Step-by-step explanation:
Area of parallelogram =b×h
= 7×x
= 7x cm²
For number one A we need to multiply 5x5 because exponents make you multiply the base number by the exponent the ammount of times the exponest value is. This would give is 25-6 which equals 19
number 1 B we need to add the 8 and the 3 to give us eleven over five. thats the simplest answer to this question
2a we need to multiply the 5 into the parenthesis
then we add. The answer would be 28
for 2b the answer would be 9 2/9
ill let you solve the rest. hope this helped. dont forget to leave a heart give it 5 stars and make it the brainliest answer!!
Answer:
- The means for both data sets are equal.
- The range of the number of pages Lionel read is greater than the range of the number of pages Aaron read.
- The range of the number of pages that Lionel read is 75.
Step-by-step explanation:
Given
Lionel
90, 45, 30, 25, 15
Aaron
55, 19, 40, 16, 75
in the first case; For Lionel;
Mean = (90+45+30+25+15
)/5 = 41 and
Range = (90-15)=75
The second case; Aaron
Mean = (55+19+40+16+75)/5 = 41 and
Range = (75-16)= 59
Therefore;
Both data sets have the same mean but different range.
The range of the number of pages Lionel is 75, which is greater than the range of the number of pages Aaron read, which is 59.
The problem statement suggests you use a calculator. A graphing calculator can give the answers you seek.
a) The calculator shows 5 solutions:
{5π/23, 5π/17, 25π/23, 25π/17, 45π/23}
These have approximate decimal values of
{0.6830, 0.9240, 3.4148, 4.6200, 6.1466}
b) The calculator shows 2 solutions with approximate decimal values of
{1.2925, 4.4341}
c) The calculator shows 2 solutions with approximate decimal values of
{1.3694, 4.9137}
_____
This (desmos) calculator displays intercepts to 3 decimal places. Since you want 4 decimal places, some additional refinement of the answer was necessary. That was accomplished using Newton's method iteration. The details are not shown. A suitable graphing calculator (for example, a TI-84) will supply the intercept coordinates to full calculator accuracy.
The circumference of a circle is C = 2<span>πr
Given C = 36</span><span>π, we can solve for the radius r:
r = C/2</span>π = 36π/2<span>π = 36/2 = 18 cm (ANSWER)
