Answer:
It will take 17.5 minutes to reach 50 degrees F.
Step-by-step explanation:
Current temperature = -13 degrees F
With the engine on, the temperature goes up by 3.6°F per minute.
Let us assume that it takes x minutes to reach 50 degrees F.
So, the time taken will be =
=> 
=> 
x = 17.5 minutes
The expression that tells how much the temperature needs to change from -13°F to 50°F is :
It will take 17.5 minutes to reach 50 degrees F.
Answer:
Numeric form involving exponents
Step-by-step explanation:
Answer: 3.5 + 4t ≤ 39.5
Step-by-step explanation: To represent this situation we wrote an inequality.
Answer:
z=116 (opposite angles are equal)
y=180-(116+27)=37(angles in a triangle sum up to 180)
x:
(z) + (27+x) =180(interior angles on same side are supplementary
116 + 27+ x =180
x= 37
The results, t (22) = 1.08, p > 0.05, specify that the null hypothesis is plausible. In addition, it is a classification of hypothesis in statistics that puts forward no statistical significance occurs in group of specified interpretations. The null hypothesis tries to display that no variation occurs among variables or that a single variable is no dissimilar than its mean. It is supposed to be true up until statistical evidence nullifies it for an substitute hypothesis. The statistical significance defines that a result from testing or investigating is not likely to happen randomly or by coincidental but is as a substitute likely to be attributable to a precise reason.
