In AMNO, The Measure Of 20=90, MN = 99 Feet, And OM = 52 Feet. Find Themeasure Of M To The Nearest Degree.

Answers

Answer 1

Answer:

x = 58 degrees

Step-by-step explanation:

Using the SOH CAH TOA trigonometry identity

hypotenuse =99

adjacent = 52

angle of elevation  = x

cos theta = adj/hyp

cos x = 52/99

x = arccos (52/99)

x = arccos(0.5253)

x = 58 degrees ( to the nearest degree)

Answer:

Step-by-step explanation:

The angle measuring 152 is split up, per se, into 2 angles. One of them is a 90 degree angle, as demonstrated by the little square that is above the 152. That 90 degree angle is on a straight line with the 28 degree angle and the angle measured as x. A straight line has a measure of 180. Therefore, 180 - 28 - 90 = x, so x = 62

5x - y = 6

x + 6y = 4

5B. Using the balanced seesaw shown, find the ratio of lengths a/b in lowest terms.

Answers

Answer:

Lowest terms is 7:6

Step-by-step explanation:

A = 63

B = 54

Ratio is a:b = 63:54

63:54

Reduce 63 to lowest terms to get 7 by dividing 9.

63 ÷ 9 = 7

Reduce 54 to lowest terms to get 6 by dividing 9.

54 ÷ 9 = 6

So the reduced form 63:54 in ratio is 7:6.

7:6

I hope this helped!

Answer:

6:7

Step-by-step explanation:

weight * distance = weight * distance,

so 63 * d1 = 54 * d2

LCM(63,54) = 378

378÷63 = 6

378÷54 = 7

so the answer is 6:7

Some researchers have conjectured that stem-pitting disease in peach-tree seedlings might be controlled with weed and soil treatment. An experiment is conducted to compare peach-tree seedling growth when the soil and weeds are treated with one of two herbicides. In a field containing 20 seedlings, 10 are randomly selected throughout the field and assigned to receive herbicide A. The remainder of the seedlings is assigned to receive herbicide B. Soil and weeds for each seedling are treated with the appropriate herbicide, and at the end of the study period, the height in centimeters is recorded for each seedling. The following results are obtained: Herbicide A = 94.5 cm s1 = 10 cm Herbicide B = 109.1 cm s2 = 9 cmWhat is a 90% confidence interval (use the conservative value for the degrees of freedom) for μ2 – μ1?
a. 14.6 ± 7.00
b. 14.6 ± 7.38
c. 14.6 ± 7.80
d. 14.6 ± 9.62

Answers

Answer:

A. 14.6 ± 7.00

Step-by-step explanation:

Formula for the confidence interval between the two mean is;

CI = (μ2 - μ1) ± z√[((s1)²/n1) + ((s2)²/n2)]

We are given;

μ1 = 94.5

μ2 = 109.1

s1 = 10

s2 = 9

n1 = 10

n2 = 10

The z-value at confidence interval of 90% is 1.645

Thus;

CI = (109.1 - 94.5) ± 1.645√[(10²/10) + (9²/10)]

CI = 14.6 ± 7.00

Zak buys 6 gallons of fruit punch. He has
coupons for $0.55 off the regular price of
each gallon of fruit punch. After using the
coupons, the total cost of the fruit punch is
$8.70. Determine the regular price of a
gallon of fruit punch.​

Answers

$8.70 is the total cost without the coupons. He gets 6 gallons. He gets $0.55 off per gallon.

To find the total price Zak got off, multiply 6 and $0.55. 6 x $0.55 = $3.30, so he got $3.30 off.

To find the total price. Add the total cost without the coupons + the amount the coupons saved him.
$8.70 + $3.30 = $12

To find the price per one gallon, divide the total price / number of gallons

$12/6 = $2. The regular price is $2 a gallon

Service time for a customer coming through a checkout counter in a retail store is a random variable with the mean of minutes and standard deviation of minutes. Suppose that the distribution of service time is fairly close to a normal distribution. Suppose there are two counters in a store, customers in the first line and customers in the second line. Find the probability that the difference between the mean service time for the shorter line and the mean service time for the longer one is more than minutes. Assume that the service times for each customer can be regarded as independent random variables. Round your answer to two decimal places (e.g. 98.76).
