Answer:
it would be d = C/π
Step-by-step explanation:
Answer:
7000x- 28% = 1960
so the answer is 28%
Step-by-step explanation: Its just trial and error. If you have more questions on this topic just try using the calculator and use the x and - method above :)
Answer:
The percentage is k = 2.3%
Step-by-step explanation:
From the question we are told that
The population mean is
The standard deviation is
Given that the sales are normally distributed and that students at a certain school who sell at least 75 magazine subscriptions win a prize then the percent of the fourth grade students receive a prize is mathematically represented as
Generally
So
From the standardized normal distribution table
=>
The percentage of the fourth grade students receive a prize is
k = 0.023 * 100
k = 2.3%
Yes and no because you add two times and in it would not ealq yes becaues 19 and6
Part 3) <span>Given triangle XYZ as shown at right find YZ rounded to the nearest tenth
we know that
</span><span>the sum of the internal angles of a triangle add up to 180 degrees
</span>so
m∠X=180-[55+29]----> 96°
applying the law of sines
YZ/sin X=35/sin 55°------> YZ=35*sin 96/sin 55-----> YZ=42.49
YZ=42.5 units
the answer Part 3) isYZ=42.5 unitsPart 4)
we know that
OQ/NQ=PR/NR
NQ=4X+(2X+2)---> 6X+2
OQ=2X+2
PR=15
NR=24+15----> 39
(2X+2)/(6X+2)=15/39
39*(2X+2)=15*(6X+2)
78X+78=90X+30
90X-78X=78-30
12X=48
X=4
The answer part 4) isx=4Part 5) A trapezoid is show below. Calculate the measure of angle x. Round to the nearest tenth of a degree
see the picture with letters attached to better understand the problem
we know that
BC=36-28-----> 8 ft
sin x=BC/AC-----> sin x=8/12
x=arc sin(8/12)-------> x=41.81°------> x=41.8°
the answer Part 5) isx=41.8°
