Step-by-step explanation:
the angle is 90 degree
therefore, <1 + <2 = 90
(x+51) + (2x) = 90
3x +51 = 90

Two competing headache remedies claim to give fast-acting relief. An experiment was performed to compare the mean lengths of time required for bodily absorption of brand A and brand B. Assume the absorption time is normally distributed. Twelve people were randomly selected and given an oral dosage of brand A. Another 12 were randomly selected and given an equal dosage of brand B. The length of time in minutes for the drugs to reach a specified level in the blood was recorded. The results follow: x s x n Brand A 20.1 8.7 12 Brand B 18.9 7.5 12 a) Is there sufficient evidence that these drugs differ in the speed at which they enter the blood stream?

A surveyor leaves her base camp and drives 43km
on a bearing of 032 degrees. She then drives 28km
on a bearing of 154 degrees. How far is she then
from her base camp and what is her bearing from
it?
Answers
Answer:
1. The distance from the base camp is 37 Km
2. The bearing from the base camp is 72°
Step-by-step explanation:
Please see attached photo for explanation.
1. Determination of the distance from the base camp.
In the attached photo, x is the distance from the base camp. The value of x can be obtained by using the cosine rule formula. This is illustrated below:
Side opposite A = a = 28 Km
Side opposite C = c = 43 Km
Angle B = 58°
Side opposite B = b = x =?
b² = a² + c² – 2ac Cos B
x² = 28² + 43² – 2 × 28 × 43 Cos 58
x² = 784 + 1849 – 2408 × 0.52991
x² = 2633 – 1276
x² = 1357
Take the square root of both side
x = √1357
x ≈ 37 Km
Thus, the distance from the base camp is 37 Km.
2. Determination of the bearing from the base camp
We'll begin by calculating the value of θ in the attached photo. This can be obtained by using sine rule formula as shown below:
Side opposite A = a = 28 Km
Side opposite B = b = x = 37
Angle B = 58°
Angle A = θ =?
a/Sine A = b/SineB
28/Sine θ = 37/Sine 58
Cross multiply
37 × Sine θ = 28 × Sine 58
Divide both side by 37
Sine θ = 28 × Sine 58 /37
Sine θ = 28 × 0.8480 / 37
Sine θ = 0.6417
Take the inverse of sine
θ = Sine¯¹ 0.6417
θ = 40
Finally, we shall determine the bearing from the base camp. This can be obtained as follow:
Bearing from the base camp = 32 + θ
θ = 40
Bearing from the base camp = 32 + 40
Bearing from the base camp = 72°

Step-by-step explanation:
Step 1. Convert the expression
7 can also be seen as 7/1
Step 2. Multiply the fractions
7/1 × 5/8
you do this step by multiplying the numerators together for your top number, and your denominators together for your bottom number.
7×5= 35 (numerator)
1×8=8 (denominator)
the answer is 35/8 or 4 3/8 as a mixed fraction.
Diego has run 4/5 of a race distance. He has run 7 2/3
Answers
“Diego has run 4/5 of a race distance. He has run 7 2/3 miles. How long is the race? Or “how many miles does he have left?”
How long is the race? = 9 7/12 miles
4/5x = 7 2/3
4/5x = 23/3
x = 23/3 • 5/4
x = 115/12
x = 9.58333
x = 9 7/12 miles
How many miles does he have left? = 1 1/12 miles
1/5 • 115/12 = 115/60 = 1.916666
= 1 55/60 = 1 11/12 miles

Step-by-step explanation:
A music therapist was interested in investigating whether listening to music or composing music had an influence on both anxiety levels and oxygen saturation in children who were hospitalized for asthma-related illnesses. Thirty-two children spent 20 minutes listening to classical waltzes played on a piano. On a different day, they spent 20 minutes composing their own short pieces of music using a software program.
When listening to music: For the physiological measure, the critical value for t was larger than the test statistic for the observed data. For the anxiety measure, the critical value for t was smaller than the test statistic for the observed data.
When composing music: For the physiological measure, the critical value for t was larger than the test statistic for the observed data. For the anxiety measure, the critical value for t was larger than the test statistic for the observed data.
When writing the results of the music therapist's study, which of these statements reflects the correct conclusions that should be drawn from the results and then included as part of the interpretation paragraph?Question 8 options:
a) Music therapists should make pediatric asthma patients compose music in order to increase their oxygen saturation.
b) Music therapists should make pediatric asthma patients listen to music in order to reduce their anxiety.
c) Pediatric asthma patients should listen to music in order to increase their oxygen saturation.
d) Additional information is needed to draw a proper conclusion.
Answers
Answer:
The correct conclusion is;
d) Additional information is needed to draw a proper conclussion
Step-by-step explanation:
The given parameters are;
When listening to music;
Physiological measure Critical t > Test statistic Accept H₀
Anxiety measure Critical t < Test statistic Reject H₀
When composing music;
Physiological measure Critical t > Test statistic Accept H₀
Anxiety measure Critical t > Test statistic Accept H₀
When the test statistic is larger the critical 't'
Therefore, the test suggest that there is no difference between physiological and anxiety influence of composing music on pediatric asthma patients
There is sufficient statistical evidence to suggest that listening to music has an influence on the anxiety of pediatric asthma patients however, the nature of the influence is not specified and more information is needed to draw a proper conclusion

Answers
Given:
The inequality is:
[tex]-20t>-80[/tex]
To find:
The solution for the given inequality and graph of it.
Solution:
We have,
[tex]-20t>-80[/tex]
Divide both sides by -20 and change the sign of inequality because inequality is divided by a negative number.
[tex]\dfrac{-20t}{-20}<\dfrac{-80}{-20}[/tex]
[tex]t<4[/tex]
Therefore, the solution for the given inequality is [tex]t<4[/tex].
All the value less than 4 are in the solution set. It means all the values on the left side of 4 are in the solution set.
Since 4 is not included in the solution set, therefore there is an open circle at 4.
The graph for the given inequality is shown below:
