Answer:
A
Step-by-step explanation:
● first one:
The diagonals of a rhombus are perpendicular to each others wich means that they form four right angles.
STP is one of them so this statement is true.
● second one:
If ST and PT were equal this would be a square not a rhombus.
● third one:
If SPQ was a right angle, this woukd be a square.
● fourth one:
Again if the diagonals SQ and PR were equal, this would be a square.
Answer:
k=11
Step-by-step explanation:
Slope is calculated by dividing the change in y over the change in x. The change in x for these points is 4. This leaves us with y/4 as the slope, which must equal 2. Divide both sides of the equation (y/4=2) by 4. y=8
Now add 8 to the y coordinate of (1,3) in order to get a y value of 11 for the second coordinate.

Step-by-step explanation:
(-3,6)
ANSWER
Positive:
Negative;
EXPLANATION
The given point is
This is a point in the second quadrant.
In this quadrant, only the sine function and its reciprocal, the cosecant are positive.
The cosine, tangent,cotangent, and cosecant functions are negative.
Answer:
95% of premiums that are between $600 and $1300.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 950
Standard deviation = 175
Estimate the percent of premiums that are between $600 and $1300.
600 = 950 - 2*175
So 600 is two standard deviations below the mean.
1300 = 950 + 2*175
So 1300 is two standard deviations above the mean
By the Empirical Rule, 95% of premiums that are between $600 and $1300.
