The correct option is the third option
Graph of InequalitiesFrom the question, we are to determine the system of inequalities that represents the graph
The equation of the solid line is y = -x +4
Since the lower part of the graph was shaded
Then,
The inequality that represents the solid line is
y ≤ -x +4
The equation of the dotted line is y = 3x -1
Since the lower part of the graph was shaded,
Then,
The inequality that represents the solid line is
y < 3x-1
Hence, the system of inequalities that represent the graph is
y ≤ -x +4
y < 3x-1

Tamika has a spinner with 5 equal sections – red, blue, green, yellow, and purple. She plans to spin it 150 times. Predict how many times she should expect the pointer to land on either green or yellow.
Answers
Probability helps us to know the chances of an event occurring. The number of times Tamika should expect the spinner to land on green or yellow is 60.
What is Probability?
Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Total number of sections on the spinner = 5
Number of sections with green or yellow sections = 2
Number of trials = 150
Now, the number of times Tamika should expect the spinner to land on green or yellow is,
Expected Number of lands on green or yellow = 150 × (2/5) = 60
Hence, the number of times Tamika should expect the spinner to land on green or yellow is 60.

The question was incomplete. Below you can find the missing content.
ABC is a right-angled triangle.
b=16 cm
∠C=38°
Calculate the length of AB. Give your answer correct to 2 decimal places.
The picture is also attached below.
The length of the side AB is 9.85 cm.
From the triangle, it is given that
b= AC=16 cm
∠C=38°
Given that ΔABC is a right-angled triangle.
where ∠B=90°
So, here we can apply the SOH CAH TOA identity
As we know the value of sinθ is the ratio of the opposite side and the hypotenuse of the angle θ.
So, sinθ = opposite side/ hypotenuse
In triangle ΔABC
⇒ sin 38°= AB/AC
⇒ sin 38°= AB/16
⇒ AB= 16 sin 38°
⇒ AB= 9.85 cm
Therefore the length of the side AB is 9.85 cm.

Which rule describes the composition of transformations that maps ΔDEF to ΔD''E''F''?To transform a shape is to alter its dimensions and relative placement.
To convert from DEF to D"E"F, use this rule:
(b) T-5,00 RO, 90°(x, y)
From the complete question,
When DEF is spun 90 degrees counterclockwise, it becomes GH.
Then, 5 units were subtracted from the right and translated to the left.
Assume a rotation of 90 degrees counterclockwise, and write it as:
RO, 90°(x,y)
As a symbol, the leftward translation of 5 units looks like this:
T-5,0(x,y)
When both transformations are combined, we have:
T-5,0 R0.90° (x. y)

Answer: The function is decreasing for all real values of x where x < 1.5.
Step-by-step explanation:
The axis of symmetry is [tex]x=\frac{4-1}{2}=1.5[/tex]

You roll a fair six-sided die twice. Find the probability of rolling a 2 the first time and a number greater than 4 the second time.
Answers
Answer:
1/18
Step-by-step explanation:
So to find the probability of two independent events, you simply multiply the two probabilities. So the probability of rolling any individual number is 1/6 because there's 6 possibilities, and there are no duplicate numbers. So the probability of rolling a 2 the first time is 1/6. The probability of rolling a number greater than 4 has a probability of 2/6, since the numbers 5 and 6 are both greater than 4. This can be further simplified to 1/3. Multiplying these two probabilities gives you 1/18

A Pew Research study finds that 23% of Americans use only a cell phone, and no land line, for making phone calls (The Wall Street Journal, October 14, 2010). A year later, a researcher samples 200 Americans and finds that 51 of them use only cell phones for making phone calls. Test whether the proportion of Americans who solely use cell phones to make phone calls differs from 23%. Use the .05 level of significance.

Using the z-distribution, it is found that since the p-value is greater than 0.05, the proportion does not differ from 23%.
What are the hypotheses tested?At the null hypotheses, it is tested if the proportion is of 23%, that is:
[tex]H_0: p = 0.23[/tex]
At the alternative hypotheses, it is tested if the proportion differs from 23%, hence:
[tex]H_1: p \neq 0.23[/tex]
What is the test statistic?The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.The parameters are given as follows:
[tex]p = 0.23, n = 200, \overline{p} = \frac{51}{200} = 0.255[/tex]
The value of the test statistic is:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.255 - 0.23}{\sqrt{\frac{0.23(0.77)}{200}}}[/tex]
z = 0.84.
Using a calculator and considering a two-tailed test, as we are testing if the proportion is different of a value, with z = 0.84, the p-value is of 0.4.
Since the p-value is greater than 0.05, the proportion does not differ from 23%.

pls pls help
Answers
Answer:
x = 65 , y = 64
Step-by-step explanation:
y - 16 and 2y + 4 are same- side interior angles and sum to 180° , that is
y - 16 + 2y + 4 = 180
3y - 12 = 180 ( add 12 to both sides )
3y = 192 ( divide both sides by 3 )
y = 64
then
2y + 4 = 2(64) + 4 = 128 + 4 = 132
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2y + 4 is an exterior angle of the triangle , then
x + 67 = 132 ( subtract 67 from both sides )
x = 65
