Mathematics
1 answer:
Ira Lisetskai [31]4 years ago

Answer:

x = 6

Step-by-step explanation:

\frac{9+x}{3x} = \frac{5}{6}

6(9+x) = 5(3x)

6*9 + 6*x = 5*3x

54 + 6x = 15x

54 = 15x - 6x

54 = 9x

x = 54/9

x = 6

check:

(9+6)/(3*6) = 5/6

15/18 = 5/6

What is the kinetic energy of a 3-kilogram ball that is rolling at 2 meters per second?
Serhud [2]
PE = m•g•h, where m is mass in kg, gis 9.8m/s2, and h is height above the earth in meters. If an object is on the ground, it's height above the earth is zero, so it has zero PE.

A Scout on top of a 1500-ft. mountain spots a campsite.
nlexa [21]

Answer: The distance from the campsite to the foot of the mountain is 2310 ft (approx)

Step-by-step explanation: We have been given that the scout on the mountain top has spotted a campsite and he did so while looking down from a 33° angle of depression. If we label his position as point A, the foot of the mountain as point B and the campsite as point C, then it means the scout has formed an angle of 57° between point A and point B. Now we have a right angled triangle ABC with angle A measuring 57°

Using the trigonometrical ratio of tangent

Tan A = opposite/adjacent

Tan 57 = BC/1500

1.5399 = BC/1500

When you cross multiply both sides you have

1.5399 × 1500 = BC

2309.85 = BC

Approximated to the nearest foot,

BC = 2,310 ft

Let μ denote the true average reaction time to a certain stimulus. For a z test of H0: μ = 5 versus Ha: μ > 5, determine the
noname [10]

Answer: 0.0708

Step-by-step explanation:

Let μ denote the true average reaction time to a certain stimulus.

To determine : The P-value for a z test of H0: μ = 5 versus Ha: μ > 5.

In the given set of hypothesis , the alternative hypothesis is right -tailed , so the test is a right tailed test .

Given test statistic : a) z= 1.47

Now, the p-value for the right tailed test :

P(z>1.47)=1-P(z\leq1.47)\ \ [\because P(Z>z)=1-P(Z\leq z)]

=1-0.9292=0.0708

[Using the p-value table for z]

Hence, the required P-value = 0.0708
