What is the answer to 6m+2.3=-9.7
Answer:
m = [tex]\frac{37}{30}[/tex] or 1.23
Step-by-step explanation:
6m + 2.3 = 9.7
6m = 9.7 - 2.3
6m = 7.4
m = [tex]\frac{37}{30}[/tex] or 1.23

a toy car costing 500.00 is reduced by 10% in the sale how much does it cost now?
After the 10% reduction in the price of the toy car, the car costs 450.
In order to determine the cost of the toy car after the price was reduced by 10%, the first step is to determine what 10% of $500 is.
10% x 500
0.1 x 500 = 50.
The second step is to subtract the value of the 10% price reduction from the original cost of the toy car.
500 - 50 = 450

The area of the circle semicircle will be 13288.28 square centimeters.
What is the area of a circle?Suppose the circle has a radius of 'r' units, then, its area is given as:
A = πr² square unit
The radius of the semicircle is 92 cm.
The area of the semicircle is half of the area of the circle.
Then the area of the circle semicircle will be
A = π x 92² / 2
A = π x 8464/ 2
A = 4232 x 3.14
A = 13288.48 square cm

Answer: (1,10)
Step-by-step explanation:
Assuming these are the correctly written equations:
-x + 5y = 49, and
x - 4y = -39
I'll rewrite them:
5y = x + 49
y = (1/5)x + (49/5)
-4y = -x -39
y = (1/4)x + (39/4)

Write a formula for the volume V of a prism where B is the area of the base and h is height
Answer:
a pyramidal prism is 1/3 the volume of a similar rectangular prism of same base and height
so V=(1/3)bh
V=36
H=6
find area of base
36=(1/3)b6
36=2b
divide both sides by 2
18=b
the area of the base is 18 square units
Step-by-step explanation:
the answer is : V= B.h
The claim is that for 10 am body temp of males the mean is less than 98.6 f the sample size is n = 38 and the test statistic is t=-3.768
Answer:
See below
Step-by-step explanation:
The null hypothesis would be [tex]H_o:\mu\leq98.6[/tex] which would suggest the claim that the mean body temperature for males is equal to or less than 98.6°
The alternate hypothesis would be [tex]H_1:\mu>98.6[/tex] which would suggest that the mean body temperature for males is greater than 98.6°
The test statistic, t, is given to us as [tex]t=-3.77[/tex], rounded to 2 decimal places
We can determine the p-value by calculating tcdf(-1e99,-3.77,37). This means that we are finding the area less than the t-statistic with degrees of freedom equal to df=n-1=38-1=37. Therefore, the p-value is 0.000285 when evaluated.
Therefore, because our p-value is less than our significance level of α=0.01, there is no sufficient evidence to prove that the claim that for 10 AM body temperatures for males, the mean is less than 98.6°F, is true. We reject the null hypothesis, in other words, because the p-value suggests that it's unlikely that the null hypothesis is true.
The null hypothesis is rejected since the p-value shows that it is unlikely to be true.
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter. Using sample data, hypothesis testing is performed to examine the plausibility of a theory.
As per the given question, the required solution would be as:
A) Hypothesis test :
The null and alternative hypothesis is
Hi : u = 98.6
Ha : u < 98.6
B) Test statistic is t = -3.831
C) sample size, n= 31
degree of freedom,
df = n -1 = 31 - 1 = 30
P-value = p(t < -3.831 )
= 0.0003 (from t table)
d) P-value < 0.10, reject the null hypothesis.
is, support
As a result, because our p-value is less than our significance level of =0.01, there is insufficient evidence to support the assertion that the mean body temperature for men at 10 AM is less than 98.6°F.
Thus, we reject the null hypothesis since the p-value shows that it is unlikely to be true.

Answer:
y=-2x-7
Step-by-step explanation:
To find the slope intercept form:
y+mx+b
m is the slope and b is the y-intercept.
We can take the first two points and find the slope by:
[tex]\frac{y2-y1}{x2-x1}[/tex] ->
[tex]\frac{-5-3}{-1- - 5}[/tex] = -2.
That’s the slope.
For the y-intercept we solve the equation:
y=−2(−5)+b -> b = -7
now we have the slope and y-intercept so the equation is:
y=-2x-7
Hope that helps!

Answer:
∠DOB=108°
Step-by-step explanation:
∠AOD=∠COB=y
∠AOC=3.5y-y-y
=1.5y
3.5y+1.5y=360° (angles at a pt)
5y=360°
y=360°÷5
=72°
1.5y=72°×1.5
=108°
Hence, ∠DOB=108°.
Answer:
108
Step-by-step explanation:
Call the angle facing east x. The angle facing west is also x. The angle facing north, (thus the angle facing south) is given and is y. You can tell that if you take y twice and x once you get 3.5y, and it's easy to spot that x+y=180. Rest is simple math as in the image added - sorry for the handwriting. With simple algebra (you substitute back and forth) you should get x = 108 degrees.

What can you multiply by to find:
50% of a number?
10% of a number?
75% of a number?
Answer:
1. 50% of a number
0.5
2. 10% of a number
0.1
3. 75% of a number
0.75
Step-by-step explanation:
this is because a percentage is the same as a decimal or a fraction
so 50% is 0.5 or 50/100
taking 50% of something is the same as multiplying by 50% or 0.5 or 50/100
same with 10% and 75%
