G let z be a random variable with a standard normal distribution. find the indicated probability. p(z ≤ −0.27)
The probability P(Z <= -0.27) in a standard normal distribution is determined by finding the corresponding right-tail probability of Z = 0.27 and subtracting it from 1, reflecting the distribution's symmetry.
To find the probability P(Z \<= -0.27), we use the properties of the standard normal distribution, which is symmetric about zero. The probability of Z scoring below -0.27 is equal to the probability of Z scoring above 0.27 due to this symmetry. Looking up the corresponding value for Z = 0.27 in a standard normal table, or using a calculator, we would find the right-tail probability. To get our desired left-tail probability for Z = -0.27, we subtract this from 1. For example, if the right-tail probability for Z = 0.27 was 0.3936, then P(Z \<= -0.27) would be 1 - 0.3936 = 0.6064.
An electronics shop offers a small ic chip for $1.50 per unit and $4.00 for large ic chip. on a certain day, 2200 chips were sold and $5050 is collected. how many small ic chips and how many large ic chips were sold?
To determine the number of small and large IC chips sold, we set up a system of linear equations with the given total number of chips (2200) and total earnings ($5050). Solving the system, we found that 1500 small IC chips and 700 large IC chips were sold.
To solve the problem, we can set up a system of linear equations to represent the sales for small and large IC chips. We have two unknowns: the number of small IC chips (let's call it x) and the number of large IC chips (let's call it y). We have two pieces of information to create our equations:
The total number of chips sold is 2200, so x + y = 2200.
The total amount collected is $5050, so 1.50x + 4.00y = 5050.
Solving this system of equations, we multiply the first equation by 1.50 to align it with the second equation:
1.50x + 1.50y = 3300 (Multiply the first equation)
1.50x + 4.00y = 5050 (Second equation)
Subtracting the first new equation from the second gives us:
2.50y = 1750
Dividing both sides by 2.50 to find y gives us y = 700. That means 700 large IC chips were sold. Now, we can substitute y in the first equation to find x:
x + 700 = 2200
x = 2200 - 700
x = 1500
Hence, 1500 small IC chips and 700 large IC chips were sold.

Estimate by division ..70/9.24
Here we have to divide 70 by 9.24.
we can first covert the decimal 9.24 into fraction, shifting the decimal two units to the right and dividing by 100, we have
9.24 = 924/100
Now let us divide 70 by 924/100
in division of fraction we take reciprocal of second fraction and multiply it with first.
reciprocal of 924/100 is 100/924.
multiplying 70* 100/924, we have
[tex] 70 * \frac{100}{924} [/tex]
[tex] = \frac{7000}{924} [/tex]
converting into decimal we have
[tex] \frac{7000}{924} = 7.5757..... [/tex]

In which graph does y vary directly as x? It’s not C, I got it wrong.
What is the sum of 4.2 × 105 and 5.3 × 10^5?
A.)95 × 10^5
B.)95 × 10^10
C.)9.5 × 10^5
D.)9.5 × 10^10
Answer:
Option C.
Step-by-step explanation:
The two expressions are [tex]4.2\times 10^{5}[/tex] and [tex]5.3\times 10^{5}[/tex]
We have to find the total of these two terms.
[tex](4.2\times 10^{5}[/tex] + [tex]5.3\times 10^{5})[/tex]
Now we take out [tex]10^{5}[/tex] as a common term.
[tex]10^{5}(4.2+5.3)[/tex]
= [tex]9.5\times 10^{5}[/tex]
Therefore, Option C. will be the answer.

Which of the following functions is graphed below?!?
The given graph is for a piecewise function consisting of two intervals:
(1) x ≤ 1 ⇒⇒⇒ the graph in this interval like a cubic function.
(2) x > 1 ⇒⇒⇒ the graph in this interval like a quadratic function
By comparing to the given options
The answer is option c.
Answer:
Option C is correct.
Explanation:
A piece-wise function is a function which is defined by multiple sub-functions, each sub-function applying to a certain interval of the main function's domain.
From the graph we can see that the function is made up of 2 pieces.
Solid dot means- Including
Open-dot means - not- including.
As we can see that the boundary lines are at x=1.
We have to look each line separately to determine each equation:
when [tex]x>1[/tex], it gives the function [tex]y=x^2+4[/tex] and
when [tex]x\leq 1[/tex], it gives the function [tex]y =x^3-2[/tex].
So, the piece-wise function is:
[tex]y=\left \{ {{x^3-2}, x\leq1 \atop {x^2+4}, x>1} \right.[/tex]
Surface area of right cone radius of 8 and 14 height
A. 896
B. 224
C. 176
D. 167
The value of Surface area of right cone with radius of 8 and 14 height is,
⇒ SA = 606.31
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Radius of cone = 8
And, Height = 14
We know that;
Surface area of right cone is,
SA = πr (r + √h² + r²)
SA = 3.14 × 8 (8 + √14² + 8²)
SA = 606.31
Thus, The value of Surface area of right cone with radius of 8 and 14 height is,
⇒ SA = 606.31

Which of the following functions is graphed below?
The graph consists of two parts: left part (with sign < or ≤) - parabola and right part (with sign > or ≥) - straight line.
Determine signs:
From the diagram you can see that the right endpoint (4,19) of parabola is not included. This means that x cannot be equal to 4 at this part of graph and the sign should be <.
Also you can see that the left endpoint (4,8) of line is included. This means that x=4 belongs to the right part and the sign should be ≥.
Using previous conclusions, you can state that correct choice is D.
