Answer:
H0 : u ≥ 10 against the claim Ha: u < 10
Step-by-step explanation:
The mean breaking strength of a ceramic insulator must be at least 10 psi.
(At least means greater or equal to ). As it is already given in the data the null and alternate hypotheses will be formulated according to it.
H0 : u ≥ 10 against the claim Ha: u < 10
The null hypothesis is the mean breaking strength of a ceramic insulator must be at least 10 psi
and the alternate hypothesis is
the mean breaking strength of a ceramic insulator is less than 10 psi

Answer:
base = 3 units
height = 5 units
area = 1/2 x 3 x 5 = 7.5 square units
Answer:
[tex]b[/tex] = 3 units
[tex]h[/tex] = 5 units
[tex]a[/tex] = 7.5 units
Step-by-step explanation:
We can find the base of the figure by counting the number of units from the left to the right of the triangle. So, we can find that the base is 3 units.
The height of the figure can be found by counting how many units the figure measures from the tip to the bottom. The height, then, is 5 units.
The easiest way to find the area of a right triangle is to imagine it as a rectangle, with the same [tex]l[/tex] (length) and [tex]w[/tex] (width) dimensions, and then divide the area of the rectangle by two.
So, to find the area of this rectangle, multiply the length and width, 3 and 5, together.
3 · 5 = 15
Then, we can divide this product by two.
[tex]\frac{15}{2}[/tex] = 7.5
The area is 7.5 units².
Hope this helped :] Good luck!

Select How many numbers are 10 units from 0 on the number line?
Answer:
2 numbers are 10 units from 0
Step-by-step explanation:
2 numbers are 10 units from 0. If you start from zero and count 10 units to the right, you should be at a positive number. But, you can also move 10 units to the left. If you do this, you should be at a negative number that is ALSO 10 units away from 0, just in a different direction than positive number. both are 10 units from 0. There always 2 numbers, one 10 units to the right of zero, and one 10 units to the left of zero. Hope this helped! Tell me if I'm wrong or right.
Answer: 2 numbers
Step-by-step explanation:
I'm assuming you are talking about a normal number line and if so, you can count 10 units up and down.
When you do that, you find -10 and 10 which are two numbers so the answer would be 2 numbers
This is assuming that you are talking about a normal number line
Please tell me if I'm right or wrong and I hope this helps someone!
Please help me thanks!
Answer:
3rd Option[tex] \frac{6}{17} [/tex]
Step-by-step explanation:
Given,
No. of blue marbles = 6
No. of green marbles = 6
No. of red marbles = 5
So,
Total no. of marbles = 6+6+5 = 17
Therefore,
Probability of not getting blue marbles
[tex] = \frac{6}{17} [/tex]
Hence,
3rd option is correct.
Help I need a real answer plz
Answer:
y=-3/4x-4
Step-by-step explanation:
To start, you know what m is; it's just the slope, which you said was -3/4. So you can right away fill in the equation for a line somewhat to read:
y=-3/4x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-8,2). When x of the line is -8, y of the line must be 2.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the -3/4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-8,2).
So, why not plug in for x the number -8 and for y the number 2? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-8,2). y=mx+b or 2=-3/4 × -8+b, or solving for b: b=2-(-3/4)(-8). b=-4.
The equation of the line that passes through the point (-8,2) with a slope of -3/4
is
y=-3/4x-4

Jeff bought 7 pounds of chocolate
and spent $8.89. How much is one
pound of chocolate?
Answer:
1.27
Step-by-step explanation:
Answer:
$1.27
Step-by-step explanation:
Divide the total cost by the number of things you have to get the unit cost. Unit cost is the amount per item
$8.89/7 items = $1.27 per 1 pound of chocolate

Which figure can be formed from the net?
Answer:
Option B
Step-by-step explanation:
The figure that can be formed from the net must definitely be the figure that has a square base with its side measuring 4 cm each and a slant height of 6 cm.
This, the figure in option B can be formed form the net because it has the same base measurement of 4 cm and slant height of 6 cm as with the net.
A two-sample t-test for a difference in means was conducted to investigate whether the average wait time at a fast food restaurant in Town A was longer than the average wait time at a fast food restaurant in Town B. With all conditions for inference met, the test produced a test statistic of t=2.42 and a p-value of 0.011.
Based on the p-value and a significance level of α=0.02, which of the following is a correct conclusion?
Answer:
B
Step-by-step explanation:

Solve for x using
cross multiplication.
2x + 2 = x-4
11
6
x = [?]
Enter
you would cross multiply meaning 6(2x+2)=11(x-4) Then you distribute 6 so it would be 12x+12=11x-44 then you have to move the constant and the variable so 12x-11x= -44-12 so then the answer would be x = -56
What does a data distribute look like if it's MAD equals zero
Answer:
Because a MAD is the average of distances, which can never be negative, the MAD is always zero or a positive number.

A 52-in TV measures 52 inches along its diagonal (corner to corner measure). If that TV is 33.6 inches high, how wide is it?
Step-by-step explanation:
Use Pythagoras' theorem
[tex] {a}^{2} = b {}^{2} + c {}^{2} [/tex]
52² = 33.6² + x²
solve for x
Answer:
1575.04
Step-by-step explanation:
Using Pythagoras theorem,
a^2+b^2=C^2
52^2-33.6^2=1575.04

What is the equation of the line that passes through the point (1, 3) and is perpendicular to the line 2x+3y=15?
Answer:
y = 3/2x + 3/2
Step-by-step explanation:
perpendicular to: y = -2/3x + 5
so slope of new line must be 3/2
y = mx + b
3 = 1(3/2) + b
6/2 = 3/2 + b
b = 3/2
