Answer:
35/8 or 4 3/8
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.

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.
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

How much water must be evaporated from 36 ounces of 1% salt solution to make 9% salt solution?
To obtain a solution that is salt,
nothing ounce(s) of water must be evaporated.
simplify
Answer:
8 ounces to be evaporated
Step-by-step explanation:
There are 2.52 oz of salt (36 * 0.07)
For 2.52 oz to be 9%, the total is 2.52 / 0.09 = 28 oz total
36 - 28 = 8 ounces
Expected rate of return and risk - B.J. Gautney enterprises is evaluating a security. One year treasury bills are currently paying 4.3 %. Calculate the investment's expected return and its standard deviation. Should Gautney invest in this security?
Probability/ return: 0.20/ -4%; 0.50/ 4%; 0.10/ 7%; 0.20/ 8%.
The investment's expected return is _% (round the two decimal places)
The investment's standard deviation is % (round the two decimal places)
Should Gautney invest in this security? (select the best choice below)
a) yes. B.J. Gautney Enterprices should invest in this investment because the return is lower than treasury bill and the level of risk higher than the treasury bill.
B) no. B.J. Gautney Enterprises should not invest in this investment because the return is lower than the treasury bill and the level of risk higher than the treasury bill.
Answer:
Step-by-step explanation:
[tex]\text{Investment's Expected Return} = (0.20 \times -0.04) + (0.50 \times 0.04) + (0.10 \times 0.07) + (0.20 \times 0.08) \\ \\ = (-0.008)+(0.02)+(0.007) + (0.016) \\ \\ \text{= 0.035}\\ \\ = 3.50\%}[/tex]

What is the area of the trapezoid shown below?
Answer: where is the trapezoid
Step-by-step explanation:
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?
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°
