will lead to a corresponding decrease in y and vice versa.
The Coefficient of determination (R²) ; is obtained by taking the squared value of R
R² = (-0.8908)² = 0.7935 ; This means that about 79.35% of the variation is y is explained by the regression line.
