a factory makes car batteries. The probability that a battery is defective is 1/13. If 200 batteries are tested about how many are expected t be defective.
A. 20
B. 15
C. 187
D. 13
Answer:
defective battery=200×1/13=15.3=15 is your answer
Number of expected defective batteries are option(B) 15
What is Probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given,
Probability that a battery is defective = [tex]\frac{1}{13}[/tex]
Total number of batteries = 200 batteries
Number of expected defective batteries = [tex]200(\frac{1}{13})[/tex] ≅15 batteries
Hence, the number of expected defective batteries are option (B) 15 batteries

1. FIND THE AREA OF THE FIGURE.
plzz help meee.!.!.!
Answer:
The answer isn't there
Step-by-step explanation:
We can divide the figure into a rectangle and triangle and add the areas. The area of the rectangle would be length times width: 14 × 12 = 168. The area of a right angled triangle is [tex]\frac{ab}{2}[/tex], where a and b are both legs. a=12 and b=8, so the area would be [tex]\frac{12*8}{2}[/tex] which equals [tex]\frac{96}{2}[/tex], which is 48. Then we add both the areas, 168 + 48 = 216

Rectangle=864
Step-by-step explanation:
Triangle:
4*3=12, *2=24
6*5=30
6*3=16
4*6=24
24+24=48, +30=78, +16=94
Rectangle:
30*7=210, +210=420
30*6=180, +180=360
7*6=42, +42=84
420+360=780, +84=864

Write the equation of the line that passes through the points (7, –9)
and (1,-4). Put your answer in fully reduced point-slope form,
unless it is a vertical or horizontal line.
Answer:
y=[tex]\frac{-5}{6}[/tex]x+14[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
The equation of a line is y=mx+b
to find the equation of the line you need its gradient(m) and its y intercept(b)
the gradient is
[tex]\frac{y1-y2}{x1-x2}[/tex]
y1= the y value of the first point which is -9
y2=the y value of the second point which is -4
x1=the x value of the first point which is 7
x2=the x value of the first point which is 1
then input the values into the equation
[tex]\frac{(-9)-(-4)}{(7)-(1)}[/tex]
=[tex]\frac{-9+4}{6}[/tex]
=[tex]\frac{-5}{6}[/tex]
to find the y just times the x by the gradient and then minus it from the y
-9-(7 x [tex]\frac{-5}{6}[/tex])=14[tex]\frac{5}{6}[/tex]
making the equation y=[tex]\frac{-5}{6}[/tex]x+14[tex]\frac{5}{6}[/tex]
The ratio is 2:5 red beads to blue beads. If you have a TOTAL of 21 beads, how many are red, and how many are blue beads?
Answer:
Number of red beads = 6
Number of blue beads = 15
Step-by-step explanation:
Number of total beads = 21
Ratio of red beads to the blue beads = 2 : 5
Therefore, number of red beads I have = [tex]\frac{2}{2+5}(\text{Total number of beads})[/tex]
= [tex]\frac{2}{7}\times 21[/tex]
= 6 beads
Number of blue beads = [tex]\frac{5}{2+5}\times (21)[/tex]
= [tex]\frac{5}{7}\times 21[/tex]
= 15 beads
Therefore, number of red beads = 6
And number of blue beads = 15

40 seventh-graders are expected to attend summer camp.

Mariela recolecto 625 mililitros de agua que gotea de su caño en 10 minutos, ella desea saber ¿cuanta agua gastara en una semana ?
Answer:
En una semana gastará 705,6 litros.
Step-by-step explanation:
Con la información proporcionada, puedes calcular cuánta agua gastará por día usando una regla de tres teniendo en cuenta que un día tiene 24 horas y estas equivalen a 1440 minutos. Además, puedes convertir los 700 ml a litros, considerando que 1 litro son 1000 mL, lo que significa que los 700 mL equivalen a 700/1000=0,7 Litros.
10 min → 0,7 L
1440 min → x
x=(1440*0,7)/10
x=100,8 L
Ahora que conoces la cantidad de agua que gastará por día, puedes multiplicar esta cantidad por 7 que es el número de días en una semana:
100,8*7=705,6 L
De acuerdo a esto, la respuesta es que en una semana gastará 705,6 litros.

Answer and Step-by-step explanation:
10 and 20 are the initial amounts, so they don't get a variable. The 3 dollars and 2 dollars every mile gets the variable since the occur every mile.
The equations are:
Blank 1: 3x + 10
Blank 2: 2x + 20
To find when they are equal, we equal the equations together.
3x + 10 = 2x + 20
x = 10
Plug 10 into either equation and solve.
Blank 3: 10 (At 10 miles, the equations are equal)
Blank 4: $40 (The will equal $40)
