Answer:
height ≈ 11.9 units
Step-by-step explanation:
Construct a perpendicular bisector from the vertex to the base, thus splitting the triangle into 2 right triangles.
Using the sine ratio in one of these right triangles, then
sin48° = \(\frac{opposite}{hypotenuse}\) ( the opposite is the height h )
sin48° = \(\frac{h}{16}\) ( multiply both sides by 16 )
16 × sin48° = h , thus
h ≈ 11.9 ( to the nearest tenth )

Answers
Answer:
58% - 29/50(equivalent fraction)
Step-by-step explanation:
29/50 x 2 = 58/100 convert to decimal, 0.58, convert to percent, take decimal symbol and put it to digits to the right, 58%
the reason I doubled the fraction was to make it 100 so you can convert into a decimal a lot easier.
how I got 29/50, 29 out of 50 is the same thing is 29/50.

You have a bag of marbles with 630 marbles in it: 110 red, 230 green, and 290 blue. You pull out 1 marble, record the color, and replace it.
After you do this 100 times, the table shows the number of times each color was drawn:
Red Green Blue Total
21 35 44 100
Give exact, reduced answers.
a) What is the theoretical probability of drawing a blue?
b) What is the experimental probability of drawing a blue?
Answers
Answer:
a) The theoretical probability of drawing a blue marble is the ratio of the number of blue marbles to the total number of marbles in the bag, which is:
P(blue) = number of blue marbles / total number of marbles
= 290 / 630
= 29 / 63
So the theoretical probability of drawing a blue marble is 29/63.
b) The experimental probability of drawing a blue marble is the ratio of the number of times a blue marble was actually drawn to the total number of trials, which is:
P(experimental blue) = number of times a blue marble was drawn / total number of trials
= 44 / 100
= 11 / 25
So the experimental probability of drawing a blue marble is 11/25.

7. An administrator surveys a random sample of 48 out of 900 middle school students. Using the
survey results, the administrator predicts that 225 students are in favor of the new dress code.
How many of the 48 students surveyed were in favor of the new dress code?
Answers
Answer:
12 students
Step-by-step explanation:
225 is 25% of 900 and 25% of 48 is 12.
The number of students is 12 that is surveyed were in favor of the new dress code the answer is 12.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
An administrator surveys a random sample of 48 out of 900 middle school students.
Using the survey results, the administrator predicts that 225 students are in favor of the new dress code.
The proportion of sample = 225/900
= 0.25
In percent sample:
= 0.25x100 %
= 25%
A number of students surveyed were in favor of the new dress code:
= 25% of 48
= (25x48)/100
= 1200/100
= 12
Thus, the number of students is 12 that is surveyed were in favor of the new dress code the answer is 12.

Triangle JKL has vertices at J(−1, −5), K(−2, −2), and L(2, −4). Determine the translation direction and the number of units of the image of triangle JKL if vertex J′ is at (−1, −8).
3 units down
3 units up
7 units to the right
7 units to the left
Answers
Answer:
3 units down
Step-by-step explanation:
J(-1, -5) → J'(-1, -8)
The x coordinate of the vertex J is -1 and does not change in J' (it is still -1)
The y coordinate of J is -5, and for J' is -8. This means the translation direction of 3 units down. (-8- -5 = -3)

What values of b will cause 8x^2 x bx + 2 = 0 to have one real solution?
Answers
=======================================================
Explanation:
I'm assuming you meant to type 8x^2 + bx + 2 = 0
Compare this to ax^2 + bx + c = 0
We have a = 8, b = unknown, c = 2.
We'll use the discriminant formula which is D = b^2 - 4ac to find that
D = b^2 - 4ac
D = b^2 - 4*8*2
D = b^2 - 64
Since we want one real solution, we set the discriminant equal to zero.
D = b^2 - 64
0 = b^2 - 64
64 = b^2
b^2 = 64
b = sqrt(64) or b = -sqrt(8)
b = 8 or b = -8
So the equation 8x^2 + 8x + 2 = 0 has one solution. So does the equation 8x^2-8x+2 = 0

Step-by-step explanation:
Area of circle ( the shaded area ) for cone and cylinder is 18mm³
To find the radius:
We know Area of circle = πr²=18mm²
r²= 18/π
Volume of Cone =1/3πr²h=(1/3)π×18/π×4=24mm³
Volume of Cylinder=πr²h=π×18/π×4=72mm³
Therefore Volume of Cylinder=3× Volume of Cone

PLEASEE HEEELP! In the normal distribution, 68% of the data lies within 1 standard deviation A: __/6 of the mean, 95% of the data lies within 2 standard deviations of the mean, and 99.7% of the data lies within 3 standard deviations of the mean. Answer the following question without using the Z-table. If scores on a test are normally distributed with mean 1100 and standard deviation 100, what percentage of the test scores are: a) more than 1300? b) less than 1100?
Answers
Answer:
a) 2.5% b) 50%
Step-by-step explanation:
1300 is two standard deviations higher than the mean. Since 95% of the data is covered within two standard deviations to the left and right of the mean, 5% is not covered. So, we have 2.5% leftover on the left side of the curve, under 900, and 2.5% leftover on the right side of the graph that is above 1300.
The mean is 1100, so anything above or below the mean is exactly 50% in a normal distribution.
Answer:
Step-by-step explanation:
This is the Empirical Rule.
68% of the data lies within 1 standard deviation of the mean, and so on.
If the mean is 1100 and the standard deviation is 100, 1300 represents two standard deviations above the mean. Using a calculator with distribution functions, we type in normcdf(2,10000), obtaining 0.023. This tells us that 2.3 percent of test scores are more than 1300.
Less than 1100: Since the mean is 1100, the area under the standard normal curve is exactly 0.5 (corresponding to 50% of data are less than 1100).

A canoe travels 6 miles per hour downstream and 2 miles per hour upstream.
Let x represent the canoe's speed with no water current (still water) and y
represent the speed of the water current, in miles per hour. Then the situation
can be represented by this system of equations:
Choose the two correct options.
x + y = 6
x - y = 2
A. The speed of the canoe in still water is 4 miles per hour.
B. The speed of the canoe in still water is 2 miles per hour.
C. The speed of the water current is 4 miles per hour.
D. The speed of the water current is 2 miles per hour.
Answers
ANSWER : A AND D.
Step-by-step explanation:
the water current would be 2 mph and the canoe is 4 mph
See, 6miles downstream it would be 4mph of canoe + water boost ( 2 mph) = 6mph.
The canoe upstream would be 4mph - water resistance (2mph) = 2mph upstream.
The answers should be A and D.
