During a basketball game, chiyann made 15 baskets. She made three more baskets then twice number of baskets made by whitney. How many baskets did whitney make
Answer:
Whitney made 6 baskets
Step-by-step explanation:
Let the number of baskets made by Whitney be x.
The 15 baskets made by
Chiyann is equal to 2 times plus 3 what Whitney made
Mathematically what she made would be 2x + 3
To get x, we equate this equation to 15
2x + 3 = 15
2x = 12
x = 12/2
x = 6 baskets

Answer:
1) 2002
2) 92
Step-by-step explanation:
1)
First, you need to find the area of the triangular base. The height of the triangle is 7, and the base is 26, meaning that the area is 7*26/2=91. Multiplying this by the length of the prism, you get 2002 cubic meters.
2)
First, you need to find the area of the trapezoidal base. The two bases of the trapezoid have lengths 12 and 11, while the height is 8, meaning that the area is 8*(12+11)/2=92 cubic centimeters.

Pablo makes a spinner to model the probability of simultaneously flipping a "heads" on a nickel, a "heads" on a dime, and a "heads" on a quarter. He divides his spinner wheel into sections for each possible combination of coin flips, and he colors green the section representing simultaneously flipping three "heads." If he decides to spin the arrow on the spinner 24 times, how many times can he predict the arrow will land on the green section?
times
Using proportions, it is found that he predicts that the arrow will land on the green section 24 times.
What is a proportion?A proportion is a fraction of a total amount.
Considering that each trial has a 1/2 probability of resulting in heads, the fraction correponding to the probability of simultaneously flipping three "heads" is given by:
[tex]p = \left(\frac{1}{2}\right)^3 = \frac{1}{8}[/tex]
Considering that he does this 24 times, we apply the proportion, hence:
[tex]\frac{1}{8} \times 24 = 3[/tex].
He predicts that the arrow will land on the green section 24 times.

let's reffer to:
gumbo (x)
raspberry (y) so,
8x + 9y =14. 3 (1)
6x + 3y = 8.1 (2)
devide (2) by 3
2x + y = 2.7
y = 2.7 - 2x (3)
substitute 3 in 1
8x + 9(2.7 - 2x) = 14.3
8x + 24.3 - 18x = 14.3

The names of 11 boys and 9 girls from your class are put into a hat. What is the probability that the first two names chosen will both be girls?
Show work please and Thanks
Answer:
18/95
Step-by-step explanation:
There are a total of 20 names, 9 of which are girl names.
The probability that the first name is a girl name is 9/20.
Since there's one less girl name in the hat, there are now a total of 19 names, 8 of which are girl names. So the probability that the second name is a girl name is 8/19.
The total probability is (9/20) (8/19) = 18/95.

$3,000 is invested in an account that earns 3% annually interest, compounded monthly.
What is the value of the account after 10 years ?
Given the principal and annual interest rate, the total amount accrued after 10 years is approximately $4,048.06.
The compound interest formula is expressed mathematically as;
A = P(1 + r/n)^(n*t)
Where A is amount accrued, P is principal, r is interest rate, n is number of times interest applied per time period and t is time.
Given the data in the question;
Principal P = $3,000Annual interest rate r = 3% = 3/100 = 0.03Compounded monthly n = 12Time t = 10 yearsPlug the given values into the formula above and solve for A.
A = P(1 + r/n)^(n*t)
A = 3000(1 + 0.03/12)^(12 × 10)
A = 3000(1 + 0.0025 )¹²⁰
A = 3000(1.0025 )¹²⁰
A = 3000( 1.34935354 )
A = $4,048.06
Given the principal and annual interest rate, the total amount accrued after 10 years is approximately $4,048.06.

Step-by-step explanation:
Step 1: Add -2y to both sides.
Step 2: Add 8 to both sides.
Step 3: Divide both sides by 2.
what are the steps for this question?
Answer:
1. Add 5 to both sides
2. Divide both sides by 2
3. Take the square root of both sides
4. Subtract 2 from both sides
Step-by-step explanation:
2(x+2)²-5=93
Add 5 to both sides
2(x+2)²=98
Divide both sides by 2
(x+2)²=49
Square root both sides
x+2=7
Subtract 2 from both sides
x=5
Answer:
Let's solve the equation. To do this, we have to get x by itself. Perform the opposite of what is being done to the equation.
1. Add 5 to both sides, since 5 is being subtracted
2(x+2)^2-5=93
2(x+2)^2-5+5=93+5
2(x+2)^2=93+5
2(x+2)^2=98
2. Divide both sides by 2, since 2 is being multiplied
2(x+2)^2=98
2(x+2)^2/2=98/2
(x+2)^2=49
3. Take the square root of both sides, since x+2 is being squared
(x+2)^2=49
√(x+2)^2=√49
x+2=√49
x+2=7
4. Subtract 2 from both sides since 2 is being added
x+2=7
x+2-2=7-2
x=7-2
x=5

Answer:
Height Length: ( About ) 3.3 yards; Option B
Step-by-step explanation:
~ We are given the Area of this triangle, so let us apply the area of a triangle formula 1/2 * base * height ~
The base is known the be 4.1 yards, the Area 6.8 yards^2, so let us substitute these values into the formula for a triangle as to solve for height. At the same time let us declare x ⇒ height of the triangle:
6.8 = 1/2 * 4.1 * x,
6.8 = 2.05 * x,
x = 6.8/2.05,
Height Length: ( About ) 3.3 yards
A special cable has a mean breaking strength of 1131 pounds. The standard deviation of the population is 333 pounds. A researcher selects a sample of 30 cables with a mean of 931 pounds. Can one reject the claim that the mean breaking strength is less than 1131 pounds? (Use the 0.05 level of significance)
Answer:
[tex]z=\frac{931-1131}{\frac{333}{\sqrt{30}}}=-3.290[/tex]
Now we can calculate the p value using the alternative hypothesis:
[tex]p_v =P(z<-3.290)=0.0005[/tex]
Since the p value is lower than the significance level of 0.05 we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly less than 1131
Step-by-step explanation:
Information given
[tex]\bar X=931[/tex] represent the sample mean
[tex]\sigma=333[/tex] represent the population standard deviation
[tex]n=30[/tex] sample size
[tex]\mu_o =1131[/tex] represent the value to check
[tex]\alpha=0.05[/tex] represent the significance level
z would represent the statistic
[tex]p_v[/tex] represent the p value
System of hypothesis
We want to verify if the true mean is less than 1131, the system of hypothesis would be:
Null hypothesis:[tex]\mu \geq 1131[/tex]
Alternative hypothesis:[tex]\mu <1131[/tex]
The statistic is given by:
[tex]z=\frac{\bar X-\mu_o}{\frac{\sigma}{\sqrt{n}}}[/tex] (1)
Reaplacing we got:
[tex]z=\frac{931-1131}{\frac{333}{\sqrt{30}}}=-3.290[/tex]
Now we can calculate the p value using the alternative hypothesis:
[tex]p_v =P(z<-3.290)=0.0005[/tex]
Since the p value is lower than the significance level of 0.05 we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly less than 1131
